Technical Product Manager Burlingame, CA

About the Job

Peak Energy is building the next generation of energy storage systems — purpose-built to deliver cheap, reliable power 're a rapidly scaling team tackling one of the defining infrastructure challenges of our time: enabling grids to run on clean, dispatchable energy. Our flagship product is a DC-coupled battery energy storage system (BESS) using sodium-ion cells, and we're bringing to market a hard-coupled solar-plus-storage system that eliminates DC-DC conversion losses through direct FET-based string switching.

We move fast, work on hard problems, and care deeply about getting the technical details right.

About the Job

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.

• 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

• 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 differentiation: system architecture, performance specifications, integration flexibility, and certification status
• Support product roadmap planning with well-reasoned recommendations grounded in technical and market analysis
• Work across teams to ensure product configuration options are well-documented, manufacturable, and commercially coherent
• Contribute to the development of Peak's long-term service agreement (LTSA) and service contract strategy — including what commitments we make on performance, availability, and maintenance, and how service offerings are structured and priced

• 2–5 years of experience in product management, technical program management, product development, consulting in a relevant field, or a closely related role
• Demonstrated experience in energy storage, grid-scale renewables, power electronics, or a related field — you need to be able to credibly engage with engineers on system-level technical questions
• Strong written communication skills — you can write a tight PRD, a clear competitive brief, or a well-structured strategy memo
• Comfort with ambiguity and the ability to drive decisions with incomplete information, while being honest about…
