Senior GTM Product Marketing Manager
tem · United Kingdom
📈 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.
🚀 The Role
We’re hiring a GTM Senior Product Marketing Manager who wants to take our product from 1-100, not 0-1 scale.
You will join the fastest growing unit inside tem. This team is obsessed about growing our SMB customers and transforming their perception of energy beyond the bill, so we can hand more money and value back in their hands.
You will be a hands-on product marketer who can bring sharp judgment and voice of customer consistently back to the table. Your focus is to grow the trial, adoption and experience of our RED product and be ruthless in those goals. Expect to solve problems on your own and with product, content and engineers whilst running your own team of expert GTM agents.
Good looks like? Every 48 hours you’ll be:
Speaking to a customer.
Shipping a campaign with Claude.
Launching a piece of work that directly solves a customer problem.
Showing the goals move forward.
You’ll be 20% in architecting, 80% in delivery.
🛠️ Responsibilities
User research: take control of it.
Assets: design and prototype assets to wow and educate our customers.
