Spade | Multiple Engineering, AI/ML Data Science, and Revenue Roles | ONSITE NYC or REMOTE (US/Can) | $170-240K + equity
Spade is the data and AI platform for modern finance. We take messy transaction data and turn it into structured, verified records — with a platform, models, and tooling that help our customers use it everywhere it matters.
We're looking for extraordinary builders to play a foundational role in a company designed for scale:
We're well-funded by top investors (YC/a16z/OAK), and known for building intentional, inclusive culture. We offer competitive compensation (salary + equity) and comprehensive benefits.
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 hiring for the following openings:
* Engineering Program Lead
* Backend Software Engineer
* Quantitative Modelling Engineer
* Bayesian Software Engineer
* Program Synthesis Engineer
* Analytic Learning Algorithm Researcher
* Product Managers and Business Development
* Domain Experts - Valuation, Quantitative Default-Probability, or Interest Rate Prediction Models: to collaborate on use cases, from opportunity validation through production
We’ve recently released a series of recordings from one of our quarterly team retreats, to share a look into how we work, and some of the technical problems we’re solving. A few team members sat down and talked through these topics, unscripted, and real. If you consider applying to join us, they offer a glimpse into our culture, and what working with us is really like. Watch the series on YouTube » https://www.youtube.com/@plantingspace9225/videos
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 global 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.
Onsite preferred, but remote candidates with a strong fit are welcome!
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.

Renaissance Philanthropy | Research Engineer (Speech AI/ML) | Remote (worldwide)
Renaissance Philanthropy's aim is to activate a virtuous circle of increasing ambition and impact between philanthropists and innovators: by identifying frontier experts both in science and in new ways of solving problems; by tapping into the growing number of emerging philanthropists; and by building multi-sector initiatives that can harness the power of philanthropy, markets, and governments.
RenPhil's Engineering Hub supports mission-driven, grant-funded educational technology projects that seek to improve educational outcomes in fundamental skills like math and reading. This summer we're launching a program called LEVI Literacy, which has a goal of halving the number of struggling readers in the US within 5 years.
We're looking for an expert in modern voice AI to support this work. Our partner teams are building tools that assess and support early reading directly from children's speech in real classrooms — oral reading, spoken vocabulary tasks, whole-class instruction. These are hard, meaningful speech problems: young children's voices, noisy multi-speaker environments, and high stakes for getting it right — and fair — for every student.
We're looking for folks who:
- have built and operated production ASR or speech-processing systems
- know the full data-to-model pipeline: collection, annotation, fine-tuning, evaluation, and deployment
- can speak the languages of both research and engineering
- want to help create a world where all children learn to read well.
G-Research is a leading quant finance company. Big compute farm, interesting problems.
My team is hiring senior engineers to work on our (actually world class) DAG scheduling infra for distributing research and production workloads across the compute farm. What we do is roughly:
* maintain and improve the SDKs for that scheduler in Python, F#, and C#
* add interesting new features to the scheduler itself
* maintain and improve a web backend and UI for quants and engineers to monitor their jobs, increasingly with high availability requirements
* translate bidirectionally at the business level between low-level infra providers and quant/ML researchers
Some functional experience preferred, because our core product is in F#. Lots of dealing with very smart researchers and engineers, with the kind of fun problems arising when you run large ML workloads at scale.

Noricum | Senior Backend Engineer, Payments, Ledger & Provable Fairness | REMOTE (2h overlap with US Pacific) | Contract to permanent | $120-160/hr | Start by 14 Sep
I'm the founder of Noricum where we build platforms – currently the money infrastructure, ledger, engine and payment rails behind a pre-launch wagering platform with a Steam skins economy. The games, a cashier and a bet ledger are built and live as a front end, with written specs for the server contract: ledger schema, refusal table, round lifecycle, every game's arithmetic. Processing and licensing are secured. The server does not exist. That is the job. You would own:
- A server-authoritative game engine - seeds, nonces, outcome computation
- A double-entry ledger where balance is derived and no client write can change it
- Server-side enforcement of every limit and refusal
- Payment rails idempotent under duplicated webhooks
- Seed custody and the provably-fair lifecycle
- An affiliate system with referral attribution and commission payouts
Must have shipped: a double-entry ledger or equivalent money system in production, a payment integration including webhook idempotency, auth and sessions you built and operated, and infrastructure you owned end to end. Provably-fair systems, settlement-side gaming or trading infra, or Steam trade automation all stand out.
Email michael@noricum.io with your start date and a few lines on the last money system you shipped - what it guaranteed, and how you knew it held.
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 4 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.

