AI in this role
We're making energy fair, clean, and simple for all using technology.
Octopus Energy started with a bold idea: to build Britain’s first truly digital energy supplier. 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.
To deliver on this mission, we are looking for a Senior Data Engineer to join the Flexibility team.
The Flexibility team was established in early 2026, and has been growing throughout the year. The team is focused on greenfield opportunities at the cutting edge of Octopus' flexibility strategy, and aims to enable rapid response to global flex opportunities.
They are building the next generation of products and tools to make energy more flexible. These include our flagship Intelligent Octopus product automating demand shift for 300,000 customers with electric cars, home batteries or smart heating devices, saving 2 million customers money through Saving Sessions and Free Electricity Sessions, and managing 568MW of large grid-scale batteries to balance the system. The team develops products that are used by millions of customers, helping boost renewables use and decarbonise energy systems worldwide.
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.
