Proactively identify material risks (e.g.

shortages, long lead-time exposures, logistics disruption) Lead cross-functional recovery actions (substitution, expedite, reschedule, partial shipments) Run scenario checks («what-if») to quantify impact on service levels, production, and inventory Maintain a risk dashboard for critical materials and define mitigation plans Cross-Functional Collaboration & Planning Governance Participate in regular planning cadences (e.g., Supply review, shortage meetings, S&OE coordination) Provide clear, timely communication to stakeholders on constraints, risks, and mitigation options Data Quality, Compliance & Continuous Improvement Maintain high-quality master data (e.g.

material master, lead times, vendor data, MRP types, safety stock, BOM accuracy) in collaboration with Master Data/Engineering Report (Excel/Power BI) and track KPIs and highlight root causes of recurring issues Contribute to sustainability objectives by reducing waste, avoiding unnecessary premium freight, and optimizing material usage Your Qualifications Bachelor's degree in Supply Chain, Logistics, Business, Engineering, or related field 5 years experience in material planning, supply planning, procurement coordination, or inventory management-ideally within outsourced/ external manufacturing environment Strong working knowledge of ERP / MRP (SAP, Oracle, or similar) and planning fundamentals Demonstrated experience managing suppliers/CMs in a global environment (multi-time-zone, multi-location) Strong analytical and problem-solving capabilities with a structured, data-driven approach.

Familiarity with planning and supply chain concepts: lead times, MOQs, safety stock, forecast consumption, service/inventory trade-offs Exposure to NPI/change control processes and lifecycle planning (phase-in/phase-out).
