Master Planner/Scheduler

About the role

Primus Aerospace has spent over 30 years delivering high-complexity precision machining, fabrication, and assembly for the aerospace and defense industry. We're ITAR-registered and AS9100D-certified, building to print for customers like Lockheed Martin, Northrop Grumman, Boeing, and General Dynamics. We are looking for a Master Planner/Scheduler to own production flow at our Lakewood facility — from open sales order to shipped part. You'll translate customer requirements and financial targets into a manufacturing schedule the floor can actually hit, and you'll be the one who catches problems early enough to fix them. This is a hands-on planning role in a high-complexity, tightly regulated production environment. You'll work closely with production, purchasing, and customers to keep work orders moving and delivery dates on track.

Responsibilities

• Scheduling & work order management
  • Review open sales orders and run ERP/MRP reports to sequence production orders for efficient manufacturing flow, minimizing changeovers and downtime
  • Generate and release manufacturing work orders, attaching the documentation production needs (prints, specs, customer requirements)
  • Build and maintain short-term production schedules across cells and lines, balancing customer demand, available supply, and operational efficiency
  • Adjust schedules as job type, volume, capacity, or conditions change — you'll rework the plan, not just flag that it slipped
• Materials & capacity
  • Determine purchasing needs for materials, including long-lead-time and overseas items, and plan shipments in advance to keep the schedule covered
  • Apply replenishment strategies (push/pull) to keep raw materials at optimal levels and maintain safety stock
  • Identify open capacity and flag it so we can negotiate additional customer volume and keep the floor active
  • Support expediting of supplier purchase orders when a schedule is at risk
• Cross-functional coordination
  • Participate in daily production stand-ups and floor walks to catch process issues early
  • Run or attend weekly scheduling meetings that keep procurement, the production floor, and customer service aligned
  • Work directly with production managers and operators to resolve scheduling conflicts
  • Partner with engineering, procurement, quality, and shipping to keep product moving through the full production cycle
• Customer & reporting
  • Communicate proactively with customers and internal teams on schedule status and delivery dates
  • Build recurring reports that give customers and leadership visibility into production flow and flag anything that could compromise an order
  • Support contingency planning for demand spikes so a surge doesn't derail the broader schedule

Requirements

• Bachelor's degree in Business Administration, Supply Chain Management, or a related field
• 3+ years of production planning and scheduling experience, ideally in a manufacturing environment
• Working knowledge of ERP systems and shop-floor manufacturing processes
• Solid Excel skills
• Strong organizational skills and comfort managing competing priorities in a fast-paced environment
• Clear, confident communication — you'll be talking to production, purchasing, and customers in the same day
• A detail-oriented mindset; small errors in a schedule cascade fast
• The ability to work independently while staying aligned with the broader team
• U.S. Citizenship required (to adhere to U.S. Government international trade regulations and ITAR/EAR export control access)
