Atoms is building Physical AI—real-world robots for industries including food, mining, and transport. This Senior Buyer role supports the supply chain team in scaling from early retrofit builds to large-scale autonomous vehicle fleet deployment.
You will own procurement end-to-end, ensuring every retrofit vehicle receives the right hardware (sensors, compute, LiDAR, electronics) on time with complete traceability from supplier PO through serial number, VIN, installer, calibration, and warranty history. This traceability model is central to the operating plan.
Key responsibilities:
- Process purchase orders end-to-end: requisition through issuance, confirmation, and closeout
- Manage vendor communication with suppliers of AV hardware and electronics, ensuring clear and timely correspondence
- Track orders proactively, monitor lead times, flag delays early, and escalate delivery risks
- Coordinate invoicing with finance and suppliers, resolving PO/receipt/invoice discrepancies
- Maintain accurate, audit-ready procurement records across systems
- Build and refine PO workflows, templates, and tracking processes as one of the team's first procurement hires
- Support supplier onboarding and establish vendor management practices for the AV supply base
- Partner with engineering, hardware, and finance teams to understand component needs and timelines
- Help select, configure, or improve procurement systems and tools as the team scales
This is a high-impact execution role at the center of Atoms' fleet scale-up. Every improvement in procurement speed, inventory accuracy, and supplier follow-up directly increases retrofit throughput, vehicle uptime, and data-collection capacity.
Atoms is based in San Francisco and operates on a five-day onsite model.
Requirements:
- 2–5 years of hands-on experience as a Buyer or Senior Buyer, ideally in hardware, electronics, automotive, robotics, or AV-adjacent industries
- Strong working knowledge of procurement systems (ERP/P2P platforms such as SAP, NetSuite, Coupa, Oracle, or similar)
- Proven skill in PO processing at volume with accuracy
- Excellent order tracking discipline and attention to detail 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
- Self-starter mindset; willing to build process, not just follow it
