Associate Product Manager

About Octopus Energy

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.

Now, we’re scaling fast and building the next generation of products to accelerate the green energy transition.

In 2021, we brought this mission to Japan – the world’s largest liberalised energy market. Here, we are committed to making energy better for both customers and the planet, while driving the growth of green energy across the country by using smart technology.

In our lean and fast-moving team in Japan, every idea and action has the power to create a real impact on both business and society. We’re looking for people who can build scalable, highly resilient platforms from the ground up.

We are looking for an Associate Product Manager to join OE Tech and support the Japan team.

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.

If this sounds exciting, we’d love to chat.
