Atomic Semi is seeking its first dedicated accounting leader, a Controller, to build and own the company's accounting function and financial foundations. This critical role involves end-to-end accounting operations, including managing the close process, establishing manufacturing and inventory accounting, implementing controls, driving audit readiness, and partnering with other departments. The Controller will also evaluate and scale accounting systems and tools, and eventually build and lead the accounting team.
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 team
This role sits on the Business Operations team, which is responsible for building the operational foundation that lets Atomic Semi scale. We believe our internal systems should be as thoughtful and ambitious as the products we build. As we grow, we need accounting infrastructure that's clean, scalable, and audit-ready.
About the role
As Atomic Semi’s first dedicated accounting leader, this Controller will own the accounting function and build the financial foundations we need for our next stage of growth. This is a critical role with real scope, and the processes, systems, and controls you put in place will define how this company operates for years to come.
You'll own all accounting operations from end-to-end. This includes running a clean, disciplined close process; building out manufacturing and inventory accounting; establishing controls and approval workflows; and driving audit readiness.
You'll partner closely with Finance, Operations, and the broader business to ensure our accounting infrastructure keeps pace with how the company is scaling and what comes next. This is an autonomous, high-ownership role in a fast-moving environment. The right person is comfortable with ambiguity, motivated to create structure where little exists, and confident running the function independently.
