The Sr. Production Planner is responsible for developing and executing production plans that support manufacturing demand while optimizing inventory, capacity, and material flow across multiple products. This role requires a highly proactive and analytical individual who thrives in a fast-paced environment and can quickly adapt to changing priorities.

The ideal candidate is a hands-on problem solver and continuous improvement driver who does not accept the status quo. This individual will actively identify gaps, anticipate risks, and implement solutions that improve efficiency, product flow, and overall manufacturing performance.

Essential Duties And Responsibilities

To perform this job successfully, an individual must be able to perform essential duties and responsibilities satisfactorily. Reasonable accommodations may be made to enable individuals with disabilities to perform the essential functions.

• Develop and maintain production plans to meet manufacturing demand while optimizing inventory levels, capacity utilization, and manufacturing efficiency.
• Analyze production forecasts and consumption patterns to support effective demand planning and material requirements planning (MRP).
• Proactively identify potential production constraints, shortages, or delays and implement solutions to minimize impact to schedules.
• Coordinate production workflow across multiple product lines to ensure maximum performance and minimal delays.
• Lead planning activities related to VMI, KANBAN, and demand-driven replenishment programs.

• Collaborate with manufacturing, engineering, supply chain, and customer service teams to resolve production issues and improve product flow.
• Monitor execution of the production plan and quickly adjust schedules to respond to changing priorities or disruptions.
• Identify BOM discrepancies and drive rapid resolution to maintain accurate planning and inventory records.
• Lead projects to investigate and resolve inventory discrepancies, including those caused by BOM inaccuracies, system configuration issues, and transactional errors within NetSuite or other ERP systems.
• Reconcile inventory and ensure accurate allocation of materials against work in progress (WIP) and finished goods inventory (FGI).
• Develop and maintain reporting tools to track production performance, WIP status, and inventory levels.
• Investigate production problems, perform root cause analysis, and implement corrective actions.
• Partner with shop floor leadership daily to remove obstacles and improve manufacturing efficiency.
• Lead and support continuous improvement initiatives focused on cost reduction, process optimization, throughput improvement, and capacity planning.
• Act as a key planning resource for engineering changes and new product introductions.
• Demonstrate strong ownership and initiative by taking on additional projects and operational initiatives beyond day-to-day planning responsibilities to support evolving business needs, solve operational challenges, and drive continuous improvement.
• Lead cross-functional site or global projects focused on cost reduction, process improvements, inventory optimization, and operational efficiency.
