Principal Specialist, Master Scheduler; Onsite

Master Scheduler – Responsibilities

• 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 with 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 and expedite needs.
• 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 comply with ITAR, FAR/DFARS, AS9100, and internal quality procedures.
• Maintain audit‑ready schedule history and documentation to support DCMA, government, and customer audits.

• U.S. citizenship required for security clearance.
• Ability to obtain and maintain a U.S. government‑issued security clearance.
• University degree and minimum 5 years of relevant experience, or an advanced degree with minimum 3 years of experience.
• Prior experience in production scheduling and manufacturing environment.
• Experience with ERPs, MRP, MPS, and SIOP principles.
• Knowledge of configuration management and engineering change control.

• Bachelor’s degree in Supply Chain, Operations, Business, Engineering, or related field.
• Prior experience in production scheduling, supply planning, or operations in aerospace & defense.
• Excellent analytical, communication, and organizational skills.
• APICS/ASCM certification (CPIM, CSCP).
• Experience with program‑based manufacturing and contract deliverables.
• Proficiency in Power BI,…
