Return (https://return.energy) is hiring a DevOps engineer who will build and run the infrastructure behind platforms that accelerate the transition to carbon-free energy. Return's main activity is building and operating industrial-size Battery Energy Storage Systems. Our operations are located in the Netherlands, Germany, Belgium, and Spain. You will be making a measurable (country-level) impact on the transition to renewable energy. Return recently raised €300M to support its growth.
While we employ over 120 people, Return's technical team is still small (15 people). Our platform automates processes in energy storage, monitoring, market optimization, sales, project management, procurement, construction, and customer service. Behind it sits a mix of EU cloud and on-site compute at our battery sites, with strict uptime and security requirements.
During the first four years of operation, we laid the foundation for our platforms, and we are ready to scale up. This is why we are looking for an experienced DevOps engineer who can own the full picture: cloud environments, self-hosted infrastructure at our BESS sites, and the operations centers in Amsterdam and Eindhoven from which we run the fleet.
Your primary focus will be to design, automate, and operate the infrastructure that our virtual battery platform runs on. That means EU-only cloud providers for application workloads, hardened on-premise setups at our sites, and the connectivity in between. You will be the person who decides what gets deployed where, and who makes sure it stays up and stays secure.

Hey this is Brian from Gain Compliance, we've had success hiring out of a hacker news thread before, so let's give it a spin again.
We are a small company that builds financial reporting tools for the insurance industry. While the domain might be foreign to most, we are having a lot of fun building modern web software with React, Python and Node running on GCP infrastructure. You'll be joining 7 other engineers split into two full stack product focused teams.

