Cssmerge The Senior Buyer supports the supply chain team by managing purchase orders and vendor communications for AV hardware components. They ensure traceability and timely delivery of hardware from suppliers to installation and calibration.
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.
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 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
