We're a team of 9 (6 in engineering) with one Account Executive, and we're looking for up to three more with a focus on German-speaking countries (DE, AT, CH), but open if you think you can enter other European markets for us.
Stream | Multiple Positions | Amsterdam (NL), Skopje (North Macedonia) | Boulder, CO (US) | Toronto (Canada)) | Remote possible | Full Time | Visa Sponsorship | https://getstream.io
Stream powers Chat, Video, AI Moderation, and Activity Feeds for billions of global end users across thousands of different apps.
We're constantly hiring backend engineers, but I wanted to take this opportunity to tout my own hire because I'm hoping you'll come work with me... I'm pavlov on HN, been here for nearly two decades, and working in realtime media for a good while longer. Now I run the Video team at Stream and I'm looking for a Staff Engineer. You'd report to me with a direct line to our CTO. Check out the details:
You'd own the media plane of Stream Video. It's a modern stack: SFU in Go, cascading to handle very large audiences, ingest and recording fleets, global multi-cloud edge. Video is fundamentally different from request-based services, which means this is not just a seat in Stream's shared infra team, but a genuine Staff role with its own roadmap defined by you. You can email me directly at pauli.ojala@getstream.io, happy to connect and tell you more.
Full-time role, hybrid with 3 days a week in our Amsterdam office, or remote from anywhere in the EU. Visa sponsorship for the Netherlands.
Namespace | San Francisco, CA / New York, NY / Zurich, Switzerland / Remote | Full-time | REMOTE or HYBRID | https://namespace.so
Namespace is a vertically integrated infrastructure stack for software development. We build everything ourselves, from the server racks to the hypervisor and scheduler, and we run it globally.
Teams at SpaceXAI, Ramp, Sierra, Fal, Vanta, Framer, ElevenLabs, and many others build their software on Namespace today.
Open roles (all full-time, global, remote & hybrid):
Better Stack | https://betterstack.com/ | /^Full-?stack Engineer$/i | Remote (North America & Europe)
We are software builders at :heart: CEO is a software engineer, COO is a software engineer, and you guessed it, CTO is an engineer, too. We are engineers, making the tools we always wanted. If you love building amazing software, you're at the right address.
We are looking for software engineers who, given enough time, could build Better Stack on their own = looking for full-stack product engineer generalists to help us create high-quality software with exceptional UX, end-to-end.
Pond AI | Head of Engineering (founding-level) | San Francisco | Onsite | Full-time | https://joinpond.ai
Most non-tech businesses know exactly which workflows they want AI agents to handle, but have no one to build, connect and run them. Pond delivers custom AI agents to these businesses through a network of 7k AI builders, with Pond as the platform and security layer over MCP.
We're backed by Tier-1 VCs and a co-inventor of GPT, and we're looking for a hands-on technical leader to own the platform end to end.
You'd be a great fit if you:
- Build full-stack and ship AI agents in production (TypeScript/Python, LLMs, tool use)
- Have worked on payments, agent coordination/MCP, or platform/marketplace products
- Have early-stage startup experience (founder, founding or early engineer) and like to grind
Email dylan@joinpond.ai with something you've built.
humans& | Product Engineer (Member of Technical Staff) | San Francisco | ONSITE | Full-time
humans& is a human-centric frontier AI lab. Our view is that AI should help people work together, so it has to understand people and the relationships between them, not just tasks.
Last month we launched Boba (https://boba.app), an assistant you can text one-on-one or add to a group chat. It runs on Ampersand, our first model, trained with RL over millions of simulated days with thousands of simulated people. Boba keeps track of your goals for weeks or months, sets up reminders and calendar invites, uses email and searches the web. In a group chat it reads social context and decides when to speak up and when to stay quiet. Early users have sent it more than a million messages.
Looking for product engineers who have done exceptional work on how humans and computers interact. You’ll build the product side of this: new interaction patterns for an AI that lives in group chats, remembers people and acts for them.
The founding team comes from xAI, Google DeepMind, OpenAI, Stanford and MIT. Our investors include NVIDIA, GV and SV Angel.
Juro | AI Engineer (Agentic team) | London, UK | REMOTE (UK) | Full-time | £115k + equity
Juro is an AI contract automation platform used by in-house legal and business teams. Our Agentic team builds Operator, the agent that works across contracts inside Juro: it answers questions and takes action on legal data. You'd build the tools that let it act across the product, own parts of the agent harness (planning, tool use, context) and put evals around what you ship, together with our QA team.
Stack: TypeScript/Node.js, MongoDB, pgvector, AWS Bedrock, LiteLLM, Mastra, some React. Engineers pick their own AI tooling (Claude Code, Codex, Cursor...) and we pay for the usage.
We're looking for programmers first who now build with LLMs, and who have shipped something people use. Years of ML matter less to us than what you've built. We apply models, we don't train them.
Process: 30-min intro call, interview with the hiring manager, a build review where you walk us through something you've built, and a short chat with our CTO. We reply to every applicant.
You'll work from the UK. For exceptional candidates we can sponsor a UK Skilled Worker visa, whether you're relocating or already in the UK. If you need sponsorship, say so in your application.
Equall is an AI-native platform for corporate legal work in private markets. We extract and reconcile legal information from source documents (charters, SPAs, board consents) and produce auditable outputs: cap table tie-outs, governance dashboards, personnel summaries. Law firms use us to do due diligence in hours instead of weeks. Working with leading ECVC firms now, expanding into PE and M&A.
