Atomic SemiMillbrae, CAApril 12th, 2026
About Atomic SemiAtomic 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 TeamThe Process Team sits at the heart of our in-house device development, driving the design of each new generation of tools. This is unlike any role at a traditional foundry—we simultaneously develop recipes, apply novel materials, test and characterize our chips, and troubleshoot tools.About The RoleAs a Process Development Engineer at Atomic Semi, you’ll be responsible for experiment design and execution of new semiconductor and thin-film fabrication methods. We're looking for someone with both a strong understanding of traditional semiconductor processing methods and an open-mindedness to new techniques. It'll be helpful if you have the ability to digest and filter a large body of existing work (academic papers, books, etc.)This is a high-ownership role with lots of autonomy in a fast-moving startup environment. You’ll have the opportunity to contribute to novel R&D processes and influence tool design. Candidates should have hands-on cleanroom experience and a track record of developing nanofabrication recipes from scratch, ideally across multiple process steps.ResponsibilitiesWork in the lab to design and run experiments alongside senior process engineersRead academic papers and technical literature to inform experimental design; whiteboard ideas and iterate quicklyLearn and operate a range of semiconductor tools, including deposition, etch, lithography, and metrology systemsDevelop, transfer, and optimize process recipes across platforms with a focus on consistency, yield, and throughputAnalyze process data, troubleshoot recipe or equipment issues, and clearly document findings and results for the teamRequired ExperienceBS, MS or PhD in Electrical Engineering, Materials Science, Chemical Engineering or related fieldHands-on cleanroom experience with multi-step fabrication flowsExperience operating thin film deposition, dry etch, and lithography toolsRecipe development and optimization for some subset of thin film deposition, dry etch, or lithographyFamiliarity with key metrology such as ellipsometry, profilometry, SEM, etcNice-to-haveMechanical or maintenance experience with fab toolsFull device‐flow experienceWorking at Atomic SemiWe’re an early-stage hardware startup with solid funding, world-class advisors, and a lab/office in San Francisco, CA.Compensation: Atomic Semi is committed to fair and equitable compensation practices.
