Summary: At Aptiv Interconnect, we inspire the world's most innovative teams by doing the right thing, the right way. We are seeking a Senior Production Planner to be the vital link between customer demand, plant floor operations, and procurement.

In this role, you will oversee end-to-end 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 100% on-time delivery to our customers. Operating in a high-mix, regulated aerospace and defense environment, you will address complex capacity bottlenecks, resolve material shortages before they impact production, and drive continuous improvement within our ERP/MRP systems and planning workflows. 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:

• Develop, maintain, and execute detailed finite daily and weekly production schedules for multiple production lines, work centers, and assembly areas.

• 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.

• Monitor Work-in-Progress (WIP) levels across the plant floor to prevent bottlenecks, control lead times, and optimize overall shop-floor flow.

• Act as an ERP/MRP super-user, maintaining master data integrity (lead times, bills of materials (BOMs), routing times, batch sizes) within the system to ensure accurate scheduling logic.

Cross-Functional Execution & Continuous Improvement

• 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.

• Optimize Safety Stock, Reorder Points (ROP), and Economic Order Quantities (EOQ) to maintain lean inventory levels while eliminating stockouts and line downtime.

• 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.

• Lead Lean/Kaizen initiatives within the planning department, automating scheduling workflows, standardizing material replenishment strategies (e.g., Kanban/Pull systems), and reducing production lead times.

• Ensure all supply chain processes and documentation comply with AS9100, ITAR, and applicable customer and regulatory requirements.

• Comply with all company policies and procedures.

• Perform other duties as assigned.