The role: own the knowledge graph at the core of the platform. Design the public APIs, build the Prefect pipelines that turn documents into structured graph data, run it in production on Kubernetes.
Mastra is the open-source TypeScript framework for building AI agents (agents, workflows, memory, evals, tracing). From the team behind Gatsby, YC-backed, https://github.com/mastra-ai/mastra
Why: Four months ago Mastra was a very popular open-source agent framework with very little monetization. Then we launched our platform, and now we're closing a couple of deals a week. Pipeline is growing faster than one person can work it, so this is our second dedicated sales hire. You start day 1 with a warm pipe: most leads are already using the open-source framework.
What you'd sell: Platform (Studio, Server, infra to run/debug/observe agents in production, hosted or self-hosted for regulated orgs), Agent Builder (agents without code), and Concierge (embedded Mastra engineers working alongside customer teams). Full-cycle, mid-market: Series A–C, often with regulatory or infra constraints, sales cycles of a few weeks, talking to eng leaders.
You have: Closed full-cycle deals in dev tools, OSS, infra, or AI. Enough technical depth to come across as a smart PM with engineers: understand their use cases and scope a solution. Founder or founder mentality. Comfort with a product that ships something new every week.
Backed by Sequoia Capital, Peregrine is the operational AI platform powering decision making and operations SF / NYC / DC | In-office 4 days | $175,000 - $300,000
Tandem Health | Engineers, Designers, PMs | On-site in Stockholm, Sweden | Full time
At Tandem Health we're building the AI-native operating system for clinics, so clinicians can focus on care rather than administration. We're building, launching and iterating quickly, and already support more than 10,000 care organisations across 14 European markets, including most of the NHS. We recently raised a $100M Series B to go further, faster.
It started with our AI medical scribe, which listens in to the patient-clinician encounter to generate medical records and saves clinicians 5-10 minutes per patient. Today our AI medical assistant supports clinicians before, during and after each visit, with medical coding and clinical decision support, three products certified as medical devices under EU MDR.
We're expanding our Stockholm team with exceptionally driven builders in a wide range of roles.
SwingVision | Berkeley, CA | Full time + Internships
SwingVision uses computer vision to turn a single phone camera into an automated stats, highlights, and line-calling system for tennis, pickleball, and padel. Models run on-device in real time, and the app won an Apple Design Award for Innovation. We're growing the ML and product teams.
We make robots that autonomously construct buildings, starting with bricklaying.
There's a lot of vapourware in robotics, but we're deploying robots across multiple concurrent sites today - and generating revenue. In the last couple of months, our robots have built affordable social housing, health care living units, canal walls in the historic city centre of Amsterdam, and a youth sports centre. Help us to build things that matter in the long run.
We're looking for experienced software engineers for many roles. You can help us solve problems like:
- Data sync and analytics queries across a fleet of robots (that can be offline for hours at a time)
- Modelling buildings in code and finding the right UI for operators to edit them
- Designing systems for robots to drive safely and fully autonomously around a building site
We're rapidly scaling up operations - we're already hiring operators in the UK too - and we need experienced engineers who can build the systems that manage all of that complexity. If you think that 'full-stack' could reasonably mean debugging firmware, mixing buckets of mortar _and_ writing React components, we are looking for you. Robotics experience not required!
Stratirus (a Tennetech company) | AI Developer + Linux Admin (junior to mid) | REMOTE (US only, Central Time hours) | US work authorization required, no sponsorship | Full-time or part-time, contract or hire | $65k to $100k | No agencies
Our optional take-home is a broken Ubuntu server: a service that won't stay up, a nightly report that hasn't gone out in days, and a disk that keeps filling. Fix it, write a script that heals a fresh box, and build a small read-only MCP tool so an AI agent can check on it. 60 to 90 minutes, unpaid, no LeetCode. If that sounds like fun, read on.
We're a small and growing AI and Microsoft 365 consultancy in Franklin, TN. We build AI agents and automation for small and mid-sized businesses, and harden and run the systems underneath: Microsoft 365 tenants, SharePoint, and Linux boxes. We're AI-agnostic and use what fits the client, mostly Claude Code, the Microsoft 365 stack with Copilot and Copilot Studio, Gemini and Gemini Studio, and Oracle OBI. The role is about 60% agent development (MCP servers, Claude Code, Copilot Studio, Power Automate, Gemini) and 40% Ubuntu administration (systemd, Docker, patching, backups, monitoring). PeopleSoft experience is a plus. You'll work directly with clients, so explaining things clearly to a small-business owner matters as much as the code. Early-career and career-switchers welcome.
We expect you to use AI every day. What we hire for is knowing when it's wrong, so one of our three application questions asks about a time it fooled you.
To apply, email your resume to hiring@stratirus.com with short answers to: a time a client or boss made an unreasonable demand and how you handled it; a time an AI confidently gave you a wrong answer you followed, and how you caught it; and something you've built with AI that you still use. Work samples get strong preference. We read every application ourselves and reply to everyone, so please write your answers yourself.
Process: email application, a 45-minute video call where you walk us through something you've built, then a conversation about the role.
Remote within the US only, Central Time business hours. Must be legally authorized to work in the US without visa sponsorship, now or in the future. No recruiters or agencies, please.

