People Operations Generalist

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.

We’re hiring a People Operations Generalist to run and build the day-to-day systems that support our people at Atomic Semi.

In this role, you’ll own and evolve the core of People Operations — payroll, benefits, immigration, onboarding, and the full employee lifecycle. You’ll make sure the fundamentals run smoothly, accurately, and on time, and you’ll also have the opportunity to improve how we do things as we grow. You’ll be the person employees come to with questions, guidance, and support, and a key partner in shaping a thoughtful, scalable People experience.

This role is perfect for someone who loves getting the details right, enjoys solving real problems, and is excited to build modern People Operations from the ground up at a company reinventing how semiconductors are made.
