Customer Success 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 a Customer Success Manager to help us scale and serve our rapidly growing business customer base with empathy, strategy, and operational excellence.

You’ll be working closely with our Customer Success Lead and team, and the Commercial team, with the chance to shape how we deliver value to one of the most important parts of our ecosystem: our 2,500+ SMB customers—and our emerging Enterprise segment.

Why this role matters:

Our business customer portfolio is scaling rapidly—already 2,500+ SMB customers and growing ~5x per year. With a dedicated Customer Experience Specialist squad now in place to love the customer in their inbound moment of need, Customer Success is evolving into a scalable, signal-driven retention engine. At the same time, we're beginning to move into Enterprise, aiming for ~16% of revenue to come from Enterprise customers by the end of the year. In this role, you'll help define the experience of being a business customer with tem—designing scalable onboarding, data-informed renewals, and playbooks that ensure we attain our ambitious 2026 growth plan.

Your initial focus will be:

• Helping to reinvent the end-to-end onboarding motion from the perspective of the crucial human, CS led elements (think 1:many for SMB, 1:1 for Enterprise).
• Helping evolve renewals from time-based cycles (e.g. T-120 days) to signal-led renewal plays driven by customer data.
• Shaping scalable playbooks for a high-volume portfolio while supporting early Enterprise growth.
