What will you be doing?

Octopus Energy Engineering is responsible for the sites, services, and tariffs that are used by the millions of Octopus Energy customers worldwide. From building the latest, cutting-edge time-of-use tariffs, to helping customers actually enjoy tasks like providing meter readings through our wheel of fortune - and everything in between.

You’ll find a wide variety of challenges in the work we do as we help push the energy revolution forward. Our teams are multi-disciplined and collaborate between countries, meaning you have what you need to get the right people together and build the next great thing.

Octopus Energy is growing rapidly, and the Octopus Energy Engineering team is at the forefront of this expansion. We are looking for a Backend Developer who will work closely with Octopus Energy UK and various teams, focusing on the development and integration of new features for the website and mobile app.

The role involves working on different modules, including the private area, bill management and saving sessions, contributing to customer onboarding optimization and the implementation of marketing projects through dashboards and the personal area.

The team is driven by the mission of creating a direct impact on customers in everything it does, meaning priorities do sometimes change, but the pace and resulting feedback cycle is satisfyingly quick, and consistently so too.

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.
