Account Manager: Business 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 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: - Taking ownership of the onboarding-to-renewal motion and identifying where commercial value is being left on the table. - Helping evolve renewals from time-based cycles to signal-led plays driven by customer usage and adoption data. - Building scalable AM playbooks that work across a high-volume SMB portfolio while supporting early Enterprise growth. 🚀 RESPONSIBILITIES - Be the primary point of contact and trusted advisor for a portfolio of SMB business customers, while supporting early Enterprise accounts with higher-touch engagement, particularly at the crucial onboarding juncture. - Own retention, expansion, and renewal performance across the portfolio, with a clear commercial understanding of ARR, NRR, and what drives growth above 100% NRR. - Identify gaps across the customer journey, from onboarding through to renewal, and design scalable, high-impact improvements (including 1:many onboarding for SMB and tailored 1:1 for Enterprise). - Work cross-functionally across CX, Product, Ops, Commercial, and Marketing, 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 understand the critical product usage path that predicts renewal, and translate it into proactive intervention and expansion strategies. -...