Join (https://join.build) | Staff Software Engineer | Remote | $175K–$205K + equity
Join builds collaboration software for the construction industry — helping contractors, owners, and architects coordinate on high-value projects. React, Golang, Postgres. We deploy to AWS via Terraform.
We're hiring multiple staff engineers across a range of profiles: frontend-heavy, fullstack, and backend-heavy. We're especially looking for 1–2 engineers with architect-level frontend chops (React, TypeScript, state management, perf) who can own UI quality and level up the team. But we're also very interested in strong Go/Postgres or infra/ops backgrounds.
Day to day you'll write code (25–75%), review PRs (25–50%), and pair/mentor/document (10–20%). You'll act as a technical lead on projects, break down large efforts, and influence architectural decisions across the org. Small cross-functional teams with a designer, PM, and EM.
Stack: React, TypeScript, Golang, Postgres, GraphQL/Apollo, Vite, Cypress, Terraform, AWS (ECS, RDS, Lambda). We lightly use Elastic and are interested in event-driven patterns.
To apply: send resume to jon@join.build. If you are able to please include a PR review you've given that had a positive impact (or a description/snippet if that's confidential).
We make Architect: a Kubernetes runtime that hibernates idle pods in place and wakes them in 50ms with TCP connections intact. Five engineers. You'd be the 6th.
If tracing an x86 instruction in the morning and hunting a control-plane race in the afternoon both sound fun, and you insist on measuring rather than guessing, this is the job.
Customers run Architect for workloads where cold starts hurt: real-time voice & video AI agents, long-warming JVM apps, stateful data services that can't be rescheduled cheaply. 1.0 shipped Q1 2026; you'd join mid-way through 2.0. Seed-stage, VC-funded, a few years of runway. Fully distributed across the Americas and Europe.
- Control plane: per-node DaemonSet streaming checkpoints; admission controller resizing hibernated pods in place.
- Networking and migration: eBPF/XDP at line rate; cross-node live migration to production; cross-cloud next.
You're a senior generalist. Years across the stack: assembly to frontends, hardware-near, comfortable in x86. Tests ship with the code, decisions get worked out in writing, and you measure rather than guess. Strong in Go; willing to use Zig, Rust, or C.
Bonus: eBPF/XDP, CRIU, Linux kernel internals, containerd, gVisor, live migration, or public writing in kernel/container/eBPF land. Strong systems depth and the willingness to pick up the rest is enough on its own.
Y Combinator | Product Engineers on YC's own team | San Francisco | Full Time | $185K-$485K
I'm Ryan, an EM and engineer here at YC. We have a small, 18-person software team with no PMs -- engineers own everything end-to-end.
We build the software behind YC's $6B in investments: tools that help partners evaluate thousands of startups per batch, AI-powered apps that founders use every day, and platforms like Work at a Startup that connect candidates with YC companies. Engineers get unlimited AI tokens -- both for development and to build AI-powered products. What wouldn't you build to help founders + YC with that much firepower?
What makes this different from other roles:
* You'd learn more about startups here than you could possibly imagine. Every batch brings hundreds of founders building things across every industry, and you're right in the middle of it.
* We attend Demo Day, founder dinners, and work directly with partners and many of the companies. (They make great products!)
* We pay well, offer carry in the fund (like equity), and provide generous relocation support if you're not in SF yet.
Two roles open:
* Product Engineer -- full-stack, own the product lifecycle. Rails/React stack. Build tools that power how YC invests in and supports startups. It's a wide range, and sometimes it feels like labs-like work, other times it feels like a supersuit to power founders and our Partners like Garry and Jared.
* Community Builder and Software Engineer -- hybrid role. Run YC's talent-facing programs (meetups, tech talks, career expos) AND build the software that makes them scale. You need to be a great engineer and LOVE to build and support communities.
We're also exploring a Technical Chief of Staff role to work with one of our GPs -- someone who can think analytically, drive operations, and scale what they do with software.
Checkout more about the roles, and email me directly if you're excited to learn more about startups than you will anywhere else - ryan@ycombinator.com
CoPlane (https://coplane.com/) | Product Engineer | NYC (preferred) or Remote (North America) | Full Time
The world doesn't need another ERP. CoPlane is building the Agentic Orchestration platform that enables enterprises to orchestrate intelligent processes across their existing systems. Founded by ex-Stripe/Segment product and tech leads, we're changing how businesses operate their backoffice - helping them scale intelligence not headcount.
We're looking for an exceptional product engineer to grow our small team of engineers that include ex-founders, open source contributors (authors of neovim and neverthrow), and architects of petabyte-scale data platforms.
We are looking for someone that wants to own product features end to end (Python + Typescript/React) but is particularly spiky on frontend and UI. You'll build a platform for billion-dollar enterprises solving their hardest, most mission-critical automation problems.
If you're excited about working at the nexus of data, automation and AI, and want to make a significant impact in an early, well-capitalized startup with large enterprise design partners, we'd love to hear from you.
Entex | Full-stack Dev | Remote (Worldwide) | 60 to 100 %
entex is a small established Swiss IT service provider. We offer some of the classics: IT support, infrastructure, web development and high-end security cameras. We deal with a lot of “boring” tech and it’s great! (Well,
mostly great!)
After a recent change in ownership, we are looking to grow, reinforce the existing team and expand our service offering.
Electrical and mechanical engineering consulting firm in Waterloo, serving the Canadian building construction industry — a market that's still mostly designed the old way. I designed the original platform schema and UX vision; my early code attempts got abandoned when running and growing the firm took priority. The years since have been spent figuring out how to scale this properly and fill those gaps. We're now at the depth and size to support a real build — with no committee in the way, and with my time properly committed to it this time. I'm hiring an exceptional software engineer to take it to the production platform it was always meant to be.
Real users, direct collaboration with the founder, and 20 years of MEP practice plus the platform vision. Few founders building automation in this space bring both.
Profitable, bootstrapped, 18 years old. Equity is earned, not granted — a real cut of a real business, not options in something that may or may not happen.
We're building a system that represents domain knowledge as modular probabilistic models — making analysis rigorous and transparent. Users can connect these models flexibly into larger structures. The system enforces consistency across them, and propagates uncertainty through each step. Our first applications are in finance and scientific research, with use cases ranging from equity valuation and distress monitoring, to particle physics.
We’re building out our team in the following areas:
We're also looking for Domain Experts to collaborate on high-value use cases -- identifying and validating opportunities, shaping them into working solutions with our engineers, and taking them from pilot to production with real users. Practitioners with expertise in Valuation Models, Quantitative Default-Probability Models, or Interest Rate Prediction Models are particularly relevant right now.
Kanary is a personal security platform that monitors the web to identify and reduce risk based on an individual's threat model. An executive has different exposure than a gamer, and our system classifies each person's risk across 55,000+ sources. We've been building since 2020, started in campaign security, data science, and government agencies, backed by Mozilla and Y Combinator. We have 200+ organizations on the platform and are fully funded by our customers.
Attackers have never had better tools. LLMs, social media, and search surface personal data in new ways. A few prompts can launch a deepfake and impersonation campaign. Risk sources appear and disappear across social platforms, telegram chats, and private data broker platforms. Kanary exists to play the cat and mouse game for people at the speed and scale of an agentic internet.
Kanary is a combination of software workflows (crawling, scraping, automation), AI (data classification, research, code generation), and people (analysts trained to support customers and escalate). This is dynamic system and requires an interest in adversarial programming.
We’re growing our team, and seeking a multifaceted engineer (2+ years experience). Our software stack is python, javascript, react, and for LLMs, we use Anthropic, OpenAI, and experiment with model fine tuning as needed. Experience with web scraping, data pipelines, or security tooling is required.
Email steven@kanary.com with something you've built and why it was hard.