I’m a co-founder of Quill, a fullstack SDK for adding customer-facing analytics & data features to your app. Backed by YCombinator & top-tier SV-based investors (fundraising not publicly disclosed; happy to share any details when we chat).
Some examples of how customers get value from Quill:
• pre-IPO fintech adds custom reporting & data export features to their money movement product.
• Series B healthtech is now able to deliver completely custom in-product reports & dashboards to every enterprise customer they onboard.
• Series A govtech adds analytics and reporting capabilities within their existing agent/chat product.
Reasons you’d love working with us:
• Work with a small, focused, talented team on a highly technical product (by developers for developers).
• Funded company in a big market, but still prelaunch with a team size <5
• High level of product ownership with tight feedback loops: the products you build are shipped quickly and get used by real customers immediately. Our latest hire built our entire CLI product from 0 -> 1, and it was used in production by customers the day it shipped.
We are growing the team to keep up with demand for new features that our customers are asking us for, while also preparing for launch. We're looking for someone that will make us better. We’re just getting started, and want you to bring your opinions, expertise, and experience to the table (not just execute on the ideas we already have).

Rust developer/software engineer at NLnet foundation in Amsterdam
You will join the team responsible for the development and operation of the (Rust based) backend through which we administer our open source grant programmes, and which integrates with our website.
About us: Fancy ETL pipeline which processes products from huge ecommerce companies. Data extraction and massage, delivery to destinations like Google/Meta/TikTok/etc. Profitable, 18+ yrs stable, 100% employee-owned. No VC, no pointless meetings, just serious coding.
You: 5+ yr senior dev who's seen (and fixed) enough dumpster-fire code to last a lifetime. Python/Django deeply internalized; solid JS skills and able to wrangle Vue/React. You rock backend data pipelines like old jeans: Dagster, Snowflake, DuckDB, Postgres - in the cloud or on your bitchin' VM rack. Docker and Git are second nature. You've embraced agentic coding while still keeping the bots from running the slop show. You play well with others and write code that's easy to live with. Bonus: building AI assistants with PydanticAI, Py2→Py3 migrations, CI/CD and DevOps chops.
Timezones: Primary time zone is PST (standups at 9AM PST). Generally async-friendly but you must reside in the United States and be geographically grounded.
Benefits: 401K match, healthcare/vision/dental, equity, fully remote. Stable company with no time-wasters.

