Master Scheduler

Job Title: Production Planner / Master Scheduler Job Description This role leads the integrated production planning function and owns the master production schedule for a large, complex manufacturing operation. You will establish and run the Sales, Inventory & Operations Planning (SIOP) process, build robust planning and ERP data discipline, and translate high-level demand into executable work-center and station-level plans. Operating in a restart and scale-up environment, you will balance capacity, inventory, lead times, and operational constraints to support reliable customer deliveries while driving continuous improvement in planning effectiveness. Responsibilities Own and manage the master production schedule, aligning customer backlog, demand forecasts, capacity, material availability, operational constraints, and delivery commitments. Establish and lead the SIOP process, including defining demand and capacity assumptions, developing scenario recommendations, documenting decisions, and ensuring action follow-through. Obtain leadership approval for major commercial, spending, and capacity trade-offs and ensure alignment to a single integrated plan. Partner cross-functionally with Sales, Engineering, Supply Chain, Materials, Production, Quality, Finance, and other stakeholders to maintain a unified, integrated production plan. Develop production ramp scenarios that define customer build-slot allocation, model and propulsion mix, labor requirements, station capacity and buffers, alternative production rates, and delivery impacts. Establish schedule approval and change-control rules, including a protected near-term schedule, and manage changes within delegated authority. Escalate schedule conflicts that affect customer commitments, spending, or capacity with clear recommended options to Operations leadership. Ensure all scheduling activities support compliance with safety, quality, and regulatory requirements. Own the Clear-to-Build process to ensure schedules released to the production floor are fully supported by customer configuration approvals, engineering releases, BOMs and drawings, engineering change incorporation, material availability, tooling, labor and station capacity, and applicable quality requirements. Implement and enforce readiness signoffs from responsible functions, including Procurement confirmation of critical material commitments, prior to schedule release. Hold schedule releases when required conditions are not met and escalate proposed exceptions with documented risks, owners, and recovery actions for leadership decision. Translate the master schedule into detailed work-center and station-level execution plans that support smooth production flow and clear floor-level accountability. Engage regularly on the production floor with Manufacturing leadership to validate actual progress, identify constraints, and adjust plans as needed. Verify planning-critical BOM and lead-time inputs with Engineering and Procurement, assign discrepancies to responsible data owners, and drive timely resolution to prevent shortages and delays. Establish ERP planning data standards and validation routines for BOMs, routings, lead times, calendars, and planning parameters in collaboration with responsible functions. Maintain planning-owned ERP parameters while coordinating closely with Engineering for technical BOM ownership and Procurement for supplier commitments. Serve as the planning lead for Epicor implementation, stabilization, and ongoing improvement, ensuring that planning logic accurately reflects operational reality. Use advanced Excel and ERP reporting tools to support scenario planning, capacity analysis, and data-driven decision-making. Act as the escalation point for complex scheduling and production planning issues across programs and product platforms. Use reliable reporting, capacity modeling, and scenario analysis to identify bottlenecks, constraints, schedule risks, and recovery opportunities, and refine assu…