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 announced our $42M Series B earlier this year! 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.
We’re looking for product-minded, high ownership engineers to join our team! The Engineering team is HQ’d in SF, but we’re growing in NYC now too!
We’re hiring for 2 Senior SWEs, 1 MLE and 1 AI PM in SF, and 2 Staff SWEs in NYC. Engineers own projects end-to-end so full stack ability is expected.
Check out our open roles here: https://shepherdinsurance.com/careers
Our stack includes: Typescript, React, Next.js, GraphQL w/ Apollo, Node.js, Postgres & Redis
– If you have experience building AI agents or multi-step reasoning systems, we’d love to hear from you.
* In the form, be sure to mention that you heard about this opportunity via Hacker News.

Simple Analytics | DevOps Engineer | REMOTE (worldwide, any timezone) | Full-time, 32h, 24h possible | €5,000/month (full-time) | https://www.simpleanalytics.com/jobs/devops
Hi HN, I'm Adriaan. Simple Analytics exists thanks to HN: it started with my Show HN in 2018 [1]. Today we're a self-funded, profitable team of four building privacy-first analytics.
Privacy is why we run our own bare-metal servers instead of the cloud. We're preparing for a LOT more traffic, and you'll own the infrastructure and its reliability. We have good documentation. First project: leading the infra side of our Elasticsearch to ClickHouse migration, with Alex, our developer.
Stack: Ansible, OpenTofu, Docker Compose, Grafana, GitHub Actions, TypeScript. Clear async communication matters more than knowing every tool.
When you say "Full-time, 32h, 24h possible | €5,000/month (full-time)" is the €5,000/month salary pegged at 40h/week so that the actual payment is scaled up/down based on the number of hours worked per week?

