Account Manager: Generator Customers

📈 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.

Now, we're looking for an Account Manager to grow and serve our generator community with genuine care, commercial sharpness, and a bias to action.

You'll be working closely with our Account Management Lead and VP of Sales, owning the generator customer lifecycle from onboarding through to renewal, expansion, and long-term advocacy.

Why this role matters:

Our generator community powers everything we do. Your work ensures they feel valued, understood, and commercially well-served. In this role, you'll define the experience of being a supplier on tem, actively driving retention, expansion, and renewal across the portfolio, while building the playbooks and processes that help us scale through 2026.

Your initial focus will be:

• Getting quickly up to speed with our current generator customers and visiting key strategic accounts.

• Identifying the biggest gaps in the customer journey, from onboarding, expansion, through to renewal, with a plan to close them.

• Creating a retention and expansion framework that sets us up for growth.

• Be the primary point of contact and trusted advisor for generator customers, from onboarding through to renewal and expansion.

• Build strong, proactive relationships with UK generators, solving blockers, unlocking commercial opportunities, and owning retention, expansion, and long-term value.

• Identify gaps across the customer journey and design scalable, high-impact improvements.

• Work cross-functionally across Product, Ops, Sales, and Marketing to resolve client issues fast, taking a project management role when multiple departments are involved and sharing the customer voice internally (the good and the bad).

• Interpret usage and adoption data to identify at-risk accounts, expansion opportunities, and the signals that drive commercial outcomes.

• Handle tough client situations with transparency and customer-centricity: explain the problem, the steps, and progress as you go.

• Help build the generator AM playbook from the ground up, including strategic account mapping, scalable onboarding, renewal motions, and expansion plays.

• Travel to visit key accounts and deeply understand the pulse of the generator community.

• Help define and measure what great looks like for generators on tem, today and into 2026.

Must-haves

• Proven experience in account management or customer success in fast-moving B2B environments. You're building and improving, not caretaking.

• Strong commercial instincts: a genuine understanding of how to drive expansion above targets through proactive relationship management.

• A bias to action and willingness to go the extra mile. You move fast, make things happen, and love the customer.

• A deep understanding of what exceptional customer experience looks like, and a consistent track record of delivering it.

• Fluency in CRM tools (e.g. HubSpot) and the ability to translate usage, adoption, and commercial data into clear actions.

• Excellent communication and listening skills, with the ability to work cross-functionally and carry the customer voice into internal conversations.

• Comfort operating at high velocity, managing hundreds of accounts and renewals with rigour and care.

Nice-to-haves

• Experience working with B2B supply-side customers, particularly in energy or marketplace businesses.

• Exposure to early-stage or high-growth tech startups.

• A strong desire to challenge the status quo and change how things work, not just how they're supported.

• Achieve and maintain an NPS score of 80+ across the generator community.

• Drive strong retention and net revenue retention (NRR) through proactive renewal management and expansion plays.

• Embed a clear generator AM playbook, from onboarding through to renewal and expansion, with defined escalation paths and minimal manual overhead.

• Ensure every generator account has a documented account plan with active monitoring for risk and clear commercial mitigation actions in place.

• Competitive salary - We review salaries twice a year using real-time market data, with transparent, consistent pay for the same role and level.

• 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.

Our processes normally take around 2-3 weeks from first call to offer — please let us know about any adjustments to timelines that may be required.

• Intro call with Talent, 15 minutes.

• Hiring Manager interview, 30 minutes.

• Take-home task: a practical challenge that tests your ability to approach the real world challenges of the role.

• Skills interview: present your take-home task and walk us through your thinking. 60 minutes.

• Culture Add interview with leadership stakeholders.

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.
