Role Summary

The Supply Chain Planning Manager will oversee comprehensive supply chain operations for volume production, ensuring that materials, capacity, and inventory align perfectly with production schedules and ramp-up demands. Responsibilities include material requirements planning (MRP), contract manufacturer build plan oversight, inventory management, and supplier risk mitigation to sustain reliable production scaling.

Key Duties

• Convert production forecasts and build plans into precise MRP, procurement schedules, and supplier agreements.
• Continuously analyze and manage inventory, safety stock levels, and material utilization to balance waste reduction with uninterrupted production.
• Drive supply chain readiness and coordination across contract manufacturing partners for efficient production builds.
• Synchronize production schedules, material readiness, and logistics with contract manufacturers and suppliers supporting ongoing volumes.
• Implement support for engineering change controls during production-design revisions to maintain supply plan alignment.
• Oversee transitions from new product introduction (NPI) and pilot phases into full production ramps in close collaboration with related teams.
• Formulate and manage production build plans reflecting demand and business priorities at contract manufacturers.
• Track supplier lead times, capacity limits, and delivery commitments to handle production volume needs.
• Partner with procurement to ensure continuous material supply and manufacturing capacity as volumes grow.
• Spot potential material shortages, supply interruptions, or single-source risks that may threaten production continuity.
• Maintain transparency of key component paths and long-lead items supply across the production supply base.
• Monitor critical supply chain KPIs such as forecast accuracy, inventory turnover, and on-time delivery for production materials.
• Communicate regular updates on production supply status and risks to cross-functional leadership.

Qualifications

• Bachelor's degree in Engineering, Materials Science, Supply Chain Management, or a related discipline.
• Minimum of 5 years of experience in supply chain planning, material planning, or MRP execution, preferably within electronics, semiconductors, or hardware manufacturing sectors.
• Demonstrated success in managing material and supply plans across multiple sites and regions while collaborating with suppliers and contract manufacturers to meet production schedules.
• Practical knowledge of ERP or MRP software such as SAP, Oracle, or NetSuite, coupled with strong Excel and data analysis capabilities.
• Exceptional analytical skills, forecasting ability, and adeptness in managing cross-functional stakeholder relationships.
• Experience with inventory optimization strategies is a valuable advantage.