Kraus Hamdani Aerospace | Software Engineer | REMOTE (US) or ONSITE in Reno, NV
We build long-endurance autonomous aircraft and the software used to operate them.
Looking for a strong generalist software engineer. Most application work is TypeScript/web, with C/C++ and Rust elsewhere in the stack. You’ll work across frontend, backend, cloud, DevOps, and directly with flight test and hardware teams.
We care a lot about code quality, maintainability, and engineers who can take ambiguous problems and independently ship solid software. No sloppers.
We The Flywheel | Remote | Brand Identity Designer (AI-agent team) | Hourly, flexible hours
We build and run our own brands (race finders, training tools, AI guides, sports media) with a small remote team and a lot of AI agents.
Most of our brands have an identity that is good enough. We want someone with a sharp eye to make them good: logo refinements, lockups, favicons, social and OG images, colour and type rules. It's polish and judgment, not starting from scratch. Our agents do the digging, so you spend your time designing.
Bridge AI Consulting | AI Consultant, Junior AI Consultant | REMOTE (US) | Full-time | $60K–$100K base + upside for new business, equity possible | Visa sponsorship possible
We're a small, bootstrapped, profitable AI consulting firm. We embed with small and mid-size businesses (wealth management, real estate, construction, higher ed, nonprofits), learn how the work actually gets done, build what makes sense (mostly Claude: skills, agents, connectors, MCP) and train every person until they don't need us. We went from 1 client in February to about 20.
You'd own client relationships end to end: discovery, the build, the training. Strong builders who can also explain things to a 60-year-old business owner do very well here.

Synteq | Growth Lead & Systems Administrator | Austin, TX | REMOTE (US) | Full-time
Synteq is a developer cloud running our own hardware and network. We do large-scale bare-metal, GPU, VPS, storage, and PaaS deployments across 5 US datacenters.
- Growth Lead: own top of funnel for a developer cloud product, covering SEO, community, PLG, and partnerships. Open to people new to growth or with some experience. https://synteq.com/career/growth-lead
We build AI agents that run revenue for short-term rental and hotel operators on Booking.com and Airbnb: live prices, promotions and visibility on real portfolios, plus an MCP connector so customers work their accounts from Claude and ChatGPT.
Our engineers no longer type most of the code. Claude Code and Codex do. The hard part is knowing what to build, how it should fit together, and whether what the agent wrote is actually right. You will talk to customers, own the architecture, write the briefs, and catch what the agent missed.
We do not care which language you know.
We care that you can do architecture (single source of truth, clear boundaries, the right layer for a fix) and that you already ship this way.
Big bonus if you have worked on hotels, short-term rentals or dynamic pricing.
Small team, paying customers, hard problems (private OTA APIs, PMS integrations, pricing decisions that move real money). Three interview stages, no take-home. Email me (CTO) directly: martin@mydatavalue.com
8 years ago, Jeremy was absolutely frustrated with the status quo of data infrastructure in manufacturing. Companies paid millions per year for "shitty 90s software" and are still doing that today, when there is much better software out there for open-source. So we decided that we can do this better, first founded a System Integrator, realized most of the tasks in setting up and maintaining a data infrastructure can be standardized, and decided to found the currently VC-backed UMH, which is built on open source software and is open source itself.
What we're actually building: We build and scale a real-time data platform that runs hundreds of Benthos pipelines inside a single Docker container (UMH Core), processing millions of industrial messages that control actual production processes.
Plus a local-first user interface (Management Console) where both non-technical factory workers and power-users/developers can work together. And yes, we care about UI in enterprise/industrial software.
We're preparing a U.S. Department of Education SBIR Phase IA proposal to build an assessment reasoning platform for school speech-language pathologists. It implements TTL-MSM, a fully specified decision framework for one of the hardest calls in school eligibility evaluations: whether a student's communication profile reflects a disorder or a difference. Clinicians code each source of evidence, and a fixed rule combines them. The rules are written; the software isn't. The research lead is at Baylor University.
Prototype Developer ($70–95/hr): build a browser-based web app from a written spec, with privacy designed in from the start so it's ready for FERPA-protected student data later. About 15–20 hrs/week for nine months if funded.
Technical Product Lead ($75–100/hr): the bridge between the clinical spec and the engineering. Scope the prototype, turn the spec into requirements, and keep the build on schedule. About 5–8 hrs/week for nine months if funded.
Pre-award scoping (10–15 hrs for the developer, 5–10 for the lead) is unpaid, and funded work is contingent on award. U.S. citizens or permanent residents.
Apply (structured application, about 30 minutes; replies within five business days):

