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