- You will be working remote with a team that is all working remote and has been for years. Let's make the best use of our time by not commuting.
- We practice and preach sound development practices. You are likely to learn and grow as a developer while working here.
- You are committed to automated testing of all the software you write (our apps typically have 92%+ test coverage).
- We have a no-drama office policy. We value and cultivate enjoyable working relationships among team members. No jerks allowed!
- We emphasize work/life balance and adopt policies that make sure our people don't get burnt out. For instance, our PTO/Vacation policies are designed so that you actually use them.
- If you apply, we guarantee that we will give you a response, whether "yay" or "nay". No black holes here!

The demand for trusted digital ID is accelerating as AI deepfakes begin to destroy most of the ways we use to verify identity today. How private or secure is it to hold your driver's license or passport up to a webcam to get a bank account? Was it ever private or secure? Stable diffusion can break so much of this already. Society will need trusted digital IDs and credentials. Our mission is to allow them to be controlled by individuals, with safeguards to prevent descents into surveillance states and checkpoint societies.
We are the main implementers of category-defining initiatives such as the digital ID program for the California DMV, and the verifiable digital credentials program in Utah. We are private sector participants in NIST's National Cyber Security of Excellence initiative for privacy-preserving digital ID.
We are hiring skilled engineers who care about making a real impact in improving public services, digital autonomy, and user privacy for the world. We work closely with public sector agencies, and have high regard for public servants. We have a strong engineering and customer-oriented culture, and are not simply a SaaS product or AI wrapper. Our roles are not for the faint of heart: you will be expected to work hard and learn a lot in this role.
Our engineers are ambitious to get outcomes for our customers and their constituents. On any given day, they may write great Rust/C#/TypeScript, deal with mainframe dumps, read policy documents, respond to technical RFIs/RFPs, manage on-prem environments, implement new NFC + Bluetooth protocols in Swift/Kotlin, create CI/CD processes that enforce W3C accessibility guidelines and i18n requirements, rewrite lost specs from disassembled binaries, figure out stablecoin payments, and design new protections for public key infrastructure. It is a team effort, and people with T-shirt shaped skills are able to collaborate and learn a ton from each other every day.
We are interested in candidates who want to be proud of the meaningful impact they make for society, even if it takes time to get right. This is not the right job for someone who wants to "join a cool new AI startup" that implodes or exits in under a year.

Burnin (London or NYC) | Founding Research Scientist + Founding Engineering Lead | Hybrid (Some on-site) | Full-time
We are building the trust stack for AI code generation, targeted at high-stakes computing where wrong numbers cost real money: a statically typed functional language designed for coding models, a compiler whose guarantees double as audit-grade trust infrastructure, and a coding model fine-tuned on the language with compiler fitness as the training signal. Language and model are co-designed.
Small team out of PyTorch, FAIR, and Meta. Strong institutional VC support from our pre-seed; active investor interest heading into seed.
Founding Research Scientist: own the agenda across the language and the model. Type system design, compiler analyses that produce useful fitness gradients, and fine-tuning open-weight coding models on a language with no pretraining footprint. Publish in PL and ML venues. Strongest fits cross between machine learning, programming languages, and formal methods. PhD preferred, equivalent output equally fine. Stack is Rust, Lean 4, Python.
Founding Engineering Lead: own engineering across compiler internals, language runtime, GPU backends, notebook and library tooling, and the AI infrastructure around training, evaluation, model release, and likely public inference. We already support x86 and ARM, CUDA and AMD, macOS and Linux, and the matrix grows. Real feel for statically typed functional programming expected; the kind of engineer who picks up Lean or Haskell on a weekend because they wanted to. Have led engineering before, formally or not. Stack is mostly Rust with Python where it earns its place, primarily on AWS.
Both roles: comfortable with early-stage ambiguity, define your own roadmap, defend it with evidence.

- The SDK for comp scientists: TypeScript, Tengo (a Lua-like workflow DSL — yes, you'll learn it), Rust.
- The data layer: thousands of formats reduced to one. PFrames, Parquet, DataFusion, lazy columnar everything.
- Bioinformatics exposure or appetite to learn it month one. We can teach VDJ recombination; not curiosity.
- Tolerance for sparse docs and niche DSLs. "Fix the SDK, don't work around it."
OFFER
- €90–120k base, real ESOP, ARR-tied bonus — when we grow, you grow, in cash, this year.
- Bizkaia Special Impatriate Regime: ~15–20% effective tax. Beats London / Berlin / Amsterdam net.
- Visa, relocation, soft-landing. No HR, no take-homes. Direct line to engineering.

Intact is not only our lead investor but also a carrier partner, a testament to the confidence the incumbent industry has in what we're building.
This year, we’re growing our engineering team from 25 to 40. We’re looking for product-minded engineers to join us as we continue to scale! We’re looking for someone who thrives on ownership, drives results, and cares deeply about both technical excellence and customer impact.