University of Cambridge, University of Manchester | PhD in AI / Earth Observation / Environmental Science | ONSITE | UK home fee status only | £30k tax-free annual stipend
Our group at Cambridge works on Earth Observation foundation models (Tessera: v1 https://arxiv.org/abs/2506.20380, v2 https://arxiv.org/abs/2607.03949, https://geotessera.org/) and we've started a collaboration with Manchester to understand how they can be used to improve pollution models and then environmental decision making in general. This involves training new models and doing high-resolution inference across national or even global scales, as well as figuring out how to use that data to help policymakers make better decisions.
As part of this work we have a PhD studentship through the joint Manchester-Cambridge Centre for Doctoral Training for AI in Decision Making for Complex Systems. This involves one year at Manchester doing taught postgraduate study and then three years at Cambridge for the PhD.
Our work is all open source and involves solving significant compute and data challenges. Training our current-generation model takes ~250k GPU hours and a single year of global inference needs to move over 5.5 petabytes of data through the inference pipeline. This project would suit someone with strong machine learning and software engineering experience. We can help you build the atmospheric science and Earth Observation skills.

Pond AI | Head of Engineering (founding-level) | San Francisco | Onsite | Full-time | https://joinpond.ai
Most non-tech businesses know exactly which workflows they want AI agents to handle, but have no one to build, connect and run them. Pond delivers custom AI agents to these businesses through a network of 7k AI builders, with Pond as the platform and security layer over MCP.
We're backed by Tier-1 VCs and a co-inventor of GPT, and we're looking for a hands-on technical leader to own the platform end to end.
You'd be a great fit if you:
- Build full-stack and ship AI agents in production (TypeScript/Python, LLMs, tool use)
- Have worked on payments, agent coordination/MCP, or platform/marketplace products
- Have early-stage startup experience (founder, founding or early engineer) and like to grind
Email dylan@joinpond.ai with something you've built.
humans& | Product Engineer (Member of Technical Staff) | San Francisco | ONSITE | Full-time
humans& is a human-centric frontier AI lab. Our view is that AI should help people work together, so it has to understand people and the relationships between them, not just tasks.
Last month we launched Boba (https://boba.app), an assistant you can text one-on-one or add to a group chat. It runs on Ampersand, our first model, trained with RL over millions of simulated days with thousands of simulated people. Boba keeps track of your goals for weeks or months, sets up reminders and calendar invites, uses email and searches the web. In a group chat it reads social context and decides when to speak up and when to stay quiet. Early users have sent it more than a million messages.
Looking for product engineers who have done exceptional work on how humans and computers interact. You’ll build the product side of this: new interaction patterns for an AI that lives in group chats, remembers people and acts for them.
The founding team comes from xAI, Google DeepMind, OpenAI, Stanford and MIT. Our investors include NVIDIA, GV and SV Angel.
Apply: https://humansand.ai/
Juro | AI Engineer (Agentic team) | London, UK | REMOTE (UK) | Full-time | £115k + equity
Juro is an AI contract automation platform used by in-house legal and business teams. Our Agentic team builds Operator, the agent that works across contracts inside Juro: it answers questions and takes action on legal data. You'd build the tools that let it act across the product, own parts of the agent harness (planning, tool use, context) and put evals around what you ship, together with our QA team.
Stack: TypeScript/Node.js, MongoDB, pgvector, AWS Bedrock, LiteLLM, Mastra, some React. Engineers pick their own AI tooling (Claude Code, Codex, Cursor...) and we pay for the usage.
We're looking for programmers first who now build with LLMs, and who have shipped something people use. Years of ML matter less to us than what you've built. We apply models, we don't train them.
Process: 30-min intro call, interview with the hiring manager, a build review where you walk us through something you've built, and a short chat with our CTO. We reply to every applicant.
You'll work from the UK. For exceptional candidates we can sponsor a UK Skilled Worker visa, whether you're relocating or already in the UK. If you need sponsorship, say so in your application.

