In this role, you will manage production scheduling and material flow within our Garden Grove manufacturing facility, taking responsibility for creating, optimizing, and maintaining master production schedules that maximize plant throughput and ensure on-time delivery to our customers.

As a senior-level contributor, you will bring strong analytical skills and crisis management agility to anticipate conflicts, balance resources, and keep operations running seamlessly.

Leadership & Core Responsibilities

Accountability

• Conduct rough-cut capacity planning (RCCP) and detailed line-level capacity analysis to balance labor, machinery, and material availability against sales forecasts and firm customer orders.
• Optimize Safety Stock, Reorder Points (ROP), and Economic Order Quantities (EOQ) to maintain lean inventory levels while minimizing stockouts and line downtime.
• Monitor Work-in-Progress (WIP) levels across the plant floor to prevent bottlenecks, control lead times, and optimize overall shop-floor flow.
• Maintain master data integrity (lead times, bills of materials (BOMs), routing times, batch sizes) within the ERP/MRP system to ensure accurate scheduling logic.
• Track, report, and drive improvement on core operational KPIs, including Schedule Attainment, On-Time In-Full (OTIF) delivery, Inventory Turnover, and Downtime due to material shortages.
• Ensure all supply chain processes and documentation comply with AS9100, ITAR, and applicable customer and regulatory requirements.
• Partner daily with Production Supervisors and Operations Managers to review schedule adherence, address line stoppages, and re-sequence orders dynamically when disruptions occur.
• Collaborate closely with Buyers and Procurement to ensure raw materials, components, and sub-assemblies arrive in-plant to align seamlessly with production start dates.

Empowerment

• Support Lean/Kaizen initiatives within the planning department, automating scheduling workflows, standardizing material replenishment strategies (e.g., Kanban/Pull systems), and reducing production lead times.
• Comply with all company policies and procedures.
• Perform other duties as assigned.
