Senior Director of Manufacturing

Senior Director of Manufacturing The Senior Director of Manufacturing owns the end-to-end manufacturing strategy and execution for Peak's sodium-ion battery systems as we move from pilot through giga-scale commercial production. You will lead manufacturing engineering, manufacturing operations, process development, facilities, equipment, yield, and ramp readiness across the full BESS stack, spanning our Burlingame pilot operation and our Sacramento manufacturing facility. This role exists right now because Peak is in the most consequential operational moment of the company. First commercial customer deliveries are imminent, multi-year supply contracts are landing, and the production system we build over the next eighteen months will define our cost structure, our ramp velocity, and our ability to meet the grid-scale demand coming through 2027 and beyond. You'll partner closely with engineering, supply chain, and our commercial team to bring product to market and stand up the production system that supports it. You'll inherit a strong technical bench and an ambitious roadmap, and you'll have the autonomy to build the manufacturing organization the company needs. This role is for a builder. Someone who can move from in the weeds problem solving to board-level planning in the same day, and who wants to own outcomes and manage the process.
