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 looking for a sharp, proactive Accountant to join our lean finance team at Atomic Machines. If you’re a detail-oriented professional who thrives on ownership, loves solving complex problems, and gets energized by the pace of a high-growth startup, this role is for you. Reporting to the senior accounting leader, this position provides learning potential in all facets of accounting and opportunities for well charted, merit-based, career growth.
At Atomic Machines, we are inventing the future of how things are made. As an Accountant, you will play a crucial role in shaping the financial foundation of a cutting-edge startup that is revolutionizing micromanufacturing and digital fabrication. You will be responsible for building and optimizing financial processes, with a strong focus on month-end close, financial statement review, internal controls, and year-end audit.
This is more than just an accounting role—it’s an opportunity to be part of a team that is bringing atomically precise manufacturing to life. You will collaborate with the facilities, operations, procurement, and strategic growth teams to align financial processes with our ambitious mission. This role is based in Santa Clara with a once-a-month visit to our Emeryville office.
What you’ll do:
- Own the month-end close calendar, driving it to completion on schedule by coordinating cutoff across the AP, payroll, and operations functions
- Prepare and post journal entries with full supporting documentation, ensuring accuracy and GAAP compliance
- Complete key balance sheet reconciliations, including bank, prepaid expenses, fixed assets, accrued liabilities, and deferred items
- Prepare the monthly financial statements package for Controller and Head of Finance review, including flux analysis and variance commentary
- Maintain a well-organised, audit-ready general ledger — clean account structure, consistent methodology, and complete support for every material balance
- Collaborate with Accounts Payable to ensure proper subledger cut-off and accurate accruals at period end
- Partner with Facilities, Operations, and Procurement to capture accruals for commitments that are not yet in the AP subledger
- Support tax and audit preparation by organising the financial data and supporting schedules required by external auditors and tax preparation parties
- Maintain internal controls over the close process — ensuring segregation of duties, approval documentation, and support retention are consistent with a pre-IPO control environment
What you’ll need:
- 3+ years of experience in accounting - preference will be given to associate and senior level personnel employed by CPA firms, ideally with exposure to manufacturing, hardware, or capital-intensive clients
- A first-principles mindset — you question assumptions, reframe problems from the ground up, and approach challenges with a foundational understanding rather than relying solely on precedent
- Familiarity with accounting tools like Bill.com, Ramp, Carta, and experience with any scaled ERP system with focus in the manufacturing environment
- Advanced Excel and Google Sheet skills
- Experience managing confidential information, exercising a high level of care of support data, and demonstrating exceptional attention to detail
- Strong knowledge of GAAP and accounting principles, with expertise in leases, debt, and equity transactions, with working knowledge of revenue recognition and inventory accounting
- Team player with the ability to deliver under pressure, meet deadlines, and adapt to a dynamic startup environment
- Bachelor’s degree in Accounting or Finance with significant career investments made in the field
Bonus Points For:
- A CPA license, or CPA track, is strongly preferred
- Experience in Big 4 accounting firms is a plus
- Experience with SQL or BI dashboard development is a plus
