The Principal Buyer will serve as a purchasing leader responsible for ensuring supply continuity, supplier execution, inventory health, and material availability for critical product families and capital equipment needs. This role requires a highly analytical, proactive buyer who can manage complex supplier relationships, identify and mitigate supply risk, influence cross-functional partners, and communicate clear recommendations to leadership in a highly regulated manufacturing environment.

The ideal candidate operates with strong ownership and urgency in a high-complexity manufacturing environment, anticipates supply risk before it impacts production or service commitments, uses data to drive supplier accountability, and balances service, inventory, cost, and compliance in daily purchasing decisions.

Key responsibilities include partnering with Production Planning, Manufacturing, Quality, Engineering, Finance, and Global Sourcing to align material availability with committed build plans, repair demand, OEM parts, tooling, services, and field service material requirements.