Return | REMOTE | DevOps / Platform engineer | Full-time
Return (https://return.energy) is hiring a DevOps engineer who will build and run the infrastructure behind platforms that accelerate the transition to carbon-free energy. Return's main activity is building and operating industrial-size Battery Energy Storage Systems. Our operations are located in the Netherlands, Germany, Belgium, and Spain. You will be making a measurable (country-level) impact on the transition to renewable energy. Return recently raised €300M to support its growth.
While we employ over 120 people, Return's technical team is still small (15 people). Our platform automates processes in energy storage, monitoring, market optimization, sales, project management, procurement, construction, and customer service. Behind it sits a mix of EU cloud and on-site compute at our battery sites, with strict uptime and security requirements.
During the first four years of operation, we laid the foundation for our platforms, and we are ready to scale up. This is why we are looking for an experienced DevOps engineer who can own the full picture: cloud environments, self-hosted infrastructure at our BESS sites, and the operations centers in Amsterdam and Eindhoven from which we run the fleet.
Your primary focus will be to design, automate, and operate the infrastructure that our virtual battery platform runs on. That means EU-only cloud providers for application workloads, hardened on-premise setups at our sites, and the connectivity in between. You will be the person who decides what gets deployed where, and who makes sure it stays up and stays secure.

This is a senior role that spans both sides of the platform: backend work in Symfony/PHP, and ownership of the Linux + Ansible automation underneath. You'll be the person making sure the whole thing keeps humming as we scale.
We're a small team with high ownership and very little bureaucracy — if you like shipping over slide decks, you'll fit in.
Remote is fine as long as you can overlap with CET, or you're welcome to join us in Brussels.

Tandem Health | Software Engineers | On-site in Stockholm, Sweden | Full time
At Tandem Health we're building a clinician copilot to allow clinicians to focus on care rather than administration. We’re building, launching and iterating quickly, and are already rolling out across some of the largest care chains across Europe, including most of the NHS.
Our first product listens in to the patient-clinician encounter to generate medical records, allowing clinicians to save 5-10 minutes per patient. No longer do clinicians have to catch up on administration after hours.
We’re expanding our Stockholm team with exceptional builders in a wide range of roles.

Join (https://join.build) | Staff Software Engineer | Remote | $175K–$205K + equity Join builds collaboration software for the construction industry — helping contractors, owners, and architects coordinate on high-value projects. React, Golang, Postgres. We deploy to AWS via Terraform.
We're hiring multiple staff engineers across a range of profiles: frontend-heavy, fullstack, and backend-heavy. We're especially looking for 1–2 engineers with architect-level frontend chops (React, TypeScript, state management, perf) who can own UI quality and level up the team. But we're also very interested in strong Go/Postgres or infra/ops backgrounds.
Day to day you'll write code (25–75%), review PRs (25–50%), and pair/mentor/document (10–20%). You'll act as a technical lead on projects, break down large efforts, and influence architectural decisions across the org. Small cross-functional teams with a designer, PM, and EM.
Stack: React, TypeScript, Golang, Postgres, GraphQL/Apollo, Vite, Cypress, Terraform, AWS (ECS, RDS, Lambda). We lightly use Elastic and are interested in event-driven patterns.
Fully remote, 100% employer-paid medical, 401(k), two company-wide shutdown weeks, continuing education budget.
To apply: send resume to jon@join.build. If you are able to please include a PR review you've given that had a positive impact (or a description/snippet if that's confidential).
Loophole Labs | Senior Systems Engineer | REMOTE (Americas & Europe) | $150k–195k USD + equity | Go, Zig, Rust, C, eBPF, CRIU, Kubernetes
We make Architect: a Kubernetes runtime that hibernates idle pods in place and wakes them in 50ms with TCP connections intact. Five engineers. You'd be the 6th.
If tracing an x86 instruction in the morning and hunting a control-plane race in the afternoon both sound fun, and you insist on measuring rather than guessing, this is the job.
Customers run Architect for workloads where cold starts hurt: real-time voice & video AI agents, long-warming JVM apps, stateful data services that can't be rescheduled cheaply. 1.0 shipped Q1 2026; you'd join mid-way through 2.0. Seed-stage, VC-funded, a few years of runway. Fully distributed across the Americas and Europe.
What you'd work on:
- Hibernation surface: containerd shims and CRUISE, our Zig-native CRIU replacement.
- Control plane: per-node DaemonSet streaming checkpoints; admission controller resizing hibernated pods in place.
- Networking and migration: eBPF/XDP at line rate; cross-node live migration to production; cross-cloud next.
You're a senior generalist. Years across the stack: assembly to frontends, hardware-near, comfortable in x86. Tests ship with the code, decisions get worked out in writing, and you measure rather than guess. Strong in Go; willing to use Zig, Rust, or C.
Bonus: eBPF/XDP, CRIU, Linux kernel internals, containerd, gVisor, live migration, or public writing in kernel/container/eBPF land. Strong systems depth and the willingness to pick up the rest is enough on its own.
Apply: https://loopholelabs.io/careers - we respond within the week (typically a few days).