Equall is an AI-native platform for corporate legal work in private markets. We extract and reconcile legal information from source documents (charters, SPAs, board consents) and produce auditable outputs: cap table tie-outs, governance dashboards, personnel summaries. Law firms use us to do due diligence in hours instead of weeks. Working with leading ECVC firms now, expanding into PE and M&A.
The role: own the knowledge graph at the core of the platform. Design the public APIs, build the Prefect pipelines that turn documents into structured graph data, run it in production on Kubernetes.
Stack: Python, Prefect, Postgres, Redis, Kubernetes.
Need: production backend experience (Python, Go, Rust, or Zig), data pipelines at scale, strong views on API design, comfort on k8s.
Bonus: built a graph DB, designed workflow orchestration, integrated LLM workflows into backend infra, Kafka.
Apply: https://jobs.ashbyhq.com/equall/48013ed1-8fab-4b49-b926-6d7e... and mention HN.
Mastra | Founding Sales (Founding AE) | US Remote | Full-time
Mastra is the open-source TypeScript framework for building AI agents (agents, workflows, memory, evals, tracing). From the team behind Gatsby, YC-backed, https://github.com/mastra-ai/mastra
Why: Four months ago Mastra was a very popular open-source agent framework with very little monetization. Then we launched our platform, and now we're closing a couple of deals a week. Pipeline is growing faster than one person can work it, so this is our second dedicated sales hire. You start day 1 with a warm pipe: most leads are already using the open-source framework.
What you'd sell: Platform (Studio, Server, infra to run/debug/observe agents in production, hosted or self-hosted for regulated orgs), Agent Builder (agents without code), and Concierge (embedded Mastra engineers working alongside customer teams). Full-cycle, mid-market: Series A–C, often with regulatory or infra constraints, sales cycles of a few weeks, talking to eng leaders.
You have: Closed full-cycle deals in dev tools, OSS, infra, or AI. Enough technical depth to come across as a smart PM with engineers: understand their use cases and scope a solution. Founder or founder mentality. Comfort with a product that ships something new every week.
Apply: { https://jobs.ashbyhq.com/Mastra/d5fe8d36-843a-4f9b-9d65-779e... } We get back to everyone.

Tandem Health | Engineers, Designers, PMs | On-site in Stockholm, Sweden | Full time
At Tandem Health we're building the AI-native operating system for clinics, so clinicians can focus on care rather than administration. We're building, launching and iterating quickly, and already support more than 10,000 care organisations across 14 European markets, including most of the NHS. We recently raised a $100M Series B to go further, faster.
It started with our AI medical scribe, which listens in to the patient-clinician encounter to generate medical records and saves clinicians 5-10 minutes per patient. Today our AI medical assistant supports clinicians before, during and after each visit, with medical coding and clinical decision support, three products certified as medical devices under EU MDR.
We're expanding our Stockholm team with exceptionally driven builders in a wide range of roles.

MONUMENTAL | https://www.monumental.co/ | Amsterdam, The Netherlands | Full Time | Onsite
We make robots that autonomously construct buildings, starting with bricklaying.
There's a lot of vapourware in robotics, but we're deploying robots across multiple concurrent sites today - and generating revenue. In the last couple of months, our robots have built affordable social housing, health care living units, canal walls in the historic city centre of Amsterdam, and a youth sports centre. Help us to build things that matter in the long run.
We're looking for experienced software engineers for many roles. You can help us solve problems like:
- Data sync and analytics queries across a fleet of robots (that can be offline for hours at a time)
- Modelling buildings in code and finding the right UI for operators to edit them
- Designing systems for robots to drive safely and fully autonomously around a building site
Check out the progress we've already made on Atrium, our operating system for robotics: https://www.monumental.co/atrium
We're rapidly scaling up operations - we're already hiring operators in the UK too - and we need experienced engineers who can build the systems that manage all of that complexity. If you think that 'full-stack' could reasonably mean debugging firmware, mixing buckets of mortar _and_ writing React components, we are looking for you. Robotics experience not required!

