Agent guide: [/agents.md](https://www.wearedevelopers.com/agents.md). --- # Firmware Engineer - **Company:** Arc Full-time - **Location:** San Francisco, CA, United States - **Salary:** $112,456.0 - $200,000.0 - **Contract:** Permanent contract - **Skills:** Software Debugging, Firmware, Systems Integration, Hardware Testing - **Published:** August 5, 2026 - **Apply:** https://www.indeed.com/viewjob?jk=96079fa72c13fbef ## About the Role * Experience in Rust programming * Understanding of firmware fundamentals * Ability to learn quickly * Resilience ## Description This role is for a venture-backed hardware startup in San Francisco building high-performance power conversion systems. A new product is coming to market, and this hire owns the software side of it, from the control loops running on the microcontroller through the test infrastructure that proves the hardware works. This is firmware that lives close to the metal. You'll write Rust for parts with tight memory and timing budgets, work against real switching hardware, and debug with a scope as often as a debugger. The bar is high. The ideal person takes ownership and executes, and when they hit a wall they go find the way through it. What you'll do * Write Rust firmware for resource-constrained microcontrollers * Design and validate high-frequency power electronics control loops * Design and bring up the software integration for the hardware test suites * Work on test fixtures for the manufacturing line ## Related Videos - [More efficient software for more efficient microchips](https://www.wearedevelopers.com/videos/1164-more-efficient-software-for-more-efficient-microchips) - [Using AI Without Losing Your Skills](https://www.wearedevelopers.com/videos/2045-using-ai-without-losing-your-skills) - [WeAreDevelopers LIVE - Modern DevOps for IoT Devices and More](https://www.wearedevelopers.com/videos/1805-wearedevelopers-live-modern-devops-for-iot-devices-and-more) - [Playing Pong on a shoulder press machine](https://www.wearedevelopers.com/videos/100140-playing-pong-on-a-shoulder-press-machine) - [Building your way to a serverless powered IOT Buzzwire game](https://www.wearedevelopers.com/videos/590-building-your-way-to-a-serverless-powered-iot-buzzwire-game) - [Agent Smith Gets Hardware: Autonomous IoT Hacking From Debug Port to Cloud API](https://www.wearedevelopers.com/videos/100258-agent-smith-gets-hardware-autonomous-iot-hacking-from-debug-port-to-cloud-api) ## Related Articles - [Dev Digest 121 - AI goes offline](https://www.wearedevelopers.com/magazine/456-dev-digest-121-ai-goes-offline) - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [Is Software Engineering Hard?](https://www.wearedevelopers.com/magazine/448-is-software-engineering-hard) - [4 reasons why you should learn Rust in 2021 – and maybe even have fun doing it](https://www.wearedevelopers.com/magazine/35-4-reasons-why-you-should-learn-rust-in-2021-and-maybe-even-have-fun-doing-it) - [Dev Digest 188: CfP time, the risks of NPM and IKEA algorithms](https://www.wearedevelopers.com/magazine/635-dev-digest-188-cfp-time-the-risks-of-npm-and-ikea-algorithms) - [Dev Digest 179: rm -rf, Agent Style, NPM hacks & Browser Design Tools](https://www.wearedevelopers.com/magazine/611-dev-digest-179-rm-rf-agent-style-npm-hacks-browser-design-tools)