Y Combinator | Product Engineers on YC's own team | San Francisco | Full Time | $185K-$485K
I'm Ryan, an EM and engineer here at YC. We have a small, 18-person software team with no PMs -- engineers own everything end-to-end.
We build the software behind YC's $6B in investments: tools that help partners evaluate thousands of startups per batch, AI-powered apps that founders use every day, and platforms like Work at a Startup that connect candidates with YC companies. Engineers get unlimited AI tokens -- both for development and to build AI-powered products. What wouldn't you build to help founders + YC with that much firepower?
What makes this different from other roles:
* You'd learn more about startups here than you could possibly imagine. Every batch brings hundreds of founders building things across every industry, and you're right in the middle of it.
* We attend Demo Day, founder dinners, and work directly with partners and many of the companies. (They make great products!)
* We pay well, offer carry in the fund (like equity), and provide generous relocation support if you're not in SF yet.
Two roles open:
* Product Engineer -- full-stack, own the product lifecycle. Rails/React stack. Build tools that power how YC invests in and supports startups. It's a wide range, and sometimes it feels like labs-like work, other times it feels like a supersuit to power founders and our Partners like Garry and Jared.
* Community Builder and Software Engineer -- hybrid role. Run YC's talent-facing programs (meetups, tech talks, career expos) AND build the software that makes them scale. You need to be a great engineer and LOVE to build and support communities.
We're also exploring a Technical Chief of Staff role to work with one of our GPs -- someone who can think analytically, drive operations, and scale what they do with software.
Checkout more about the roles, and email me directly if you're excited to learn more about startups than you will anywhere else - ryan@ycombinator.com

CoPlane (https://coplane.com/) | Product Engineer | NYC (preferred) or Remote (North America) | Full Time
The world doesn't need another ERP. CoPlane is building the Agentic Orchestration platform that enables enterprises to orchestrate intelligent processes across their existing systems. Founded by ex-Stripe/Segment product and tech leads, we're changing how businesses operate their backoffice - helping them scale intelligence not headcount.
We're looking for an exceptional product engineer to grow our small team of engineers that include ex-founders, open source contributors (authors of neovim and neverthrow), and architects of petabyte-scale data platforms.
We are looking for someone that wants to own product features end to end (Python + Typescript/React) but is particularly spiky on frontend and UI. You'll build a platform for billion-dollar enterprises solving their hardest, most mission-critical automation problems.
If you're excited about working at the nexus of data, automation and AI, and want to make a significant impact in an early, well-capitalized startup with large enterprise design partners, we'd love to hear from you.
Roles: Product Engineer.

Fortech Engineering | Full Stack Software Engineer | Primarily remote (Waterloo region, Canada) | $140-170K CAD + performance pay + earned equity
Electrical and mechanical engineering consulting firm in Waterloo, serving the Canadian building construction industry — a market that's still mostly designed the old way. I designed the original platform schema and UX vision; my early code attempts got abandoned when running and growing the firm took priority. The years since have been spent figuring out how to scale this properly and fill those gaps. We're now at the depth and size to support a real build — with no committee in the way, and with my time properly committed to it this time. I'm hiring an exceptional software engineer to take it to the production platform it was always meant to be.
Real users, direct collaboration with the founder, and 20 years of MEP practice plus the platform vision. Few founders building automation in this space bring both.
Profitable, bootstrapped, 18 years old. Equity is earned, not granted — a real cut of a real business, not options in something that may or may not happen.
Stack: TypeScript, React, Tailwind, shadcn/ui, AG Grid, TanStack Query, Drizzle, PostgreSQL, Python (FastAPI), Node.js, Docker.
Looking for: full-stack, agentic-first as a daily working mode, shipper not writer.
Apply: jacri@fortecheng.com More: https://fortecheng.com/careers

We’re building out our team in the following areas:
* Product Software Engineering (Quantitative Modeling)
* Program Synthesis Engineering
* Applied Category Theory Research
* Bayesian Software Engineering
* Finance Operations (Accounting, Analytics & Workforce)
We're also looking for Domain Experts to collaborate on high-value use cases -- identifying and validating opportunities, shaping them into working solutions with our engineers, and taking them from pilot to production with real users. Practitioners with expertise in Valuation Models, Quantitative Default-Probability Models, or Interest Rate Prediction Models are particularly relevant right now.

