Own one or more critical commodity/category portfolios (examples: avionics/electronics assemblies, motors/actuators, battery packs, composite airframe structures, or machined flight-critical components) end-to-end: sourcing strategy, supplier selection, contract terms, qualification, ramp to volume, and long-term supplier development. Integrate with Engineering, Supplier Industrialization, Manufacturing Operations, Materials Planning, and Program Management to translate design and production requirements into supplier deliverables, readiness gates, and acceptance criteria; be the primary commercial and operational owner during design-to-production transitions.
