Your Responsibilities

- Manage call-offs, releases, and replenishment signals to suppliers and contract manufacturers within agreed planning horizons
- Validate system outputs and correct exceptions caused by master data issues, forecast anomalies, or BOM/route changes
Supplier & Contract Manufacturer Coordination (External Execution)
- Align with contract manufacturers or suppliers on build schedules, material readiness, inbound windows, and inventory positions (supplier/CM-managed)
- Coordinate with suppliers to confirm capacity, lead times, allocation constraints, and delivery commitments
- Drive adherence to orders / plans and escalate deviations through defined escalation paths
- Support sourcing strategies by providing data on supply reliability, constraints, etc.
- 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

- 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).
Preferred
- APICS/ASCM certification (CPIM, CSCP) or equivalent.
- Experience with Power BI (or similar), advanced Excel, and data visualization/reporting.

constraints.
This role requires strong cross-functional collaboration internally (Demand Planning, Supply Planning, Inventory Planning, S&OP and S&OE leads, Operational Buying, Quality, Logistics) and disciplined supplier-facing coordination externally (CMs, tier suppliers, freight providers). You will balance service, inventory, cost, and risk, and lead exception management when supply and demand do not match.
