Lead accounting operations for a manufacturing startup: establish controls, month/quarter/year close, inventory/WIP/COGS costing, select and implement ERP, ensure audit and tax readiness, and hire and grow the accounting team.
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.
About The Role:We’re hiring a Controller to build the financial backbone that will carry us from breakthrough prototypes to high-volume production.

- Build manufacturing accounting foundations: implement and maintain inventory accounting, WIP/COGS mechanics, costing methodology (standard/actual as appropriate), reserves (scrap/obsolescence), and physical inventory processes.
- Partner with Operations on cost visibility and process scale: analyze manufacturing costs, improve transparency, and drive decision-ready reporting on unit economics and efficiency.
- Select and implement scalable systems: lead evaluation and rollout of ERP/accounting infrastructure and supporting tools (AP automation, expense management, close management).
- Design and maintain internal controls and accounting policies: ensure compliance with GAAP and support future financing, audits, and growth needs.
- Own external audit readiness: serve as primary point of contact for auditors, maintain support documentation, and drive a smooth annual audit process.
- Coordinate tax compliance: partner with external advisors to ensure accurate and timely federal/state filings and support tax planning needs.
- Build and lead the accounting team: hire, develop, and manage a team as the business scales; establish a high-accountability, high-ownership culture.
What You’ll Need:
- CPA and 10+ years of progressive accounting experience, ideally in manufacturing, hardware, or capital equipment businesses; 5+ years in a Controller or senior accounting leadership role.
- Experience implementing or scaling ERP systems (NetSuite, SAP, Oracle, etc.

- Systems implementation experience, including ERP selection/implementation and building accounting infrastructure that scales.
- Strong analytical and problem-solving skills; high attention to detail with the ability to operate at startup speed.
