RF Power Engineering

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.

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 Role

We're hiring a RF Power Engineering for the fall term. The begins in September, with a commitment of 4 to 8 months. We're rebuilding the chip fabrication process from the ground up, so you'll be exposed to some really interesting and impactful work. You will rapidly develop and test the compact RF systems inside our fabrication tools. You'll be expected to identify problems, prototype solutions, productionize your prototypes, and deliver finished solutions that will revolutionize IC manufacturing.

Our philosophy is to get things built and tested in days or weeks, not months. Because of this, a portfolio is required to apply: show us the things you've actually built! If you've shipped a medium-to-high complexity system through a personal project or previous , you'd be a good fit here.
