Controller, Accounting, Accounting Manager

Atomic Machines is ushering in a new era of micromanufacturing with its Matter Compiler™ technology platform. This platform enables new classes of micromachines to be designed and built by providing manufacturing processes and a materials library that are inaccessible to semiconductor manufacturing methods. It unlocks MEMS manufacturing not only for device classes that could never be produced by semiconductor methods, but also for entirely new categories.

Furthermore, this digital platform is fully programmable in the way 3D printing is digital—but whereas 3D printing produces parts of a single material using a single process, the Matter Compiler™ technology platform is a multi-process, multi-material system: bits and raw materials go in, and complete, functional micromachines come out. The Atomic Machines team has also created an exciting first device—made possible only through the Matter Compiler™ technology platform—that we will be unveiling to the world soon.

Our offices are in Emeryville and Santa Clara, California.

We’re hiring a Controller to build the financial backbone that will carry us from breakthrough prototypes to high-volume production. This is a hands‑on role for a builder who can establish strong fundamentals quickly—close, controls, inventory/cost accounting, systems, and audit readiness—and then hire and lead a team to support the next stage of growth. Reporting to the CEO, you’ll be the company’s accounting leader and a key partner to operations.

You’ll ensure the integrity of our financials, build scalable processes and policies, and serve as the primary stakeholder for financial systems (ERP and related infrastructure). You will work closely with Finance, Operations, and Strategic Growth to align accounting infrastructure with the company’s mission and pace. This is an autonomous, fast‑paced environment, and you will contribute to a world‑changing vision.

This role can be based in Emeryville or Santa Clara
