We are rebuilding the energy transaction system to make it transparent and fair, putting power back into the hands of customers and tackling the critical problem of access to low-cost electricity. Our goal is to fix a broken global energy market that favors legacy operators and opaque pricing. We have built the first AI-native transaction infrastructure to reinvent how electricity is bought, sold, and priced, cutting out inefficient fees, automating complex market flows, and bringing transparency and fairness to energy transactions at scale. Having closed a $75 million Series B funding round, we are positioning for global expansion, deeper product innovation, and category leadership. Our modern utility product, RED, has already facilitated thousands of business customers and billions in energy transaction value. We are rearchitecting market infrastructure for transparency, efficiency, and sustainability.
📈 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.
We’re looking for a Staff Engineer to accelerate product delivery and enable scale across our developer experience and platform engineering initiatives. You’ll contribute through hands-on coding, drive architectural direction, and raise the technical bar across the team.
In your first 12 months, you’ll lead the development of systems and tooling that redefine how engineering teams build, deploy, and operate software - from internal developer platforms and CI/CD workflows to scalable infrastructure and self-serve tooling. You’ll help us improve engineering velocity, reliability, and observability while laying the groundwork for rapid, sustainable growth.
Must-Haves:
Desirable:
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.
