Senior Production Material Planner, Energy Storage

About Redwood Materials Redwood Materials was founded in 2017 by JB Straubel, co-founder and former CTO of Tesla, on a simple but radical idea: the critical minerals powering the energy transition already exist. They just need to come back. Today Redwood is the largest lithium-ion battery recycler in North America — recovering, refining, and redeploying critical minerals from end-of-life batteries back into the supply chain. On the energy side, Redwood has deployed the largest second-life battery project in the world, delivering power to AI data centers in months rather than years using proprietary energy architecture engineered entirely in-house. The company is profitable, the market it operates in is projected to grow 20 to 50 times over the next decade, and Redwood is the only company with the supply chain, the technology, and the operational scale to lead it. Position Summary: The Senior Production Material Planner is a career-level role that owns material planning for assigned electronics and mechanical commodities supporting battery energy storage system (BESS) production. The role converts production schedules into supply requirements through MRP, manages planning parameters and master data, and drives suppliers to deliver against the build plan. Working with Supply Chain, Engineering, Manufacturing, and Finance, the role identifies material constraints early, resolves shortages, and manages the inventory impact of engineering changes and new product introduction builds. Essential Duties and Responsibilities • Lead material planning for assigned electronics and mechanical commodities, translating production schedules and demand into MRP-driven supply requirements • Maintain planning parameters and master data (lead times, lot sizes, safety stock, bills of material) to reflect supplier capability and meet inventory, service level, and cost targets • Perform daily supply and constraint management, including clear-to-build and run-out analysis, and resolve shortages and exceptions ahead of the build schedule • Serve as the primary interface with assigned suppliers on delivery status, schedule changes, and issue resolution, escalating to Global Supply Chain Management, Quality, or Engineering when required • Manage engineering changes and product transitions to minimize excess and obsolete inventory and maintain continuity of supply • Support new product introduction builds by confirming material readiness from prototype through production ramp • Develop, track, and report material KPIs (clear-to-build, days on hand, excess and obsolete inventory, supplier on-time delivery) to Supply Chain, Manufacturing, and Finance Skills, Knowledge, and Abilities • Bachelor's degree in Supply Chain, Business, Engineering, or a related field, or equivalent experience • 5+ years of material planning, production planning, or supply chain experience (3+ years with a Master's degree), ideally in high-volume electronics, automotive, or battery manufacturing • Working knowledge of MRP/ERP systems, bills of material, and discrete manufacturing planning processes • Working knowledge of electronics and mechanical components such as PCBAs, harnesses, busbars, and machined parts • Proficiency in Excel and data analysis for clear-to-build, run-out, and inventory analysis • Ability to manage supplier relationships and secure delivery commitments from domestic and international suppliers The position is full-time.
