• Prepare and present executive-ready summaries of supply outlook, inventory trends, capacity constraints, material risks, scenarios, mitigation actions, and decisions required.
• Lead root-cause analysis for significant supply, schedule, inventory, and planning misses and drive sustainable improvements across processes, systems, data quality, and operating mechanisms.
• Establish planning governance, standard work, performance metrics, exception management, and master-planning best practices; coach planners and strengthen organizational planning capability.
• Operate in accordance with applicable quality, regulatory, compliance, and company requirements; proactively elevate risks that could affect customers or patients.

• Bachelor's degree or higher education preferred but not required.
• Experience leading integrated production or supply plans across multiple products, manufacturing lines, suppliers, sites, or distribution nodes in the medical device industry.
• Demonstrated experience leading cross-functional supply reviews, resolving complex constraints, and influencing senior-level decisions involving capacity, inventory, service, cost, and risk tradeoffs.
• Experience with advanced capacity modeling, supply scenarios, material requirements planning, inventory optimization, and executive-level decision support.
• Experience with ERP, MRP, advanced planning, business-intelligence, and data-analysis tools; advanced Microsoft Excel capability is required.
