Full Stack Software Engineer - Fab

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

At Atomic Semi, we’re building a fast, small semiconductor fab from the ground up. The software team is responsible for everything that makes the fab run—writing the code that controls, manages, automates, and orchestrates the hardware that powers chipmaking.

About The Role

This role is for someone who loves to build. You’re motivated by turning ideas into working systems and know that getting something real is the first step toward making it great. At the same time, you care deeply about code quality and product taste. You’ll work directly with world-class engineers, designers, and researchers to create new interfaces and products from scratch. Experience with AI products is a plus, but what matters most is your excitement to push the boundaries of what’s possible with software, hardware, and cutting-edge infrastructure.

Responsibilities

• Develop and maintain our core web application that runs the fab
• Collaborate with process and automation engineers to make chips with robots
• Contribute to and integrate with firmware and embedded systems
• Build and extend backend services and infrastructure that keep the fab running

Required Experience

• Full stack development experience with fluency across modern web frameworks and cloud infrastructure
• Ability to build and ship both frontend and backend systems, including hardening prototypes into production-ready products
• Strong skills in rapid prototyping and iteration, with a balance of speed, quality, and craftsmanship
• Previous experience as founder or early engineer at a startup or in a zero-to-one role
• Published projects, open source contributions, or side projects that demonstrate technical creativity
• Experience building software that interfaces directly with hardware systems
• Working at Atomic Semi

Nice-To-Have

We’re an early-stage hardware startup with solid funding, world-class advisors, and a lab/office in San Francisco, CA.