Modash helps brands find, manage, and pay creators - and helps creators earn a living.
The product looks simple on the surface. Underneath, we index 380M+ public creator profiles across Instagram, TikTok, and YouTube so that 1,700+ brands search, evaluate, manage, and pay creators without drowning in spreadsheets and tabs.
We're looking for Senior Product Engineers who like owning ambiguous problems end-to-end. No perfectly shaped tickets. You talk to customers, understand messy workflows, make product decisions, ship, and own whether it actually works.
The problems we care about:
- How do you make a 380M-profile dataset feel fast, trustworthy, and easy to explore?
- How do you turn chaotic influencer marketing workflows into product that feels obvious?
- How do you build tools that work for both small teams and brands like Stanley, Sennheiser, Birkenstock, and NordVPN??
We're 85 people, raised an €11M Series A, and ARR is doubling every year. HQ is in Tallinn, engineering is fully remote across Europe.
No ticket factory. No seven layers of approval. Small teams, real ownership, hard product problems.
Stpkr Technologies is hiring for the following roles to build the next generation of wearable devices.
We are currently looking for the following roles but we are also open to interviewing any candidates who feel like they will do their best work here - even if your skillset/experience doesn't fit the current defined roles. Our current team doesn't fit the conventional mold, and we don't expect our future hires will either. If you don't fit the advertised roles, just send us a mail per the same process with whatever job title would fit you the best.
Work is in person near Noida Sector 18, walking distance from Sector 18 Metro Station. We prefer in office work, and for you to be located within Delhi/NCR, Pay is competitive (9-12 LPA), and there are opportunities to earn meaningful equity down the line. We prefer current and recent undergraduates for our roles. If you are still in college we welcome you to apply nonetheless provided you can work as an intern for us in person. Super-flexible overall and all of our current team started out as interns. We are not flexible on in-office work because of operational requirements - please do not apply if you can't relocate/work from office.
Hiring across OS, software, and hardware. AI policy across all roles: you should be able to do the work without AI, and much faster with it.
Systems Engineer - Everything at the OS layer. You've rooted phones, flashed custom ROMs, broken and fixed Linux for fun. Comfortable in C/C++. GitHub with kernel-adjacent or LineageOS-type projects a plus. Stack: Android, Linux, C, C++, Java. Filter: send us something you built where you had to fight the OS or hardware.
Hardware Engineer - Bring-up/Debug/Integration - Take EVT/DVT boards and make them work. Comfortable with J-Link and IDE debugging, reading schematics and reference designs. KiCad/Altium/EasyEDA hobby work would make you ideal. PetaLinux experience or hunger to learn it. ECE undergrad fine. Filter: photo of a board you designed or debugged, plus what went wrong.
Hardware Engineer - Power/RF/Wireless - Make the power and RF paths behave on EVT/DVT boards. Hands-on with schematic capture, layout, soldering, scope/logic analyzer. Given two unknowns, you pick one and start measuring. Filter: sensor fusion work, how noise behaves across protocols, and SPI debug chops.
Founder's Office - Work closely with the founder and the rest of the team to manage the day to day and long term affairs of the company, the Man Friday of the company. Must have a decent degree of technical knowledge (we are a tech company after all) and be efficient at administrative tasks as well as management. Speed and learning ability are prized here, there will not always be a clear path to the work you have to do here, so you will have to figure some of it out on your own.
To apply, contact arnav@stpkr.in with the subject line "HN - Human" and a brief intro for further communication. Attach any documents you deem useful there. Please include the role you are applying for at the top of the email if it is one of the above mentioned, otherwise whatever role fits you best. Shortlisting will be online, interviews will be in person. We are hiring quickly, expect to hear back from us within 2-3 days of applying. If you don't, assume you will not. If you are using an AI agent to mass apply for jobs and we can tell, then you will not hear back. Use an expensive one :P (reiterating this, because we receive so much AI spam now. Thanks for your time!
Proxybase | Backend Systems Engineer (Rust) | Remote, Global | Full-Time
Hi HN,
I’m the founder of Proxybase [0]. We’re building a SOCKS5 proxy network focused on transparency and ethical sourcing in the residential proxy market.
A quick note for anyone who applied last month: thank you to everyone who reached out. We received far more strong applications than expected, and between running day-to-day operations and working through the backlog, we took much longer to reply than we should have.
If you applied last month and haven’t heard back yet, I’m sorry for the delay. We’re actively reviewing those applications alongside this new batch.
Why Proxybase?
The residential proxy industry has a rough history. Some providers rely on hidden background scrapers bundled into TV firmware or mobile apps, while others use payout systems that can hold provider funds for months.
We’re trying to build something better:
Open-source clients: Our GUI [1] and CLI [2] are fully open source, so anyone can inspect and audit what runs on their device.
Explicit consent: Providers knowingly opt in. No stealth bundling.
Fair, fast payouts: The minimum payout is $1, sent directly to provider wallets in USD stablecoins. We do not hold funds to earn interest on them.
We’re hiring a Backend Systems Engineer with Rust experience to help build:
Stack: Rust, Tokio, Axum, SOCKS5, Linux systemd daemons, SQLite
Location: Fully remote, async-friendly, flexible time zones
Compensation: Competitive salary plus equity. USD or stablecoin payment options are available.
If you’re interested in building infrastructure for an industry that needs better standards, email jobs@proxybase.xyz with your GitHub, résumé, and a short note about what you’ve been working on recently.

We're a remote-first digital product studio building across sports media, AI, fitness, and personal branding — 500+ web properties and deeply AI-native workflows. AI does the heavy lifting here, but it's the leverage, not the point: we hire for the human judgment, ingenuity, and taste on top of it.
Open now:
* Agentic PR Coordinator — media lists, outreach, drafting, and AI-assisted PR workflows for earned media. Entry-level, 10–40 hrs/week.
* Agentic-Led Social Media Marketer — AI-native social media management: content, scheduling, and performance across channels. 10–40 hrs/week.
* Production Designer — brand and marketing asset production using AI tooling. 10–40 hrs/week.
Also open: Agentic Engineer, Sr Agentic Engineer, Agentic Operations Coordinator, Agentic Operator, AI Operator Team Lead, Creative Copywriter & Storyteller, and more.
It would be good to indicate if you are open to engineers in Europe or the UK and what hourly salary they should be expecting. The other locations you list are considerably cheaper and might indicate you aren't paying enough to support talent from these geographies.

