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.

About the role

We are seeking a skilled engineer to design and develop integrated circuits, and to lead our custom-made chips for specific functions, development and maintenance of our PDK, circuit design, and device characterization projects. The ideal candidate will have a deep understanding of semiconductor processes, design methodologies, and tool flows. You will work closely with our process and fabrication teams to design test chips and models from scratch. 

Responsibilities

• Lead the development and validation of PDKs for new semiconductor process technologies.

• Collaborate with process and engineering teams to define PDK requirements

• Develop and optimize process-specific design rules, device models, and parasitic extraction files.

• Design test chips and experiments to drive modeling

• Create and maintain PDK documentation, including design manuals, application notes, and training materials.

Required Experience

• Minimum of 5 years of experience in PDK development or circuit design

• Proven track record of successfully leading test tape-out chips and analog circuit design

• Hands-on experience with device measurement, characterization, and modeling

• Proficiency with new or industry-standard EDA tools (e.g., OpenLane, Cadence, Mentor Graphics, Synopsys).

• Experience with scripting languages (e.g., Python, Tcl) for automation and tool integration.

• Strong communication and interpersonal skills, with the ability to work effectively in a collaborative team environment.

Nice-to-have

• Timing analysis 

• Open-source layout tools
