Senior Product Manager

Senior Product Manager, Rosso

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, 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.

Responsibilities:

• Turn needs into shipped product
• Own the technical-product detail
• Work across complex problems, not one fixed patch

Requirements:

• A technically strong, ML-literate product manager who has worked embedded in full-stack teams that include ML and data science (MLEs, MLOps, DEs and DAs).
• Owned at least one complex product area end to end, with a track record of moving real business outcomes, not just shipping features.
• Uses data analysis throughout the product process, to validate ideas, progress work, and measure success.
• Built product in a startup, scaleup or other high-growth environment, with high personal ownership of an area.
• A strong instinct for failure points, edge cases and the operational reality of a live system.
• AI-native, AI-literate and AI-critical - you know where it helps and where it hurts.
• A clear, structured communicator, especially in writing.

Bonus Points:

• Experience in energy, fintech or another domain where ML is mission-critical, and/or where forecasting or fulfilling a two-sided marketplace is central to the product.
• Experience going through a third-party-access and/or international-expansion transition.
• Experience with regulated industries and data-heavy products.

Benefits & Perks:

• Competitive salary - our current band for this role is £85,000 or equivalent in local currency.
• Stock Options - everyone on the team has ownership in our mission.
• 25 days holiday + public holidays - Swap public holidays for ones that matter most to you. Plus, get an extra day off for your birthday.
• Remote & flexible working - We're fully remote with clear core hours, and no internal meetings on Friday afternoons.
• Home working & wellbeing budgets:
• Up to £1,200 / €1,200 annually to upgrade your remote setup (co-working passes, equipment, etc.).
• Up to £150 / €150 monthly on anything that supports your wellbeing - from therapy to gym memberships to meditation apps.

Interview Process:

1. First call with our Talent Team (30 Mins). This is to understand your experience, motivations, and discuss the role in more detail.
2. Behaviour Interview with our Product Lead (45 Mins). This is your chance to really understand the role, the expectations, and ensure alignment on ways of working.
3. Technical Interview with the Team (75 Mins). You'll meet with potential peers to discuss how you drive product execution, work closely with ML and engineering teams, and think through real product scenarios - built around a real product decision shaped by a model or forecast, so we're testing on proof, not assertion.
4. Culture-Add Interview with Stakeholders (45 Mins). The final session will be with two cross-functional stakeholders, and will explore how your values align with ours, and is designed to be a genuine two-way conversation, your chance to understand what it's really like to work at tem.

We welcome applications from people of all backgrounds, experiences, and identities, including those that are traditionally underrepresented in the tech and energy sectors. If you're excited about this role but not sure you meet every requirement, we'd still love to hear from you. Your unique perspective could be exactly what we're looking for.