Renaissance Philanthropy | Research Engineer (Speech AI/ML) | Remote (worldwide)
Renaissance Philanthropy's aim is to activate a virtuous circle of increasing ambition and impact between philanthropists and innovators: by identifying frontier experts both in science and in new ways of solving problems; by tapping into the growing number of emerging philanthropists; and by building multi-sector initiatives that can harness the power of philanthropy, markets, and governments.
RenPhil's Engineering Hub supports mission-driven, grant-funded educational technology projects that seek to improve educational outcomes in fundamental skills like math and reading. This summer we're launching a program called LEVI Literacy, which has a goal of halving the number of struggling readers in the US within 5 years.
We're looking for an expert in modern voice AI to support this work. Our partner teams are building tools that assess and support early reading directly from children's speech in real classrooms — oral reading, spoken vocabulary tasks, whole-class instruction. These are hard, meaningful speech problems: young children's voices, noisy multi-speaker environments, and high stakes for getting it right — and fair — for every student.
We're looking for folks who:
- have built and operated production ASR or speech-processing systems
- know the full data-to-model pipeline: collection, annotation, fine-tuning, evaluation, and deployment
- can speak the languages of both research and engineering
- want to help create a world where all children learn to read well.

Noricum | Senior Backend Engineer, Payments, Ledger & Provable Fairness | REMOTE (2h overlap with US Pacific) | Contract to permanent | $120-160/hr | Start by 14 Sep
I'm the founder of Noricum where we build platforms – currently the money infrastructure, ledger, engine and payment rails behind a pre-launch wagering platform with a Steam skins economy. The games, a cashier and a bet ledger are built and live as a front end, with written specs for the server contract: ledger schema, refusal table, round lifecycle, every game's arithmetic. Processing and licensing are secured. The server does not exist. That is the job. You would own:
- A server-authoritative game engine - seeds, nonces, outcome computation - A double-entry ledger where balance is derived and no client write can change it - Server-side enforcement of every limit and refusal - Payment rails idempotent under duplicated webhooks - Seed custody and the provably-fair lifecycle - An affiliate system with referral attribution and commission payouts
Must have shipped: a double-entry ledger or equivalent money system in production, a payment integration including webhook idempotency, auth and sessions you built and operated, and infrastructure you owned end to end. Provably-fair systems, settlement-side gaming or trading infra, or Steam trade automation all stand out.
Email michael@noricum.io with your start date and a few lines on the last money system you shipped - what it guaranteed, and how you knew it held.
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 4 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

Quill | Fullstack SWE | Full-time | Remote, PT/ET hours preferred | $150 - 210K USD + equity | https://quill.co/
I’m a co-founder of Quill, a fullstack SDK for adding customer-facing analytics & data features to your app. Backed by YCombinator & top-tier SV-based investors (fundraising not publicly disclosed; happy to share any details when we chat).
Some examples of how customers get value from Quill: • pre-IPO fintech adds custom reporting & data export features to their money movement product. • Series B healthtech is now able to deliver completely custom in-product reports & dashboards to every enterprise customer they onboard. • Series A govtech adds analytics and reporting capabilities within their existing agent/chat product.
Reasons you’d love working with us: • Work with a small, focused, talented team on a highly technical product (by developers for developers). • Funded company in a big market, but still prelaunch with a team size <5 • High level of product ownership with tight feedback loops: the products you build are shipped quickly and get used by real customers immediately. Our latest hire built our entire CLI product from 0 -> 1, and it was used in production by customers the day it shipped.
We are growing the team to keep up with demand for new features that our customers are asking us for, while also preparing for launch. We're looking for someone that will make us better. We’re just getting started, and want you to bring your opinions, expertise, and experience to the table (not just execute on the ideas we already have).

Please normalize 4DWW - Four Day Work Week
Whoever posts this monthly, please include the tag in your description. Employers need to know this is an in-demand feature we want. I for one will not be taking any non-4DWW jobs.
It would also be nice to note if it's 6DWW or 7DWW. I've been told GenZ is very into the these options.
Cerity Partners (https://ceritypartners.com) | Data Engineer | Full Time | Hybrid NYC
We are a RIA looking for an incredibly inquisitive person who enjoys rolling their sleeves up and diving into data. Technology is only part of the role. Working with stakeholders--and understanding what their pain points are--is more important than optimizing a query.

