Master Scheduler (Onsite

Master Scheduler

The Master Scheduler is responsible for developing, managing, and maintaining the Master Production Schedule (MPS) for a site, value stream, or key program within an Aerospace and Defense (A&D) environment. This role ensures the alignment of customer demand, internal capacity, material availability, and inventory targets across long- and short-term planning horizons. Operating at the intersection of planning, execution, and program management, the Master Scheduler plays a critical role in achieving on-time delivery, revenue goals, and customer satisfaction—while maintaining compliance with strict regulatory and contractual standards.

What You Will Do:

• Create and maintain an 18-month rolling Master Production Schedule based on demand forecasts, firm orders, and internal requirements
• Translate customer demand into executable production plans, balancing constraints such as capacity, labor, and materials
• Incorporate make-to-stock, make-to-order, assemble-to-order, and engineer-to-order strategies into schedule logic
• Establish and manage the MPS supply load across all value streams and programs
• Own the supply plan and ensure alignment with the demand plan and financial targets
• Support the Sales, Inventory, and Operations Planning (SIOP/S&OP) process by providing accurate, timely, and feasible schedules
• Perform long-term capacity-to-build (CTB) analysis and scenario planning for pull-ins, customer commits, and late changes
• Partner with Demand Planners to reconcile commit/request gaps and recommend changes to output plans
• Define and manage product fulfillment strategies, inventory targets, and stocking policies for finished goods
• Conduct target stock analysis and drive finished goods availability in line with program and business objectives
• Support both revenue and non-revenue requirements (e.g., spares, rework, test inventory)
• Monitor and respond to schedule exceptions such as material shortages, engineering changes, ECOs, and quality holds
• Own short lead time simulations, supply recovery planning, and updates to the schedule based on real-time constraints
• Maintain the Recommended Changes File for output plan modifications, and communicate changes in quantity and dollar impact
• Support monthly and quarterly capacity reviews, ensuring assumptions are validated and actionable
• Balance the rate plan across value streams or factory lines to optimize throughput and minimize bottlenecks
• Evaluate the feasibility of new product ramps or high-mix schedules based on capacity, supplier readiness, and resource constraints
• Coordinate with Engineering and Configuration Management to integrate ECOs, ECPs, and NPI builds into the master schedule
• Schedule First Article Inspections (FAIs) and support ramp-up/ramp-down transitions
• Align NPI timelines with customer validation requirements and production readiness
• Track and report key KPIs including Schedule Adherence, Schedule Attainment, On-Time Delivery (OTD), and inventory accuracy
• Provide visibility into schedule variances, risks, and recovery actions
• Support leadership reporting on output plans (quantity/dollars) and deviations from the business plan, production plan, and shipment targets
• Partner with Supply Chain and Procurement to ensure material availability aligns with the schedule
• Provide early visibility of supply needs for long-lead or high-risk components
• Proactively address shortages, expedite needs, and support hot parts resolution
• Act as a key liaison between Operations, Program Management, Engineering, Finance, and Contracts teams
• Provide accurate Estimated Completion Dates (ECDs) and maintain communication with stakeholders regarding schedule changes or risks
• Participate in customer reviews, program meetings, and Integrated Product Teams (IPTs)
• Ensure all scheduling activities are compliant with ITAR, FAR/DFARS, AS9100, and internal quality procedures
• Maintain audit-ready schedule history and documentation to support DCMA, government, and customer audits
