Senior Buyer

Who We Are 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. What You'll Do 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. The core mission is to make sure every retrofit vehicle has the right hardware, in the right place, on time, with clean tracking from supplier PO → lot number → serial number → VIN → installer → calibration result → warranty/RMA history. This traceability model is central to the operating plan. Process purchase orders end-to-end — from requisition through PO issuance, confirmation, and closeoutManage vendor communication with suppliers of sensors, compute, LiDAR, and other AV hardware/electronics, ensuring clear, timely, and professional correspondenceTrack orders proactively, monitoring lead times, flagging delays early, and escalating risks to delivery schedulesCoordinate invoicing with finance and suppliers, resolving discrepancies between POs, receipts, and invoicesMaintain accurate, audit-ready procurement records across systemsBuild and refine PO workflows, templates, and tracking processes as one of the team's first procurement hiresSupport supplier onboarding and help establish vendor management practices for a fast-evolving AV supply basePartner closely with engineering, hardware, and finance teams to understand component needs and timelines specific to autonomous vehicle developmentHelp select, configure, or improve procurement systems/tools as the team scales Why this is exciting This is a high-impact execution role at the center of Atoms’ fleet scale-up. The Supply Chain team will help turn complex AV hardware into a repeatable, trackable, production-ready system. Every improvement in procurement speed, inventory accuracy, kitting discipline, and supplier follow-up directly increases retrofit throughput, vehicle uptime, and data-collection capacity. What We Are Looking For 2-5 years of hands-on experience as a Buyer or Senior Buyer, ideally in hardware, electronics, automotive, robotics, or another technical/AV-adjacent industryStrong 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 accuracyExcellent order tracking discipline — you don't let things fall through the cracksSharp attention to detail, especially across POs, invoices, and shipment documentationClear, confident vendor communication skills, written and verbalComfort working in a startup environment with evolving processes and shifting prioritiesA 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.
