Senior DevOps Engineer

We're rebuilding the energy transaction system, making it transparent and fair.

tem exists to put power back in the hands of people. Today’s wholesale energy market is stacked in favour of the few. It's a product of an age of oil and gas, riddled with markups and middlemen. We’re changing that.

Our product, RED™, built on a proprietary pricing engine that bypasses the wholesale market, enables businesses to buy the energy produced by renewable generators directly. That's 100% transparent transactions, ensuring affordable bills and fair compensation, to give every business ownership and control over where their energy comes from.

Since launching in 2021, we’ve saved UK businesses and generators over £20 million, powering a growing network of forward-thinking companies, from Pizza Pilgrims to Silverstone. Backed by top-tier VCs such as Atomico and Albion, we’re creating a new category in energy - one that’s local, decentralised, and built on trust.
