About The Position

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. This work requires more than robotics. It requires deep integration across hardware, software, AI, operations, manufacturing, and real estate. We don’t just build machines in a lab. We deploy them into real environments, operate them, learn from them, and improve them until they work at scale. 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.

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 — you don't let things fall through the cracks
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

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, ensuring clear, timely, and professional correspondence
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 as one of the team's first procurement hires
Support supplier onboarding and help establish vendor management practices for a fast-evolving AV supply base
Partner closely with engineering, hardware, and finance teams to understand component needs and timelines specific to autonomous vehicle development
Help select, configure, or improve procurement systems/tools as the team scales
