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 https://www.youtube.com/@SamZeloof and Jim Keller https://en.wikipedia.org/wiki/Jim_Keller_(engineer). 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 are looking for a Hardware Test Engineer to be the critical interface between every team at Atomic Semi. You will get to work across every we are building, applying a deeply scientific mindset to characterize tools, intuit potential problems, and diagnose complex failures.
This is a dedicated test and applications role. You'll know you've succeeded when you build and execute test plans that improve the design of our tools in your first month. By month 3, you will be autonomously solving highly complex problems for our positioning tools, and by month 6, your impact will scale across multiple teams and systems. Our philosophy is to get things built/tested in days or weeks, not months. Because of this, a portfolio is generally required to apply: show us the things you’ve built!