Kanary | Full Stack Engineer | Remote (US) | Competitive Salary + Equity | Python / React
Kanary is a personal security platform that monitors the web to identify and reduce risk based on an individual's threat model. An executive has different exposure than a gamer, and our system classifies each person's risk across 55,000+ sources. We've been building since 2020, started in campaign security, data science, and government agencies, backed by Mozilla and Y Combinator. We have 200+ organizations on the platform and are fully funded by our customers.
Attackers have never had better tools. LLMs, social media, and search surface personal data in new ways. A few prompts can launch a deepfake and impersonation campaign. Risk sources appear and disappear across social platforms, telegram chats, and private data broker platforms. Kanary exists to play the cat and mouse game for people at the speed and scale of an agentic internet.
Kanary is a combination of software workflows (crawling, scraping, automation), AI (data classification, research, code generation), and people (analysts trained to support customers and escalate). This is dynamic system and requires an interest in adversarial programming.
We’re growing our team, and seeking a multifaceted engineer (2+ years experience). Our software stack is python, javascript, react, and for LLMs, we use Anthropic, OpenAI, and experiment with model fine tuning as needed. Experience with web scraping, data pipelines, or security tooling is required.
Email steven@kanary.com with something you've built and why it was hard.

Level 12 | Full Stack Web Developer - Python, JavaScript, SQL | Mid-Level & Senior | REMOTE | SALARY:$95K-145K+ | https://www.level12.io/careers/
Level 12 is a software consulting and custom development agency. We have mid and senior level positions. Our job descriptions are written by developers for developers. No HR fluff here, we want you to know what you are really getting into:
https://www.level12.io/careers/
- We have a commitment to transparency and offer a "no surprises experience" throughout the interview and hiring process. We value candor...as evidenced by the length of our job description. :)
- Our CEO prefers the title CED, Chief Executive Developer. Engineering and operational concerns don't take a back seat when potential sales come to the front door.

SpruceID (YC W21) | REMOTE (US-Based Preferred) | Full-Time | spruceid.com
Spruce lets users control their data across the web. Instead of users logging into platforms, we believe platforms should request to access data vaults controlled by users.
The demand for trusted digital ID is accelerating as AI deepfakes begin to destroy most of the ways we use to verify identity today. How private or secure is it to hold your driver's license or passport up to a webcam to get a bank account? Was it ever private or secure? Stable diffusion can break so much of this already. Society will need trusted digital IDs and credentials. Our mission is to allow them to be controlled by individuals, with safeguards to prevent descents into surveillance states and checkpoint societies.
We are the main implementers of category-defining initiatives such as the digital ID program for the California DMV, and the verifiable digital credentials program in Utah. We are private sector participants in NIST's National Cyber Security of Excellence initiative for privacy-preserving digital ID.
We are hiring skilled engineers who care about making a real impact in improving public services, digital autonomy, and user privacy for the world. We work closely with public sector agencies, and have high regard for public servants. We have a strong engineering and customer-oriented culture, and are not simply a SaaS product or AI wrapper. Our roles are not for the faint of heart: you will be expected to work hard and learn a lot in this role.
Our engineers are ambitious to get outcomes for our customers and their constituents. On any given day, they may write great Rust/C#/TypeScript, deal with mainframe dumps, read policy documents, respond to technical RFIs/RFPs, manage on-prem environments, implement new NFC + Bluetooth protocols in Swift/Kotlin, create CI/CD processes that enforce W3C accessibility guidelines and i18n requirements, rewrite lost specs from disassembled binaries, figure out stablecoin payments, and design new protections for public key infrastructure. It is a team effort, and people with T-shirt shaped skills are able to collaborate and learn a ton from each other every day.
We are interested in candidates who want to be proud of the meaningful impact they make for society, even if it takes time to get right. This is not the right job for someone who wants to "join a cool new AI startup" that implodes or exits in under a year.

Fastly | Software Engineers (Senior, Staff, Principal) | REMOTE (US, UK, EU) or ONSITE | Full-time
When you look at the headers of major websites, you’ll see us. If it has to be performant, secure, scaled worldwide, and always-on, it uses Fastly.
We're a globally edge cloud platform for performance and security, emphasizing open standards, sustainable engineering, and resilience-by-design. We're hiring across compute, security, platform engineering, network and edge protocols, release engineering, network architecture, client services engineering, and more.
Rather than building walled gardens, we co-founded the Bytecode Alliance, heavily upstream our work to open standards, actively author IETF drafts, and power the global infrastructure for open-source Python, Rust, Ruby, OpenStreetMap, and much more.
* The Stack: Rust, C/C++, Go, Javascript, Typescript, WebAssembly (Wasm/WASI), Wasmtime, Cranelift, eBPF/XDP, QUIC, HTTP, TLS, TCP, Varnish/VCL, Linux kernel internals, distributed systems, professional services.

