About the company:

We're on a mission to make a big green dent in the universe by building a truly sustainable energy system globally.

That means making power greener, smarter, and more affordable for everyone.

We put customers at the heart of everything we do: with always-fair prices, transparency and outrageous customer service.

We drive system change: with transformative tech to make renewable energy the norm and end global reliance on fossil fuels.

Octopus Energy Group is made up of 10 businesses spanning 6 countries across 3 continents, including: Octopus Energy Retail, Kraken Technologies, Octopus Energy Generation, Kraken Flex, Octopus Electric Vehicles, and the Octopus Centre for Net Zero. More on OEG @ octopusenergy.group

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 earlier this year, 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're building a small and efficient TechOps Engineering team at Octopus.

We are looking for an ambitious, knowledgeable and experienced Full Stack Software Engineer to join our team, to grow with the rest of the company, and build systems that our people love!You will be a key partner in defining what TechOps Engineering is at Octopus. We will be shaping this team to provide self-service technology that doesn’t currently exist to help our people access, manage and use cutting edge tech on-demand.

What is TechOps?

A more modern, more lean version of a traditional enterprise IT team. The team covers everything from what most people would call “1st line support” all the way up to high-level strategic planning, and everything in between.

We’re looking for a Full Stack Software Engineer to join our TechOps Engineering team, designing and building solutions to make our TechOps capability efficient, scalable and robust and available on-demand via self service.
