I'm looking for a strong compiler and systems generalist to join me at AMD in San Jose.
This role is for someone who enjoys moving across abstraction layers and solving difficult, open-ended engineering problems. Relevant experience may include LLVM, MLIR, compiler frontends or backends, intermediate representations, optimization and code generation, language runtimes, Rust or C++, low-level GPU systems, firmware, program analysis, or formal methods.
Rust is central to the role. We are investing in Rust for low-level systems where performance, control, and correctness all matter, and this person will help make that investment successful. You should be excited to write substantial production Rust and to improve the compiler, tooling, interfaces, and engineering practices around it. Deep Rust experience is valuable, but a strong compiler or C++ systems engineer who is serious about becoming highly effective in Rust can also be a good fit.
You do not need experience in every area. Strong fundamentals, sound technical judgment, and the ability to become productive in unfamiliar parts of a large systems stack matter more than matching a fixed list of technologies. We value people who can connect architecture to implementation, build rigorous tests, and communicate clearly about correctness and tradeoffs.
This is a full-time, onsite position in San Jose, California. To learn more, email me directly at harsh.menon@amd.com with "HN" in the subject. Please include a short introduction and a resume or links to relevant work.

Unitary Foundation is a 501(c)(3) non-profit research group building a quantum technology ecosystem that benefits the most people. We build open-source infrastructure for quantum computing — current projects include Mitiq, UCC, and Clifft — and run community programs like microgrants and unitaryHACK.
We're hiring an MTS to help define and build our open-source compilation and simulation stack: compilation, simulation, error mitigation, resource estimation, benchmarking, and early fault-tolerant workflows. You'll join a small technical team doing research through sponsored collaborations with national labs, universities, and industry partners. The role is about technical ownership — forming a technical point of view, proposing roadmaps, and building tools that become useful shared infrastructure. There's also room to experiment thoughtfully with AI-assisted research workflows.
We're looking for a track record of building software other people use (ideally open source), a strong background in quantum computing (fault tolerance, error correction, compilation, simulation), and strong Python; C++/Rust is a plus. A PhD is one possible background for this role, but not required.
Lokker is a privacy platform that helps organizations understand and control what is happening across public-facing infrastructure: websites, browser-side applications, scripts, pixels, cookies, tags, forms, SDK/API calls, and browser-side data flows.
We are hiring a senior backend engineer to own and continue to scale Lokker’s scanning infrastructure. This role focuses on backend systems for high-volume website scanning, browser automation, distributed scanning, networking, reliability, performance, and cost optimization.
IMPORTANT: A key requirement for this role is substantial, hands-on production experience with browser automation, headless browsers, crawlers, scanners, synthetic monitoring, scraping infrastructure, or closely related technologies. This is not a general backend role, and we can only consider candidates who have already built, operated, or scaled systems in this domain.
Other relevant experience includes distributed systems, queues/orchestration, high-scale backend services, HTTP/TLS/DNS, proxies, CDNs, WAFs, bot detection, and fingerprinting.
Production experience in Go, Rust, TypeScript/Node.js, C++, or similar.

