📈 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 scale and serve our rapidly growing business customer base with commercial excellence, genuine customer care, and a relentless bias to action.
You'll be working closely with our Account Management Lead and VP of Sales, owning the business customer lifecycle from onboarding through to renewal and expansion, across our 3500+ SMB customers and our emerging Enterprise segment.
Why this role matters:
Our business customer portfolio is scaling rapidly, already 3,500+ SMB customers and growing ~5x per year. Account Management is evolving into a commercial engine: driving retention, expansion, and NRR through signal-led plays and scalable programmes. At the same time, we're targeting ~15% of revenue from Enterprise customers by year end. In this role, you'll help define what great account management looks like at scale, balancing data, automation, and the human touch.
Your initial focus will be:
Must-haves
Nice-to-haves
We review salaries twice a year using real-time market data, with transparent, consistent pay for the same role and level.
Up to £1,200 / €1,200 annually to upgrade your remote setup (co-working passes, equipment, etc.).
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.
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.
