• Commodity strategy: build and run the wire harness commodity strategy, covering supplier base, dual sourcing and cost roadmap.
• New part development: manage RFQs, technical and commercial evaluation, supplier nomination, and development through proto, PPAP and SOP, working with design, electrical engineering, quality and program teams.
• Should-cost and negotiation: prepare harness cost breakdowns (copper and cable cost by length and gauge, terminals, connectors, accessories, crimping, assembly and test labour, EOL testing, overheads, profit). Lead fact-based negotiations and annual price reviews.
• Copper and RM indexation: put copper-indexed pricing mechanisms in place and manage them, then validate supplier claims for raw-material price variation.
• Supplier development: assess and audit harness suppliers for capability, process control (crimp height and pull test, crimp cross-section, EOL/continuity testing, error-proofing), capacity and quality systems. Drive corrective actions and improvements.
• Connector and terminal sourcing: manage sourcing and lead times for branded connectors and terminals (TE, Amphenol, Molex, Aptiv, Yazaki, JST and others), including alternates and approved-equivalent strategies.
• VA/VE: find cost-reduction opportunities through routing optimisation, wire gauge and material changes, connector standardisation and design-for-manufacture.
• Supply continuity: track capacity, lead times and risks for long-lead and single-source components. Support ramp-ups and engineering change implementation.
• Commercial and documentation: manage POs, schedule agreements, purchase agreements, tooling (crimp applicators, assembly boards, test fixtures) and supplier performance scorecards.

What you’ll bring:

• Wire harness design and manufacturing: cutting, stripping, crimping, ultrasonic welding, soldering, sealing, taping, sleeving, conduits, overmoulding and formboard assembly