Aqora Quantum is building the algorithm layer of quantum computing: the place where people develop, share, and orchestrate quantum workflows. Hardware gets most of the attention, but the algorithms and the tooling around them are where the field actually becomes useful, and today that work is scattered across notebooks and one-off scripts. We host versioned datasets and reproducible benchmarks so results are comparable, and give teams a way to publish a workflow that someone else can pick up and run. Think Kaggle/Hugging Face, but for quantum. We're a small but growing team, having just raised our seed round, and we're now extending into the US.
We're looking for one senior full-stack engineer. You'd own features end to end: GraphQL API and services in Rust, React/TypeScript frontend, plus the runner that executes user-submitted workflows against simulators and real backends.
You don't need a quantum background, but you do need to enjoy going deep on an unfamiliar technology and getting productive in it fast. That happens here constantly, and we'll give you the time and the people to learn it properly. Beyond that: production Rust you've shipped and maintained, and real comfort across the stack.
Onsite in Paris or remote anywhere in the EU. If you're not in Paris, expect to join us there regularly for team weeks.
Email jannes@aqora.io with a CV or GitHub, mention HN. Happy to answer questions in the thread too.
Hi HN,
I’m the founder of Proxybase [0]. We’re building an agentic SOCKS5 proxy network designed to bring transparency and ethical sourcing to the residential proxy market.
Quick note to anyone who applied last month: First off, thank you to everyone who reached out. We got hit with way more high-quality applications than expected, and between running day-to-day operations and working through the backlog, we took much longer to respond than we should have. If you applied last month and haven't heard back, we're genuinely sorry for the delay, we are actively reviewing those responses alongside this batch.
Why Proxybase? Historically, the residential proxy industry has been pretty shady, think hidden background scrapers bundled into TV firmware or mobile apps, combined with predatory payout systems that hold provider funds hostage for months.
We’re taking a different approach:
Fully Open-Source Clients: Our GUI [1] and CLI [2] are completely open-source so anyone can inspect and audit what we run. Explicit Consent: Providers knowingly opt in. No stealth bundling. Instant, Fair Payouts: $1 minimum payout threshold sent directly to provider wallets via US stablecoins—no holding funds to farm interest.
What We’re Looking For We’re looking for a Backend Systems Engineer (Rust) to help us build out our asynchronous SOCKS5 routing infrastructure, daemon node orchestration, and automated bandwidth allocation pipelines.
Stack: Rust (Tokio / Axum), SOCKS5 protocol, Linux systemd daemons, SQLite Location: Fully Remote (Async-friendly, flexible timezone) Compensation: Competitive salary + equity (USD or stablecoin options available)
If you're interested in building infrastructure for an industry that desperately needs better standards, send an email to jobs@proxybase.xyz with your GitHub/resume and a short note on what you’ve been working on lately.
I’m also around in the comments if you have any questions or feedback on what we're building.
Canopy builds the real-time coordination layer for hospitals: communication, safety, location intelligence, and response across large, complex care environments. Every hospital is a logistics problem wrapped around a clinical one, with millions of people and events an hour across the country. When a building can sense itself in real time, the gap between an event and the right person arriving goes from minutes to seconds. People are safer, care arrives faster, and hospitals and clinics get a path to modernize on the infrastructure they already run. Sensing is the foundation.
You'd build our next-generation sensing and ML pipeline (the "physical full stack"), from sensors and embedded firmware through edge algorithms to the backend and frontend services. Physics-based modeling for sensing problems that traditional IoT products can't solve, in devices that have to survive harsh environments. We care deeply about hardware-in-the-loop platforms, simulations, and internal tools. Ideal candidates have shipped production features on both sides of the hardware/software line.
What we've deployed recently: TypeScript, WASM, Rust, C, Python, RTOS (Zephyr, FreeRTOS), embedded Linux.
If you care about the difference between 99.99% and 99.999%, and about the frontline medical staff relying on that last nine, you'll like it here.
Apply: https://job-boards.greenhouse.io/canopyworks/jobs/4317128009 AND email hn <at> (company domain) about a real-world sensor that broke your prior assumptions: what you expected, what the data actually did, and what you changed.

We maintain physical offices in Austin, San Francisco, New York City, Seattle, Los Angeles, and Chicago in the U.S., and in Gurugram (Delhi) and Bengaluru in India. If you’re located near one of these offices, we would love for you to spend time in the office regularly. Some roles are hybrid or in-office by design. For example, our engineering team in India works primarily from our Gurugram office.
We’re a small, high-impact team solving one of the most interesting and adversarial problems in fintech: how do you build systems that reliably determine whether a real human is on the other side of a financial transaction? We’re hiring across Engineering (Full-stack and Infra) and Data Science / ML roles. Hiring at Manager/Director level as well as mid-level/Senior levels. We’re language-agnostic and hire for fundamentals.
Across the team you’ll see: • Python, Go, Rust, Scala • PostgreSQL, Snowflake • Kafka, Redis • Terraform, Kubernetes • ML: XGBoost, PyTorch, Feature stores, real-time scoring pipelines
If you love solving complex distributed systems challenges, building customer-facing ML products, or working on detection systems that must be both high-precision and low-latency, you’ll fit right in.

We’re looking for passionate individuals for whom programming is not just a job, but something they genuinely love to do. We’re obsessed with computers, programming, big data, databases, compilers, hardware, math, data science, and the internet. Does this sound like you? Please apply to join our team.
Our codebase is friendly to new contributors. You’ll have a fully functional development environment within hours through full automation and will be pushing commits on your first day. Deployments to production happen multiple times per day and finish in under two minutes.Effectively all of our codebase is written in Python, Rust, SQL, JavaScript/TypeScript, and Nix. The core technologies you’ll need familiarity with to be productive are Python, PostgreSQL, Linux, and Git.
We operate at a larger scale than typical startups. We run two datacenters with high-performance servers we’ve built ourselves, capable of handling the volumes of data we process. We’ve implemented our own distributed file system, perform full-scale web crawls, and download and run static analysis on the entire universe of published Android APKs and iOS IPAs.
Unlike a typical startup where you might spend half your time in meetings and the other half fixing Jira tickets, at MixRank you’ll challenge yourself with difficult technical problems that help you grow as an individual. We’re continuously hiring for the positions below; these aren’t singular roles that close once filled. Our philosophy is that the candidate is more important than the position. For each new member of the team, we design a custom role and responsibilities around their interests. Other companies may create a long list of specific requirements with the expectation that you’ll exactly replace someone on the team or fit a role defined by committee. MixRank is more pragmatic: we first get excited about bringing a unique individual onto the team, then figure out the best way to support their specific talents.
