Founding Product Manager
⚡️About Volter
AI and renewables are the 21st Century's two largest megatrends and they're colliding in the world's largest industry: energy. AI has made intelligence abundant, so human brains are no longer the bottle neck, cheap and secure power is.
The people, businesses and countries that have access to cheap, clean and secure power will lead this century. Renewables can deliver it, but they’ve turned a previously static predictable commodity into a huge complex changing forecasting and optimisation problem that the industry’s decades-old systems were never built to solve.
Volter exists to solve it. We’re building the first AI native operating system for business energy, so that every business can run on power that’s cheaper, cleaner and more secure. Octopus and Kraken did this for homes; we’re doing it for business.
And it’s working. We launched our platform in early 2026 and have already 20x revenue with customers from all across the UK now using the Volter platform. We’re still a small team, so you’ll shape the product, the tech and the culture from the ground up.
🔋 Where you plug in
We’re hiring a Product Manager to own how Volter builds product: the platform our customers and partners use, and the internal tools that run our pricing, ops and commercial teams. Both matter equally, because the internal platform is how we scale whilst staying lean. A year in, success looks like a roadmap the whole company understands, products brokers and customers rely on, and internal tools that have saved our teams thousands of hours.
⚙️ What you’ll power
Own the roadmap across our customer and partner platform and the internal tooling for pricing, ops and billing.
Spend real time with brokers (the energy consultants who bring us business customers), customers (the businesses we supply) and generators (the renewable sites we buy power from), as well as our own teams. Turn what you learn into sharp problem statements.
Write crisp specs and narratives that make complex things like energy data, pricing, settlement and billing simple.
Prioritise ruthlessly against commercial impact: revenue, win rates and hours saved.
Work hand in hand with our engineering team (~5 engineers), setting direction and giving them the context, clarity and unblocking they need to do their best work.
Prototype ideas and the initial designs yourself with AI tools, testing them before an engineer writes a line of code.
Ship fast, measure outcomes and iterate, keeping quality high.
Align founders, commercial, pricing and ops on the roadmap, the trade-offs and progress, so everyone knows what’s coming and why.
🔌 What you’ll bring
B2B product management experience at an early-stage startup, ideally in complex, multi-stakeholder products. You’ve taken products from 0→1, including the initial design, without a product org, design team or research team around you.
Ideally, experience in a regulated or data-heavy industry such as fintech, insurance, marketplaces or energy, where the product has to handle complex data, rules and multiple stakeholders.
A track record of outcomes, not features: you can point to measurable commercial impact from both external products and internal tools you’ve shipped.
Strong technical and data fluency. You understand data models, APIs and system constraints, and you pull and analyse data yourself (SQL or equivalent).
You relish discovery and can clearly articulate the user insights that changed what you built.
Excellent writing. Your specs and problem statements are simplifying.
Nice-to-haves
Experience shipping AI-powered features or automation
No energy experience? No problem. We’ll get you up to speed.
🔆 Your kind of energy
How we bring the Volter values to life in this role:
Integrity, trust and transparency: You’re upfront about trade-offs and anything that’s slipping. You’d rather say no clearly than overpromise, and you base decisions on evidence, not opinion or gut.
Growth, ambition and excellence: Your specs make the complex simple and what you ship feels considered.
Getting sh*t done: You’ll prototype an idea with AI in an afternoon, ship every week and unblock engineers the same day.
Electric enthusiasm: A knotty pricing or settlement problem excites you, and you bring the team along with you.
Fun and humble: You ask users and engineers before you assume, give the team the credit for what ships, and happily take on the unglamorous work: QA, data pulls, support tickets.
🌱 How we work
We’re together in our Old Street office four days a week, because the best ideas and energy (!) still happen in the same room. You’ll work directly with founders who’ve built and scaled businesses to multi-billion-dollar valuations.