Stratirus (a Tennetech company) | AI Developer + Linux Admin (junior to mid) | REMOTE (US only, Central Time hours) | US work authorization required, no sponsorship | Full-time or part-time, contract or hire | $65k to $100k | No agencies
Our optional take-home is a broken Ubuntu server: a service that won't stay up, a nightly report that hasn't gone out in days, and a disk that keeps filling. Fix it, write a script that heals a fresh box, and build a small read-only MCP tool so an AI agent can check on it. 60 to 90 minutes, unpaid, no LeetCode. If that sounds like fun, read on.
We're a small and growing AI and Microsoft 365 consultancy in Franklin, TN. We build AI agents and automation for small and mid-sized businesses, and harden and run the systems underneath: Microsoft 365 tenants, SharePoint, and Linux boxes. We're AI-agnostic and use what fits the client, mostly Claude Code, the Microsoft 365 stack with Copilot and Copilot Studio, Gemini and Gemini Studio, and Oracle OBI. The role is about 60% agent development (MCP servers, Claude Code, Copilot Studio, Power Automate, Gemini) and 40% Ubuntu administration (systemd, Docker, patching, backups, monitoring). PeopleSoft experience is a plus. You'll work directly with clients, so explaining things clearly to a small-business owner matters as much as the code. Early-career and career-switchers welcome.
We expect you to use AI every day. What we hire for is knowing when it's wrong, so one of our three application questions asks about a time it fooled you.
To apply, email your resume to hiring@stratirus.com with short answers to: a time a client or boss made an unreasonable demand and how you handled it; a time an AI confidently gave you a wrong answer you followed, and how you caught it; and something you've built with AI that you still use. Work samples get strong preference. We read every application ourselves and reply to everyone, so please write your answers yourself.
Process: email application, a 45-minute video call where you walk us through something you've built, then a conversation about the role.
Remote within the US only, Central Time business hours. Must be legally authorized to work in the US without visa sponsorship, now or in the future. No recruiters or agencies, please.

Shepherd (Series B) | 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 announced our $42M Series B earlier this year! 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.
We’re looking for product-minded, high ownership engineers to join our team! The Engineering team is HQ’d in SF, but we’re growing in NYC now too!
We’re hiring for 2 Senior SWEs, 1 MLE and 1 AI PM in SF, and 2 Staff SWEs in NYC. Engineers own projects end-to-end so full stack ability is expected.
Check out our open roles here: https://shepherdinsurance.com/careers Our stack includes: Typescript, React, Next.js, GraphQL w/ Apollo, Node.js, Postgres & Redis – If you have experience building AI agents or multi-step reasoning systems, we’d love to hear from you.

Hi HN, I'm Adriaan. Simple Analytics exists thanks to HN: it started with my Show HN in 2018 [1]. Today we're a self-funded, profitable team of four building privacy-first analytics.
Privacy is why we run our own bare-metal servers instead of the cloud. We're preparing for a LOT more traffic, and you'll own the infrastructure and its reliability. We have good documentation. First project: leading the infra side of our Elasticsearch to ClickHouse migration, with Alex, our developer.
Stack: Ansible, OpenTofu, Docker Compose, Grafana, GitHub Actions, TypeScript. Clear async communication matters more than knowing every tool.
You can apply from your terminal:

When you say "Full-time, 32h, 24h possible | €5,000/month (full-time)" is the €5,000/month salary pegged at 40h/week so that the actual payment is scaled up/down based on the number of hours worked per week?

Most of our brands have an identity that is good enough. We want someone with a sharp eye to make them good: logo refinements, lockups, favicons, social and OG images, colour and type rules. It's polish and judgment, not starting from scratch. Our agents do the digging, so you spend your time designing.
Please include identity work that is live somewhere. There's a short assessment, read by a person. https://wetheflywheel.com/en/careers/brand-product-designer/...

