Octopus Energy started in the UK with a bold idea: to become the first truly digital energy supplier. With cutting-edge technology and amazing people who are passionate about customers and the energy transition, we succeeded and today we are one of the UK’s largest energy providers.
In 2020, we took the next step and expanded to Germany. Since then, we have been supplying customers here with electricity and gas – clean, fair, and transparent. Today, we serve over one million energy customers in Germany. At the same time, we are driving the green energy transition forward: from easy switching to heat pumps and smart meters to intelligent tariffs that make everyday life easier.
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. You’ll work side by side with teams across marketing, operations, and data, and see the impact of your work in the real world, fast.
