About Atomic Semi
Atomic Semi is building a small, fast semiconductor fab.
It’s already possible to build this with today’s technology and a few simplifications. We’ll build the tools ourselves so we can quickly iterate and improve.
We’re building a small team of exceptional, hands-on engineers to make this happen. Mechanical, electrical, hardware, computer, and process. We’ll own the stack from atoms to architecture. Our team is optimistic about the future and we want to continue pushing the limits of technology.
Smaller is better. Faster is better. Building it ourselves is better.
We believe our team and lab can build anything. We’ve set up 3D printers, a wide array of microscopes, e-beam writers, general fabrication equipment - and whatever is missing, we’ll just invent along the way.
Atomic was founded by Sam Zeloof and Jim Keller. Sam is best known for making chips in his garage, and Jim has been a leader in the semiconductor industry for the past 40 years.
About the team
The Tool Software team builds the software that runs Atomic Semi’s semiconductor fabrication tools. We work across the stack, from microcontroller firmware and real-time control to Linux applications for calibration, diagnostics, simulation, build/release infrastructure, and over-the-air deployment.
Our software sits close to the hardware and directly affects tool performance, uptime, process repeatability, and fab throughput. We partner closely with electrical, mechanical, process, and fab teams to bring new equipment online and scale it into production.
About the role
You will build production Rust software for semiconductor fabrication equipment: the systems that help turn precise software instructions into real physical processes.
Your work will integrate with microcontroller-based systems to sequence and control fabrication processes. You will also build the software capabilities behind a modern, software-defined fab, including calibration, diagnostics, telemetry, and tool operation.
This is a hands-on systems role for someone who wants their Rust code running close to the hardware, controlling complex equipment, and directly shaping how chips get made.
