 About the Job

You will own the project-level financial models that underpin investment decisions, financing negotiations, and partnership economics across Peak Energy’s portfolio. This is a hands-on role where your models will be used in real transactions—not shelved. You’ll work directly with the Chief Strategy Officer and CEO, and your work product will be seen by institutional investors, strategic partners, tax credit buyers, and lenders.

This is a high-impact role where your models directly shape strategy and capital allocation. You’ll work with an experienced team that has deep domain expertise in energy storage and project finance. This is a ground-floor opportunity at a company positioned at the intersection of two major trends: the energy storage buildout and the commercialization of sodium-ion battery technology.

Responsibilities

• Build and maintain project pro formas from early development through COD: revenue forecasts (capacity payments, energy arbitrage, ancillary services, resource adequacy), CapEx/OpEx assumptions, degradation and augmentation schedules, and terminal value.
• Model capital structures including tax equity (partnership flip, direct pay, transfer), preferred equity facilities, and project-level debt. Build waterfall distributions across complex multi-party structures.
• Support acquisition evaluation—take interconnection data, permitting status, offtake terms, and chemistry conversion assumptions and produce actionable go/no-go acquisition models on tight timelines.
• Analyze IRA incentive structures: ITC adders (energy community, domestic content), direct pay vs. transfer economics, and bonus credit qualification.
• Model CAISO market dynamics: tolling structures, merchant exposure, RA contract value, and curtailment scenarios relevant to sodium-ion’s positioning vs. lithium-ion.
• Prepare investor-facing outputs—clean, auditable models and summary materials for institutional capital partners, lenders, and insurance underwriters.
• Develop sensitivity and scenario analyses that articulate risk around a chemistry (sodium-ion) with a thinner bankable track record than lithium.

Minimum Qualifications:

• 5–7 years in renewable energy or storage project finance—at a developer, IPP, infrastructure fund, or advisory firm.
• Demonstrated experience building project finance models that have been through investor or lender diligence (not just internal screening).
• Strong command of ITC/PTC mechanics post-IRA, including tax equity structures.
• Advanced Excel modeling skills; comfort with Python or similar for scenario automation and data analysis is a strong plus.
• Familiarity with CAISO markets, interconnection processes, or California regulatory landscape preferred.
• Ability to communicate model assumptions and outputs clearly to non-financial stakeholders and external counterparties.

Preferred Qualifications:

• Experience with battery energy storage projects specifically (any chemistry).
• Exposure to project acquisition diligence or M&A in the energy space.
• Familiarity with tax credit insurance, transfer markets, or emerging IRA compliance guidance.

The salary range for this role is $140,000 - $200,000, with actual pay varying based on work location, experience, and skills. Our competitive benefits package includes flexible time off, comprehensive medical, dental, and vision coverage, a strong 401(k) plan, and equity opportunities.

Location: Burlingame, California

Position Type: Full-time, In-person

About the Company

Peak Energy is building the next generation of energy storage systems — purpose-built to deliver cheap, reliable power at scale. We'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.

Key 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 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

Required Qualifications

• 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 what you don't know
• Structured, analytical thinking — you approach product questions with rigor and don't make broad claims without backing them up

Desired Skills

• Hands-on experience with BESS procurement, project development, or system integration
• Familiarity with grid interconnection requirements, utility tariff structures, or wholesale energy market mechanics (ERCOT, CAISO, PJM)
• Exposure to relevant standards bodies or certification processes for electrical energy storage equipment
• Experience working with inverter manufacturers or EMS vendors on technical integration
• Background in a startup or high-growth hardware company

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

The salary range for this role is $150,000 - $200,000, with actual pay varying based on work location, experience, and skills. Our competitive benefits package includes flexible time off, comprehensive medical, dental, and vision coverage, a strong 401(k) plan, and equity opportunities.
