Master Scheduler (MPS) Reports to: Planning Manager
Location: Newark
Department: Supply Chain / Production Planning
Job SummaryThe Master Scheduler owns and maintains the Master Production Schedule (MPS) for the site, translating customer demand into an executable build plan that is balanced against available capacity (labor, lines, equipment) and material supply. This role is the central point of coordination between Sales/Demand Planning and Production, ensuring the CM meets customer delivery commitments while maintaining efficient resource utilization.
Key Responsibilities- Master Schedule Ownership: Build, publish, and maintain the MPS across the planning horizon (typically rolling 4-13 weeks, with a longer-range rough-cut view), sequencing customer orders into production line schedules.
- Capacity Planning: Run Rough Cut Capacity Planning (RCCP) and/or detailed capacity checks against labor, machine, and line availability; identify bottlenecks and recommend load-leveling, overtime, or line-balancing actions.
- Demand Load Management: Reconcile customer forecasts/orders (demand signal) against the schedule; flag over/under-loaded periods and drive trade-off decisions with Sales/Program Management.
- Exception Management: Monitor schedule adherence, run daily/weekly exception reports (late materials, capacity conflicts, order changes), and drive resolution through cross-functional huddles.
- S&OP/SIOP Support: Provide MPS-level input into Sales & Operations Planning cycles; reconcile master schedule with the aggregate demand/supply plan.
- System Ownership: Maintain planning parameters (lead times, lot sizes, safety stock, calendars) in the ERP/APS system (e.g., SAP, Oracle, Kinaxis, NetSuite) to keep the MPS logic accurate.
- Customer/Program Interface: Communicate committed ship dates, capacity constraints, and schedule risks to planners/program managers as needed in a CM/EMS setting.
Required Qualifications- Bachelor's degree in Supply Chain, Operations, Business, Engineering, or equivalent experience.
- 3-7 years in production/master scheduling or demand planning, ideally in a Contract Manufacturing, EMS, or high-mix/low-volume manufacturing environment.
- Working knowledge of MRP/ERP systems and capacity planning tools (SAP, Oracle, Kinaxis RapidResponse, NetSuite, JDE, etc.).
- Strong understanding of MPS, MRP, RCCP/CRP, BOM structures, and demand-supply balancing.
- Advanced Excel; experience with planning/APS software a plus.
- APICS/ASCM certification (CPIM, CSCP) preferred.
Key Competencies- Cross-functional coordination (Sales, Materials, Production, Quality)
- Analytical/data-driven decision making under constraint (capacity vs. material vs. demand trade-offs)
- Clear communication of schedule risk to leadership and customers
- Comfort with ambiguity and fast-changing priorities typical of CM/contract environments
