Reporting to the Director, S&OP / Planning and leading a team of site‑based Production & Supply Planners, this role ensures raw materials, components, and capacity are aligned to produce a reliable, achievable production plan at every facility. The MRP Manager will also play a lead role in defining and organizing the company’s transition to a new ERP/MRP platform, ensuring planning processes, data, and reporting are standardized and ready to scale across sites.

• Lead cross-site MRP and production planning, directly managing the Production & Supply Planners at each manufacturing site (East, West, and NYC) to ensure a consistent, coordinated planning approach.
• Own the accuracy and integrity of the Master Production Schedule at each site, ensuring alignment with the consolidated demand plan, raw‑material and component availability, and equipment capacity.
• Partner with the Director, S&OP / Planning in the monthly Sales & Operations Planning process, reconciling the network‑wide demand plan with production capacity and supply constraints.
• Standardize MRP planning parameters and best practices across all sites, including safety stock levels, reorder points, lot sizing, and lead times.

• Own user acceptance testing and training for site planners during the ERP/MRP transition, and drive adoption and change management through go‑live and stabilization.
• Coach, develop, and manage the performance of the Production & Supply Planner team across sites, setting clear expectations and providing regular feedback.
• Monitor and report planning KPIs across the network (schedule adherence, on‑time delivery, inventory turns, and plan‑to‑actual variance), leading root‑cause analysis and corrective action.
• Partner with purchasing to resolve material shortages and align supply commitments with the production plan, with particular attention to long‑lead‑time and shelf‑life‑sensitive raw materials and components.
• Identify and help resolve capacity constraints across sites, prioritizing production and coordinating trade‑offs with site leadership and the Director, S&OP / Planning.
• Serve as the subject‑matter expert on MRP/ERP planning logic and system configuration; troubleshoot data integrity issues and drive continuous improvement in planning accuracy.
