Job Description

General Opportunity 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. Don’t see the right role for you?

Here’s a non-exhaustive list of what we’re working on: - Mechanical systems (high precision mechanical design, control systems, fluids, temperature & vibration control, optics) - Electrical systems (RF, high voltage, FPGAs) - Software (firmware, low-latency controls, data analysis, robotics and automation) - Nanofabrication (process engineering, chemistry, device physics, transistor modeling) We’re moving really fast and our needs are changing fast. If you think you can help us build something great, let’s chat!
