Senior Product Manager - Trading

📈 Who We Are: We are rebuilding the energy transaction, making it transparent and fair. Our goal is to put power back where it belongs, in the hands of customers and to take on one of the most critical problems of our century, access to low cost electricity. tem exists to fix a broken global energy market that’s long favoured legacy operators, intermediaries, and opaque pricing. Today’s electricity system was not designed for rapid decarbonisation, AI-driven efficiency or fair access for the actual users - businesses and generators. We’ve built the first AI native transaction infrastructure to reinvent how electricity is bought, sold and priced. Our technology is designed to cut out the inefficient fees, automate complex market flows, and bring transparency and fairness to energy transactions at scale. In late 2025, after extraordinary growth, we closed a $75 million Series B - led by Lightspeed Venture Partners with participation from Albion, Atomico, Allianz, Hitachi Ventures, Hitachi Ventures, Schroders Capital and others - positioning us for global expansion, deeper product innovation and category leadership. We’re scaling internationally and building toward a future where AI-driven infrastructure is foundational to electricity markets worldwide. Since launch, our modern utility product, known as RED, has already facilitated thousands of business customers and billions in energy transaction value, proving that modern software and AI can transform an industry built on legacy systems. At tem, we’re not just building another energy company, we’re rearchitecting market infrastructure so that transparency, efficiency and sustainability become the default, not the exception. The Role: We're hiring a Senior Product Manager, Rosso. This is the second product manager on Rosso, reporting into the Rosso Product Lead. Rosso is deeply technical, built on ML-led models and complex engineering covering forecasting, pricing optimisation and portfolio balancing, so this is a role for a technically-minded PM who's happiest closest to the hardest problems. You'll work on complex, important problems as they arise across the Rosso product surface, alongside the other PM on the team, rather than owning one fixed patch. In the near term that means the portfolio area: fulfilling and balancing a growing two-sided portfolio, managing imbalance, and finding the revenue and margin in every position we hold. It's still forming, it carries live financial risk, and it needs someone who wants to win in it. You will: • Take business and customer needs and turn them into feasible, shipped product, working closely enough to the ML and forecasting work to make good calls on it. • Own the technical-product detail, setting clear success criteria for how well a model or forecast needs to perform, and designing for the edge cases and operational reality of a system carrying live financial risk. • Drive open product decisions to a close - yours and the team's - so delivery keeps moving at pace, with a clear Now, Next and Future for the initiatives you own. 🚀 Responsibilities: Turn needs into shipped product • Take business and customer needs and turn them into feasible product execution, balancing them against nascent ML and forecasting innovations that push the frontier of what's possible. • Take initiatives from discovery through to regularly released product, with a clear Now, Next and Future for a given area. • Drive open product decisions to a close, so work keeps moving. • Decide what to formalise, what stays a prototype and what to drop - be the editor and builder, not just the instigator. Own the technical-product detail • Work embedded in full-stack teams that include ML/data science and software engineers, close enough to the models to make goo
