Peak Energy Job Title:  Technical Product Manager Group: Product Team Reports To:  Head of Product Location:  Burlingame, California Position Type: Full-time, Onsite/Hybrid   About Peak Energy Peak Energy 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.     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 TDK Ventures and Eclipse 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 - Technical Product Manager We're looking for a Technical Product Manager to join the product team and own the intersection of product requirements, hardware specifications, and go-to-market configuration strategy. This is a role for someone who is genuinely comfortable going deep on technical content — reading through standards documents, interrogating engineering tradeoffs, and translating them into clear, actionable product requirements — while also thinking at the level of market positioning and product offering strategy.   You'll work closely with our engineering, commercial, and operations teams to define what we build and how we package it. You won't be managing external customer relationships day-to-day, but your decisions will directly shape what customers experience: what configurations are available, what certifications we hold, our strategy around power conversion and software, and how our product competes on technical merit in the markets we serve.     What We Offer A high-ownership role with direct influence over Peak's product strategy at a pivotal stage of company growth Competitive salary and meaningful equity — we want you to share in what we're building The opportunity to work on a genuinely hard technical problem with real infrastructure stakes A small, high-caliber team that values directness, technical depth, and getting things right     What You'll Do (Responsibilities) Product Requirements Definition Own and maintain detailed product requirements documents (PRDs) covering hardware specifications, electrical and mechanical configurations, construction and installation requirements, and operational capabilities Define requirements across energy and power dimensions — including power constraints, round-trip efficiency, auxiliary load budgets, and thermal operating envelopes Translate market, regulatory, and customer input into clear engineering requirements and acceptance criteria Track and maintain Peak's certification and compliance roadmap across relevant standards (e.g., UL 9540, IEC 62933, IEEE 693, NEC Article 706) Work with engineering to evaluate tradeoffs in hardware design decisions and ensure requirements reflect real-world deployment constraints   Product Offering Strategy Define and maintain Peak's inverter compatibility matrix — identifying target integration partners, characterizing interface requirements (communication protocols, control modes, grid-forming capability), and driving qualification processes Help shape Peak's EMS offering strategy — defining integration requirements, characterizing how EMS capabilities should be packaged and positioned, and ensuring our product works seamlessly within customers' control environments Contribute to competitive analysis of BESS products, focusing on technical differe
