Customer Success 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.

At tem, we’re rebuilding energy from the ground up—starting with total transparency in how power is bought and sold. Now, we’re looking for a Customer Success Manager to help us grow and serve our generator community with empathy, strategy, and operational excellence.

You’ll be working closely with our Customer Success Lead and CMO, with the chance to shape how we deliver value to one of the most important parts of our ecosystem: our generators.

Why this role matters:

Our generator community powers everything we do. Your work ensures they feel valued, understood, and set up for success. In this role, you’ll define the experience of being a supplier on tem—and help us become the trusted engine powering the world’s energy transactions.

Your initial focus will be getting quickly up to speed with our current generator customers today, visiting our key strategic customers, working out their biggest gaps in the customer journey with a plan to solve them, and creating a framework to take us into 2026 growth.

• Take the core customer success playbook and adapt for the generator customer; this includes strategic customer mapping, design and run playbooks, and optimise adoption and advocacy.

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

• Help define and measure what great customer experience looks like at tem—today and into 2026.