QUIC, but TCP experience and not UDP? Sorry, being a little pedantic but it's a real question.
Hi! We're Ontix. We're building the business layer to connect siloed datasets and query them with natural language, offering insights to SMBs they couldn't get before. We're fully funded by our sibling company, and are looking for remote freelancers in the US and full-time, onsite employees in San Diego, California (if you're into that kind of thing). We're looking for experience in the following roles:
+ QA: We're looking for a QA engineer deeply familiar with the software lifecycle in the age of agentic coding. You'd have a lot of responsibility, but also the opportunity to define what solid QA looks like at Ontix.
+ Azure Cloud Engineer: We're a mostly-AWS shop, but we have a few potential customers that are deeply entrenched in the Azure ecosystem, including a migration from SharePoint to Fabric + OneLake. You'd be leading the charge on that.
+ Infosec + Automated Vulnerability Scanning: If you browse new CVEs over breakfast, we want to talk to you. There's a huge demand among our current customers for continuous vulnerability scanning, both in the codebase and on the deployed edge. We have some test platforms, but would love a more robust solution we can market.
+ Full-Stack WordPress Developer: Our sister company is a bit old school still: If you can parachute in to a PHP + Vue 2/3 + WordPress + AWS EC2 environment, we would love to pass on your number to them.
We're looking to grow quickly as our client base expands. Healthcare, vision, and 401(k) for FTEs. If you're interested in any of these roles, or would like more information in general about us, please visit https://ontix.io or email l33t@ontix.io with a few sentences describing your experience, interest, and where you're located.
Deep Core Technology | Founding Engineer | REMOTE (CANADA) | Full Time | Salary: $105,000 - $125,000 CAD + 1% equity
Company: We’re building a geologic modelling software, based on reasoning, to help mining and mineral exploration companies work faster. Our goal is to create a way to enable open-ended, interpretive geologic problem solving to be done programmatically, changing the way to explore for hard rock and critical minerals. Currently in active fundraising.
Role: You are the founding engineer on the team, joining co-founder (Neil, CEO) and myself (Jeff, CTO) as first employee. You’ll have a deep influence over systems and architecture. You will have ownership through the entire stack from the database, through geostatistical backend services, through 3D rendering on the client side.
Work rooted in agentic systems, so an understanding of the internals of things like Claude Code, and a broader understanding of orchestrating agents to complete complex discrete tasks is important.
You:
- Fluent in Typescript, Python, and framework/tooling agnostic (Currently using things like NextJS, Supabase, Cesium)
- Eager to learn about mining domain knowledge around the software.
- Ownership of the codebase, and the systems that support the software (project management, CI/CD, monitoring, etc.)
- Open to doing a yearly month abroad with Neil and I. Last year, it was Oaxaca, Mexico.

BIT Capital | Principal Engineer (Data & Platform) | Berlin, Germany | ONSITE (2 days/week) | Full-time
Looking for experienced engineers to build and scale infrastructure and data platforms for a Berlin asset management fund. We are betting big on AI to drive investment returns and build the best infrastructure to support our high alpha targets (track record >30% p.a. since inception; https://bitcap.com/en/bit-global-technology-opportunities-ai...).
You'll design large-scale data pipelines, evolve our lakehouse architecture, strengthen data quality and observability, and build infrastructure for AI/LLM workflows (agentic scaffolding, RAG, LLMOps, AI for engineering). We are looking for a hands-on technical leader, that is steering initiatives end-to-end while staying deep in implementation.
We have our roots in tech entrepreneurship (Jan Beckers), and this mindset still dominates our work culture, even as a regulated financial institution. We are a team of ~40 with a flat hierarchy, hands-on leadership, fast-paced decisions, and a little nerdy culture as people are actually passionate about their work. Stack: AWS, Databricks/Spark, Python, PostgreSQL, Agentic AI.
If the complexity of financial markets excites you as much as the complexity of distributed systems, you'll love it here. Competitive comp, relocation & visa support, stellar team.

