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.
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 Thanks for your 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 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 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.
