As a Sr. Supply Chain Buyer & Planner, you will play a critical role in ensuring material availability from supplier selection through production readiness. You will be responsible for strategic procurement, supplier management, material planning, and clear-to-build (CtB) execution, partnering cross-functionally with Engineering, Production, Inventory, Quality, and Program Management to ensure production starts on time and customer commitments are met.

This role is ideal for someone who thrives in a fast-paced manufacturing environment, enjoys balancing both strategic sourcing and day-to-day execution, and takes ownership of solving supply chain challenges before they impact production.
