Peak Energy Role: Senior Director of Manufacturing   Location    Burlingame, CA (with significant time at Sacramento, CA manufacturing facility)   Department    Manufacturing   Reports To    VP of Manufacturing Position Type    Full-time   About Peak Energy   Peak Energy Technologies is the first American venture to advance globally proven Sodium-Ion battery systems as the storage standard for the new era of renewable energy on a resilient grid. Sodium-Ion is cheap, readily available and safe, making it the leading contender in a rapidly evolving market.   We're a team of about 105 today growing rapidly as we move from pilot through commercial scale-up. We operate with modern tooling, including a company-wide AI platform and a builder-first culture that rewards taking ownership end-to-end.   Our leadership team is powered by decades of expertise in scaling gigawatt-level innovation at world-class companies such as Tesla, Northvolt, Apple, Powin, Enovix, Zipline, Solid Power, and Fluence. We are backed by strategic investment and product partners such as Xora, Eclipse Ventures, and TDK Ventures.   We are a team of engineers, operators, entrepreneurs, and partners driven by a shared ambition to set the new performance standard for renewable energy and grid resilience.     About the Role - 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.     What You'll Do   (Responsibilities) Lead the manufacturing engineering and process development organization through the ramp from pilot to giga-scale production   Define and execute the production ramp plan, including equipment specification, line layout, yield curves, and cost-down roadmap across our Burlingame and Sacramento sites   Build and develop a world-class manufacturing leadership bench spanning process engineering, equipment, quality, automation, and facilities   Partner with engineering to drive design-for-manufacturing into the product roadmap from day one, not as a downstream cleanup exercise   Own manufacturing KPIs end-to-end: throughput, yield, OEE, cost per kWh, and safety performance   Drive process maturity from pilot-scale engineering handoffs into stable, repeatable, audit-ready production for commercial customer shipments
