Senior Buyer
San Francisco, CA
About the Company
Atoms is building the machines that power the next era of progress.
Over the last decade, software has transformed the digital world. But the physical world, where food is made, minerals are mined, goods are moved, and industries are run, remains far less intelligent, far less efficient, and far more constrained. We’re changing that.
Atoms builds Physical AI- real-world robots for the industries that move civilization forward, starting with food, mining, and transport. Our systems are designed to understand, predict, and control the real world with precision, turning complex physical operations into something more reliable, more scalable, and more productive.
We are roboticists, engineers, operators, and builders. We believe the next great technology companies will not only transform information, but the physical systems that shape everyday life.
If you want to work on hard problems with real-world impact, join us.
Responsibilities
- Support the supply chain team in building the operating system that enables Atoms to scale from early retrofit builds to thousands of human-driven AV data-collection vehicles, and eventually to large-scale driverless L4 fleet deployment.
- Process purchase orders end-to-end - from requisition through PO issuance, confirmation, and closeout.
- Manage vendor communication with suppliers of sensors, compute, LiDAR, and other AV hardware/electronics.
- Track orders proactively, monitoring lead times, flagging delays early, and escalating risks to delivery schedules.
- Coordinate invoicing with finance and suppliers, resolving discrepancies between POs, receipts, and invoices.
- Maintain accurate, audit-ready procurement records across systems.
- Build and refine PO workflows, templates, and tracking processes.
- Support supplier onboarding and help establish vendor management practices.
- Partner closely with engineering, hardware, and finance teams.
- Help select, configure, or improve procurement systems/tools as the team scales.
Requirements
- 2-5 years of hands-on experience as a Buyer or Senior Buyer, ideally in hardware, electronics, automotive, robotics, or another technical/AV-adjacent industry.
- Strong working knowledge of procurement systems (e.g., ERP/P2P platforms such as SAP, NetSuite, Coupa, Oracle, or similar).
- Proven skill in PO processing at volume and with accuracy.
- Excellent order tracking discipline.
- Sharp attention to detail, especially across POs, invoices, and shipment documentation.
- Clear, confident vendor communication skills, written and verbal.
- Comfort working in a startup environment with evolving processes and shifting priorities.
- A self-starter mindset - willing to build process, not just follow it.

Why Join Us
At Atoms, you’ll work on one of the defining challenges of our time-bringing automation into the physical world to drive real, lasting impact. We exist to uncover valuable unknown truths and turn them into progress, which means constantly pushing beyond what’s known and building what doesn’t yet exist. The work is ambitious and often challenging, but it’s grounded in a shared sense of purpose and a team committed to seeing it through together. Our work only matters if it serves others, and we know that meaningful progress depends on the trust of the people we serve and the strength of our team-so we invest in both, creating an environment where you can do your best work and grow.
What Else You Need to Know
This role is based in our San Francisco office. Atoms is a company driven by invention and continuous change - we are constantly reimagining our industries, building new products, and refining how we operate. We do our best work together. That’s why all of our office-based teams work onsite, five days a week.
