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

Kraken is the technology tentacle of the Octopus Energy Group. 

Kraken Utilities

All technology is written and maintained by a multi-discipline engineering team of around 700 people globally. Our engineers work in ‘super teams’ which are focused on key areas of our platform as well as other innovative products. This also includes server-side, client-side and mobile engineers working closely with UX experts, copywriters and designers. 
 
Teams are empowered to choose a way of working that works for them, often opting for a Kanban-like approach. Notion and Asana are then used to specify and manage work; Github, CircleCI and Terraform Enterprise as part of an immutable-infrastructure, continuous delivery pipeline; and Datadog, Sentry and Cloudwatch to measure performance and monitor production. 

We’re now charging our Kraken platform to power utilities beyond just energy (think water, broadband,..) and have created a new business area Kraken Utilities. Over the last year we have built this team from scratch to re-architect, design, and develop our Kraken software platform to solve complex industry wide problems within the water and broadband sectors (customer experience, water leak detection software). 

The Kraken Utilities team have already signed 4 clients (Portsmouth Water, Severn Trent, Leep, and Cuckoo Broadband), and are currently in the exciting design and build phase of the software. Together with the rest of the team, you will bring the same revolutionary customer experience, operational excellence and speed of innovation that Kraken is powering across energy retailers to other sectors. 

We’re building a team to work fluently, move fast, and make a tangible difference in energy tech. Our current projects span electric vehicles, energy retail, smart home device management, heat pumps, and more. Our projects are ambitious and seek to help both Octopus Energy customers and the clean energy transition.
 
Kraken is a great place to learn, work with some talented engineers and level-up your skills.  

Our Team

We launched our flagship app with a small team of 4 engineers, product, and design in 2021. Since then we’ve grown to multiple cross-functional teams, 18 mobile engineers, and serve over two million monthly active customers in 5 different countries.

We’re expanding to meet the challenges of rolling out a single platform which supports diverse utility markets around the world. Every team member helps define culture and processes necessary to work collaboratively and effectively across multiple product teams, whilst instilling good engineering practices for the team as a whole.
 
Our Technology

As an organisation we like to move quickly. This is true both in how we operate as a business and the technology choices we make. We were very early adopters of Kotlin Multiplatform (KMP) and used the technology when it was in pre-alpha, at scale, to great success. It helps us share code across Android and iOS without the user experience tradeoffs.

KMP was officially released in late 2023 so we don’t expect our applicants to have experience using it. It powers the extensive shared layer across our Android and iOS apps, with UI powered by Jetpack Compose and SwiftUI. Our app is built around MVVM and utilises unidirectional data flow with a layered architecture. Our view models are written using Jetpack Compose and compliment our state driven UI.

We release updates to customers weekly. We gain release confidence with our suite of automation and unit tests running in CI (GitHub Actions), and configure features remotely using feature flags.

Some of our coding conventions are open-source.

This team will require candidates to work on a hybrid remote basis, coming into our office in Oxford Circus 1-2 days a week. You do also need to be able to work in the UK.

We're very excited to be growing our team. We're looking for skills and experience to help shape and define the future of not only our team, but the wider business at a global scale. If you're reading this and grinning, please apply! There are huge challenges to tackle, and we need amazing people who are keen to get stuck in.


If this sounds like you then we'd love to hear from you.

Studies have shown that some groups of people, like women, are less likely to apply to a role unless they meet 100% of the job requirements. Whoever you are, if you like one of our jobs, we encourage you to apply as you might just be the candidate we hire. Across Octopus, we're looking for genuinely decent people who are honest and empathetic. Our people are our strongest asset and the unique skills and perspectives people bring to the team are the driving force of our success. As an equal opportunity employer, we do not discriminate on the basis of any protected attribute. Our commitment is to provide equal opportunities, an inclusive work environment, and fairness for everyone.
