AMD | Rust, Compiler, and Systems Engineer, Senior or Staff | San Jose, CA | ONSITE | Full-time
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.
Brightcore Energy | Senior Embedded Software/Hardware Engineer | Brooklyn, NY (hybrid, 3 days/week onsite) | Full-time | $140k-$170k+ base, flexible for the right experience, plus annual bonus
Brightcore Energy designs, builds, and operates clean energy systems, geothermal, solar, and building energy efficiency, for commercial and institutional buildings. A growing share of our work is managing geothermal cooling assets at data centers.
We're hiring an owner for Brightcore EDGE, an on-prem industrial PC that runs our control and optimization algorithms directly at customer sites, including data center facilities where real-time energy management is mission-critical. You'd select and harden the industrial PC and Linux platform, build the imaging, provisioning, and fleet-update process, integrate with building management systems over BACnet and Modbus (Schneider Electric, Johnson Controls, Honeywell, Siemens), build the local time-series data logging and telemetry pipeline, and implement OS hardening, disk encryption, and network segmentation to satisfy OT security reviews at high-security sites.
Reports directly to our VP of Innovation. Looking for 5-8+ years in embedded systems, industrial controls, or edge/IoT, strong Linux, Python and/or C/C++, and some BACnet/Modbus background. It's a high-ownership, spec-it-and-build-it role, you'll be buying hardware and shipping working prototypes without a lot of process overhead.

Unitary Foundation | Member of Technical Staff, Fault Tolerant Quantum Compilation + Simulations | REMOTE (US) | Full-time
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.com | Senior Backend Engineer, Scanning Infrastructure | REMOTE: North America / Europe, UTC-8 to UTC+2 | Full-time
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.
