[Hiring] Material Planning Manager @Prime Matter Labs

Role Description

The MPM Manager owns cross-site material requirements and production planning across Prime Matter Labs’ manufacturing network. 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 MPM will also play a lead role in defining and organizing the company’s transition to a new ERP/MPM platform, ensuring planning processes, data, and reporting are standardized and ready to scale across sites.

Responsibilities

• Lead cross-site MPM 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 MPM planning parameters and best practices across all sites, including safety stock levels, reorder points, lot sizing, and lead times.
• Help define and organize the company’s ERP/MPM system transition: document current-state planning processes, define future-state requirements, and translate them into system configuration in partnership with IT and finance stakeholders.
• Lead data readiness for the ERP/MPM transition, including item master, bill of materials, routing, and lead-time data across all sites, and coordinate data migration, testing, and validation.
• Own user acceptance testing and training for site planners during the ERP/MPM 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 MPM/ERP planning logic and system configuration; troubleshoot data integrity issues and drive continuous improvement in planning accuracy.
• Support analysis of how the long-term forecast impacts equipment capacity across the network, informing new-project site assignments and future equipment needs.
• Ensure each site maintains a firm four-week production schedule, providing planners with the data and direction needed to hold the plan.
