By combining world-class tech with brilliant humans who care deeply about customers and driving the renewable energy transition, we made it happen and in 2025, we became Britain’s largest energy supplier.
Octopus Energy Group is a global energy transition collective. 10 businesses working across 4 continents to tackle energy transformation at nearly every front.
And we constantly push to make energy better. Tirelessly campaigning for fair protections for customers. And building innovative technologies that forge a path to a green energy system.
We’re made up of 10,000+ authentic, committed people working around the world on stuff you'd never expect. We're united by a shared goal: to drive the global green energy revolution. Read our Spotlight series to meet some of the team.
About the role
At Octopus Tech, you’ll have real ownership, variety, and the chance to shape products that make a tangible difference in people’s lives - lowering bills, enabling greener living, and delivering experiences customers genuinely love.

We are looking for a Frontend Engineer to join our Onboarding team.
The Onboarding team owns the main entry points of consumers for OEGB, focusing on improving the current journeys and working in new projects impacting thousands of customers everyday. They work in a very open and fast-moving environment, focusing on the user experience with a strong human touch to everything they do. Onboarding is also a very collaborative team, working together with other developers and teams, strengthening our tech stack and influencing which paths OE takes in its tech journey.
We embrace flat hierarchies and an open, agile culture that fosters innovation, flexibility, and creativity.
We don’t hang our personalities up with our coats and nor should you. At Octopus, we hire great people who get stuff done, all whilst being themselves.
If this sounds exciting, we’d love to chat.
