Supply Chain Buyer / Planner

Amca•El Segundo, CA

About The Position

Amca is building America’s new industrial base. Since the 1990s, our ability to build new aviation and military systems and maintain the ones we already have has eroded. Today, the gap between what the nation needs to produce and what it is capable of producing is the largest it has been in generations. To help close that gap, Amca rapidly develops and manufactures new critical components and subsystems required to build and sustain the planes, military vehicles, and core infrastructure America needs. Today, we operate seven factories nationwide, including our advanced prototyping and testing headquarters in El Segundo, and deliver avionics, hydraulic, and electrical components for platforms such as the F-35, F-16, F/A-18, 737MAX, 787, A320neo, A321, Mk-48, and M1 Abrams. Overview: The Buyer / Planner owns procurement and build planning for Amca's manufacturing operations. You will be responsible for sourcing and purchasing the parts and materials that go into our builds, tracking hardware from PO through completion, and ensuring the manufacturing floor is planned and stocked to support active builds. You'll also play an active role in building and vetting our supplier base — including occasional supplier visits.
