Strong understanding of BOM‑driven planning, item master data, lead times, supplier order policies, purchase order discipline, and material readiness reporting. Experience working in high‑mix / low‑volume or complex hardware environments where engineering changes, long‑lead materials, and configuration control affect procurement execution. Ability to work across Engineering, Program Management, Supply Chain, Quality, Configuration Management, Finance, suppliers, and contract manufacturers to resolve material and schedule issues. Working knowledge of supplier communication, expediting, PO management, shortage management, receipts, and planning metrics such as clear‑to‑build, past‑due PO status, and supplier on‑time delivery.

Strong organizational, analytical, and communication skills with the ability to provide clear status, elevate risks, and drive follow‑through in a fast‑moving environment. Advantages Direct experience supporting space hardware, satellite electronics, defense electronics, or other mission‑critical high‑reliability programs. Experience transitioning planning or procurement processes from spreadsheets to a more mature MRP/ERP/PLM environment. Experience planning material into outsourced manufacturers, Contract Electronics Manufacturers (CEMs), EMS providers, PCB suppliers, or box‑build partners. Experience procuring or planning EEE parts, printed circuit assemblies, electronic components, long‑lead materials, or other space‑grade hardware.
