Kraken is the technology behind Octopus Energy. 
We invented, designed and built Kraken Technologies to ensure that we had the most innovative, data-centric and customer-focused technology to support our top-class customer service. Kraken Technologies now delivers transformational Energy-Tech to businesses around the world to make the global transition to green energy quicker and more affordable.
We’re now licensing Kraken Technologies to businesses globally. You can read about our partnership with E.On HERE as an example to see how Kraken is evolving our business. You can learn more about how the migration works in practice HERE.
Our aim is to have 100 million customers on the Kraken Platform by the year 2030.
Our group includes Octopus Energy, Octopus for Business, Octopus Electric Vehicles and Octopus Energy Services as well as our new net zero Centre – Octopus Centre for Net Zero. 
We recently secured over £500 million of investment from Origin, Australia’s largest Energy Company andTokyo Gas, to help us continue our mission.  This will help power our growth into new markets, invest in Kraken Technologies, build more tech to make energy greener and increase our investment in service and growth in our existing markets, the UK and Globally.
Our team
All technology is written and maintained by a multi-discipline engineering team of around 100 people. This includes server-side, client-side and mobile engineers working closely with UX experts, copywriters and designers.
We follow a Kanban-like approach, using Google docs and Asana to specify and manage work; Github, CircleCI and Terraform Enterprise as part of an immutable-infrastructure, continuous delivery pipeline; and Loggly, Sentry and Cloudwatch to measure performance and monitor production.
Octopus is a great place to learn, work with some talented engineers and level-up your skills.
Our technology
On the server-side, we mainly use Python. Most of our websites are powered by Django, Django-REST-framework and GraphQL (Graphene).
We use AWS heavily, employing most of the “Hashistack” (eg Packer, Consul, Terraform) as part of a continuous deployment pipeline. See, for example, Django, ELB health checks and continuous delivery.
Client-side, we use React, Redux and SASS; our mobile apps are built using native code or React Native.