ORIGAMICS | Founding Researcher | San Francisco | ONSITE/REMOTE
Origamics is building AI models that reason about electronics and help turn schematics into production-ready boards.
We’re looking for a Founding Researcher to work directly with the founders on physics-informed models for Electronics design — physical behavior, simulation, and scientific ML. You’ll tackle open-ended research problems, push models from experiments to production and real hardware, and have the opportunity to publish novel research along the way.
You’ll likely be a good fit if you have strong ML/research fundamentals, enjoy 0→1 problems, and have experience with scientific ML, geometric deep learning, numerical methods, simulation, EE, or applied physics. PhD is a plus, not a requirement.
Apply: https://www.origamics.ai/join-us?ashby_jid=7acf3a2d-46a5-420... (Mention HN when applying.)

VersaFeed.com | SENIOR SOFTWARE ENGINEER (Python/Django + JavaScript - VueJS/React) | REMOTE (USA ONLY) | Full-time
About us: Fancy ETL pipeline which processes products from huge ecommerce companies. Data extraction and massage, delivery to destinations like Google/Meta/TikTok/etc. Profitable, 18+ yrs stable, 100% employee-owned. No VC, no pointless meetings, just serious coding.
Stack: Python/Django, JavaScript, VueJS/React, Docker, Git, PostgreSQL/Snowflake/DuckDB, Dagster, AWS + Strong agentic coding skills (Claude Code / Codex)
Compensation: $150K–$220K USD/year DOE.
You: 5+ yr senior dev who's seen (and fixed) enough dumpster-fire code to last a lifetime. Python/Django deeply internalized; solid JS skills and able to wrangle Vue/React. You rock backend data pipelines like old jeans: Dagster, Snowflake, DuckDB, Postgres - in the cloud or on your bitchin' VM rack. Docker and Git are second nature. You've embraced agentic coding while still keeping the bots from running the slop show. You play well with others and write code that's easy to live with. Bonus: building AI assistants with PydanticAI, Py2→Py3 migrations, CI/CD and DevOps chops.
Timezones: Primary time zone is PST (standups at 9AM PST). Generally async-friendly but you must reside in the United States and be geographically grounded.
Benefits: 401K match, healthcare/vision/dental, equity, fully remote. Stable company with no time-wasters.

Modash.io | Senior Product Engineer | Remote (Europe) | Full-time | €75k–110k | https://modash.io
Modash helps brands find, manage, and pay creators - and helps creators earn a living.
The product looks simple on the surface. Underneath, we index 380M+ public creator profiles across Instagram, TikTok, and YouTube so that 1,700+ brands search, evaluate, manage, and pay creators without drowning in spreadsheets and tabs.
We're looking for Senior Product Engineers who like owning ambiguous problems end-to-end. No perfectly shaped tickets. You talk to customers, understand messy workflows, make product decisions, ship, and own whether it actually works.
The problems we care about:
- How do you make a 380M-profile dataset feel fast, trustworthy, and easy to explore?
- How do you turn chaotic influencer marketing workflows into product that feels obvious?
- How do you build tools that work for both small teams and brands like Stanley, Sennheiser, Birkenstock, and NordVPN??
We're 85 people, raised an €11M Series A, and ARR is doubling every year. HQ is in Tallinn, engineering is fully remote across Europe. No ticket factory. No seven layers of approval. Small teams, real ownership, hard product problems.

