Staff Engineer, Software Engineer

📈

Who We Are:

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.

We’re looking for a Staff Engineer to accelerate product delivery and enable scale across our customer acquisition and customer success platforms. 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 that redefine how brokers, customers, and internal teams interact with energy services - from real‑time pricing workflows to intuitive self‑serve tools. You’ll help us launch new products that streamline onboarding, improve service transparency, and lay the groundwork for rapid, sustainable growth.

  DB).

• Front‑end capabilities: Skilled in developing responsive, performant front‑ends using modern JavaScript frameworks such as React.

• Product‑minded mindset: Experience working closely with product and design teams to solve user problems, not just deliver features.

• Can deal with ambiguity: Comfortable navigating changing priorities and incomplete information to make strong technical decisions.