Burnin (London or NYC) | Founding Research Scientist + Founding Engineering Lead | Hybrid (Some on-site) | Full-time
We are building the trust stack for AI code generation, targeted at high-stakes computing where wrong numbers cost real money: a statically typed functional language designed for coding models, a compiler whose guarantees double as audit-grade trust infrastructure, and a coding model fine-tuned on the language with compiler fitness as the training signal. Language and model are co-designed.
Small team out of PyTorch, FAIR, and Meta. Strong institutional VC support from our pre-seed; active investor interest heading into seed.
Founding Research Scientist: own the agenda across the language and the model. Type system design, compiler analyses that produce useful fitness gradients, and fine-tuning open-weight coding models on a language with no pretraining footprint. Publish in PL and ML venues. Strongest fits cross between machine learning, programming languages, and formal methods. PhD preferred, equivalent output equally fine. Stack is Rust, Lean 4, Python.
Founding Engineering Lead: own engineering across compiler internals, language runtime, GPU backends, notebook and library tooling, and the AI infrastructure around training, evaluation, model release, and likely public inference. We already support x86 and ARM, CUDA and AMD, macOS and Linux, and the matrix grows. Real feel for statically typed functional programming expected; the kind of engineer who picks up Lean or Haskell on a weekend because they wanted to. Have led engineering before, formally or not. Stack is mostly Rust with Python where it earns its place, primarily on AWS.
Both roles: comfortable with early-stage ambiguity, define your own roadmap, defend it with evidence.

MiLaboratories | Senior Software Engineer (Biologic Discovery) | Bilbao, Spain | ONSITE | VISA | RELOCATION
MiXCR is the standard for immune analysis, cited in thousands of papers. Platforma is the OS on top — bioinformatics as self-serve, interoperable "blocks" for biologic discovery.
5 of the top 10 pharma (Moderna, Pfizer, others) run discovery with Platforma today. Goal: 10 of 10 by year-end. Hiring 4–5 engineers in 90 days. Our tools are in the methods of approved cancer immunotherapies and COVID vaccines reaching millions. The next paper citing us could be the next drug.
We merged frontend, bioinformatics, and data into one team. AI killed the silo wall. Bioinformaticians who leaned into engineering and engineers who leaned into biology now ship at multiples.
WHAT YOU'D BUILD
- Discovery pipelines: raw sequences → pre-IND leads. Antibodies, biomarkers, workflows real scientists use.
- The SDK for comp scientists: TypeScript, Tengo (a Lua-like workflow DSL — yes, you'll learn it), Rust.
- The data layer: thousands of formats reduced to one. PFrames, Parquet, DataFusion, lazy columnar everything.
WHAT WE'RE LOOKING FOR
- Strong TS in 100k-line monorepos (pnpm, Turbo). Polars > pandas. Node ≥22.
- Bioinformatics exposure or appetite to learn it month one. We can teach VDJ recombination; not curiosity.
- Tolerance for sparse docs and niche DSLs. "Fix the SDK, don't work around it."
OFFER
- €90–120k base, real ESOP, ARR-tied bonus — when we grow, you grow, in cash, this year.
- Bizkaia Special Impatriate Regime: ~15–20% effective tax. Beats London / Berlin / Amsterdam net.
- Visa, relocation, soft-landing. No HR, no take-homes. Direct line to engineering.
- Bilbao: ocean, mountains, Michelin, low cost of living, highest quality of life. Onsite — context-sharing needs same room.
Email: stanp@milaboratories.com (CEO). Subject "HN", include GitHub. I reply personally. Tell me about a scientific CLI you wrapped, a plugin SDK you built, or a Polars query that survived 50M rows.

You will discover your gaps quickly and then you get to close them. You will have real access and real responsibility. Your decisions will have meaningful impact on other people's lives. Some people struggle with that. You can't. You will own things. You will learn things. We will build things.
I am six interviews deep into candidates reading me AWS product pages after being asked about their approach to enrichment. If you have ever debugged something in production and have an opinion about literally anything, please talk to me. If you're interested: resume to eng.hiring@sonarmd.com.
If you're really interested: send a cover letter in .md format (no AI, I will know) with answers to: - Last 3 things you personally shipped to prod, preferably ones that failed or had unexpected results - Most recent thing you learned but are too embarrassed to admit you didn't already know - Your 3 biggest pain points working with AI/LLMs/agents - Most recent thing you built that you're legitimately proud of - Preferred tech stack - How many full, 8-hour-day, 5-day-a-week production shipping years you got under your belt, for real

Shepherd | ONSITE | San Francisco, CA
At Shepherd, we're pursuing the most ambitious technical vision in commercial insurance: fully autonomous underwriting. Shepherd is an AI-native commercial insurance platform transforming how high-hazard industries get covered.
The infrastructure behind the AI boom (data centers, semiconductor fabs, renewable energy assets) has to be built and insured, but traditional carriers weren't built for this speed. We built Shepherd to solve that.
We just recently announced our $42M Series B! That brings our total funding to over $60M — led by Intact Private Capital, the investment arm of one of the largest insurers in the world. Intact is not only our lead investor but also a carrier partner, a testament to the confidence the incumbent industry has in what we're building.