Moyai Agent Reliability Engineering
Stpkr Technologies | Noida, India (Delhi NCR) | ONSITE | Multiple roles
Stpkr Technologies is hiring for the following roles to build the next generation of wearable devices.
We are currently looking for the following roles but we are also open to interviewing any candidates who feel like they will do their best work here - even if your skillset/experience doesn't fit the current defined roles. Our current team doesn't fit the conventional mold, and we don't expect our future hires will either. If you don't fit the advertised roles, just send us a mail per the same process with whatever job title would fit you the best.
Work is in person near Noida Sector 18, walking distance from Sector 18 Metro Station. We prefer in office work, and for you to be located within Delhi/NCR, Pay is competitive (9-12 LPA), and there are opportunities to earn meaningful equity down the line. We prefer current and recent undergraduates for our roles. If you are still in college we welcome you to apply nonetheless provided you can work as an intern for us in person. Super-flexible overall and all of our current team started out as interns. We are not flexible on in-office work because of operational requirements - please do not apply if you can't relocate/work from office.
Hiring across OS, software, and hardware. AI policy across all roles: you should be able to do the work without AI, and much faster with it.
Systems Engineer - Everything at the OS layer. You've rooted phones, flashed custom ROMs, broken and fixed Linux for fun. Comfortable in C/C++. GitHub with kernel-adjacent or LineageOS-type projects a plus. Stack: Android, Linux, C, C++, Java. Filter: send us something you built where you had to fight the OS or hardware.
Hardware Engineer - Bring-up/Debug/Integration - Take EVT/DVT boards and make them work. Comfortable with J-Link and IDE debugging, reading schematics and reference designs. KiCad/Altium/EasyEDA hobby work would make you ideal. PetaLinux experience or hunger to learn it. ECE undergrad fine. Filter: photo of a board you designed or debugged, plus what went wrong.
Hardware Engineer - Power/RF/Wireless - Make the power and RF paths behave on EVT/DVT boards. Hands-on with schematic capture, layout, soldering, scope/logic analyzer. Given two unknowns, you pick one and start measuring. Filter: sensor fusion work, how noise behaves across protocols, and SPI debug chops.
Founder's Office - Work closely with the founder and the rest of the team to manage the day to day and long term affairs of the company, the Man Friday of the company. Must have a decent degree of technical knowledge (we are a tech company after all) and be efficient at administrative tasks as well as management. Speed and learning ability are prized here, there will not always be a clear path to the work you have to do here, so you will have to figure some of it out on your own.
To apply, contact arnav@stpkr.in with the subject line "HN - Human" and a brief intro for further communication. Attach any documents you deem useful there. Please include the role you are applying for at the top of the email if it is one of the above mentioned, otherwise whatever role fits you best. Shortlisting will be online, interviews will be in person. We are hiring quickly, expect to hear back from us within 2-3 days of applying. If you don't, assume you will not. If you are using an AI agent to mass apply for jobs and we can tell, then you will not hear back. Use an expensive one :P (reiterating this, because we receive so much AI spam now. Thanks for your time!
howdy! This is the "Who's hiring?" post, I believe you're looking for the "Who wants to be hired?" post
Proxybase | Backend Systems Engineer (Rust) | Remote, Global | Full-Time
Hi HN, I’m the founder of Proxybase [0]. We’re building a SOCKS5 proxy network focused on transparency and ethical sourcing in the residential proxy market. A quick note for anyone who applied last month: thank you to everyone who reached out. We received far more strong applications than expected, and between running day-to-day operations and working through the backlog, we took much longer to reply than we should have. If you applied last month and haven’t heard back yet, I’m sorry for the delay. We’re actively reviewing those applications alongside this new batch.
Why Proxybase? The residential proxy industry has a rough history. Some providers rely on hidden background scrapers bundled into TV firmware or mobile apps, while others use payout systems that can hold provider funds for months.
We’re trying to build something better: Open-source clients: Our GUI [1] and CLI [2] are fully open source, so anyone can inspect and audit what runs on their device. Explicit consent: Providers knowingly opt in. No stealth bundling. Fair, fast payouts: The minimum payout is $1, sent directly to provider wallets in USD stablecoins. We do not hold funds to earn interest on them.
We’re hiring a Backend Systems Engineer with Rust experience to help build:
Asynchronous SOCKS5 routing infrastructure, Daemon and node orchestration, Automated bandwidth-allocation pipelines
Stack: Rust, Tokio, Axum, SOCKS5, Linux systemd daemons, SQLite
Location: Fully remote, async-friendly, flexible time zones Compensation: Competitive salary plus equity. USD or stablecoin payment options are available.
If you’re interested in building infrastructure for an industry that needs better standards, email jobs@proxybase.xyz with your GitHub, résumé, and a short note about what you’ve been working on recently.
I’ll also be around in the comments to answer questions and hear feedback.

It would be good to indicate if you are open to engineers in Europe or the UK and what hourly salary they should be expecting. The other locations you list are considerably cheaper and might indicate you aren't paying enough to support talent from these geographies.