We went from 1 client in February to about 20.
You'd own client relationships end to end: discovery, the build, the training. Strong builders who can also explain things to a 60-year-old business owner do very well here.

myDataValue | Founding Product Engineer | London (Canary Wharf) | HYBRID, 2 days/week in office | up to £90k + up to 1% equity | https://www.mydatavalue.com/founding-product-engineer/
We build AI agents that run revenue for short-term rental and hotel operators on Booking.com and Airbnb: live prices, promotions and visibility on real portfolios, plus an MCP connector so customers work their accounts from Claude and ChatGPT.
Our engineers no longer type most of the code. Claude Code and Codex do. The hard part is knowing what to build, how it should fit together, and whether what the agent wrote is actually right. You will talk to customers, own the architecture, write the briefs, and catch what the agent missed.
We do not care which language you know.
We care that you can do architecture (single source of truth, clear boundaries, the right layer for a fix) and that you already ship this way.
Big bonus if you have worked on hotels, short-term rentals or dynamic pricing.
Small team, paying customers, hard problems (private OTA APIs, PMS integrations, pricing decisions that move real money). Three interview stages, no take-home. Email me (CTO) directly: martin@mydatavalue.com
Cologne, Germany | UMH | Product Engineer | Full-time | 70k - 100k EUR | ONSITE (part remote)
Hi, Alex and Jeremy here from UMH.
8 years ago, Jeremy was absolutely frustrated with the status quo of data infrastructure in manufacturing. Companies paid millions per year for "shitty 90s software" and are still doing that today, when there is much better software out there for open-source. So we decided that we can do this better, first founded a System Integrator, realized most of the tasks in setting up and maintaining a data infrastructure can be standardized, and decided to found the currently VC-backed UMH, which is built on open source software and is open source itself.
What we're actually building: We build and scale a real-time data platform that runs hundreds of Benthos pipelines inside a single Docker container (UMH Core), processing millions of industrial messages that control actual production processes.
Plus a local-first user interface (Management Console) where both non-technical factory workers and power-users/developers can work together. And yes, we care about UI in enterprise/industrial software.

ORFF Maestra | Prototype Developer; Technical Product Lead | REMOTE (US only) | Contract, part-time | https://orffmaestra.com
We're preparing a U.S. Department of Education SBIR Phase IA proposal to build an assessment reasoning platform for school speech-language pathologists. It implements TTL-MSM, a fully specified decision framework for one of the hardest calls in school eligibility evaluations: whether a student's communication profile reflects a disorder or a difference. Clinicians code each source of evidence, and a fixed rule combines them. The rules are written; the software isn't. The research lead is at Baylor University.
Prototype Developer ($70–95/hr): build a browser-based web app from a written spec, with privacy designed in from the start so it's ready for FERPA-protected student data later. About 15–20 hrs/week for nine months if funded.
Technical Product Lead ($75–100/hr): the bridge between the clinical spec and the engineering. Scope the prototype, turn the spec into requirements, and keep the build on schedule. About 5–8 hrs/week for nine months if funded.
Pre-award scoping (10–15 hrs for the developer, 5–10 for the lead) is unpaid, and funded work is contingent on award. U.S. citizens or permanent residents.

University of Cambridge, University of Manchester | PhD in AI / Earth Observation / Environmental Science | ONSITE | UK home fee status only | £30k tax-free annual stipend
Our group at Cambridge works on Earth Observation foundation models (Tessera: v1 https://arxiv.org/abs/2506.20380, v2 https://arxiv.org/abs/2607.03949, https://geotessera.org/) and we've started a collaboration with Manchester to understand how they can be used to improve pollution models and then environmental decision making in general. This involves training new models and doing high-resolution inference across national or even global scales, as well as figuring out how to use that data to help policymakers make better decisions.
As part of this work we have a PhD studentship through the joint Manchester-Cambridge Centre for Doctoral Training for AI in Decision Making for Complex Systems. This involves one year at Manchester doing taught postgraduate study and then three years at Cambridge for the PhD.
Our work is all open source and involves solving significant compute and data challenges. Training our current-generation model takes ~250k GPU hours and a single year of global inference needs to move over 5.5 petabytes of data through the inference pipeline. This project would suit someone with strong machine learning and software engineering experience. We can help you build the atmospheric science and Earth Observation skills.
We are a highly collaborative group who spend our time not only on foundational research but also on developing applications with practitioners and decision makers. Our work sees use in many industrial, academic and government environments for problems like crop classification, tree species mapping and change detection.
You can find out more here: https://www.findaphd.com/phds/project/from-satellite-to-stre... - if you have questions about the project you can contact me, Sadiq Jaffer, at sj514@cam.ac.uk . For questions about the application process you'll want aidecisionscdt@manchester.ac.uk .
Application deadline is Friday 4th of December with a course start date of September 2027.
