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. From making it effortless to switch to heat pumps, solar and EVs, to launching smart tariffs and creating renewable generation at scale, we’re solving some of the most complex challenges in energy with speed, creativity and customer obsession. We’re also enabling our global businesses to reach the full capability of what we’ve achieved in the UK, taking the learnings, products and experiences that customers love here and rolling them out worldwide.

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.

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

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're building the next generation of products to accelerate the green energy transition. From making it effortless to switch to heat pumps, solar and EVs, to launching smart tariffs and creating renewable generation at scale, we're solving some of the most complex challenges in energy with speed, creativity and customer obsession. Here in Japan we’re following in the footsteps of the UK, taking their learnings, and adopting products and experiences that customers love.

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.
