Kraken is the technology tentacle of the Octopus Energy Group.
Our mission is to provide cheaper, greener energy to the French market.
Octopus Energy France is a fast-growing energy company recognized as an ESS (social economy). **We offer a better experience to our customers through transparency, honesty and simplicity. We want to do better for the planet, through real, long-term investment in renewable energy production and a low-CO2 future that's better for our customers' wallets. We want to revolutionize the energy business through our people, our platform and our use of data.
Our focus is on customer satisfaction, and receiving positive reviews is important to us - we have the best score among French energy suppliers on Google Reviews and Trust Pilot.

Kraken technologies

Kraken Technologies is a company within Octopus Energy Group who are licensing the Kraken platform and operating model to clients across the world. Current clients are both the Octopus Energy retails businesses around the world as well as external clients such as Good Energy, Origin, EDF, E.ON Queensland Energy - with many more expected to join over the next few years!

Our team

All technology is written and maintained by a multi-discipline engineering team of around 450 people globally. 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.
Some of our coding conventions are open-source.
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.

What you'll do

We have lots of difficult design challenges to solve. The French energy market is complicated, outdated and process-heavy - there's an awful lot of domain modelling that we need to get right. Strong attention to detail is essential.
We have difficult technical problems to solve. With the advent of smart meters, we'll soon be processing millions of meter readings a day. We need the right technology in place to handle this smoothly as well as feeding data into a machine learning pipeline that models and predicts consumption.
You'll be working for a company that’s fighting climate change.
As a supplier, we're helping people to use greener technology and renewable energy, all helping move the French market towards a lower carbon future.

What you'll have

We're looking for someone with a general interest in technology and problem-solving; someone diligent and thoughtful.

It would be helpful to have experience/expertise in the following (in rough priority order):

  • Python (minimum 5 y.e.)
  • Django (or equiv. web framework)
  • Fluent in French, and lever B2 at least in English
  • Domain modelling
  • HTTP and REST APIs
  • Writing robust and fault-tolerant software
  • Celery and async processing
  • Postgres
  • Plus experience in the following would be a bonus:
  • AWS
  • Terraform, Packer, Consul
  • React and Redux
  • This is a full remote position. We are therefore looking for senior developers. We need people working remotely to have a very good level of autonomy and strong technical abilities. If you are not senior, we may have space for you but it will not be in a remote position.

What you'll love about us

  • Wondering what the salary is for this position? Ask us! During our initial contact, this is something we always bring up, because we really want to match your experience with the right salary. The reason we don't talk about it here is that we have a degree of flexibility and would never want salary to be a reason why someone doesn't apply to Octopus - what's more important to us is finding the right octofit!
  • Octopus Energy has a unique culture: we won the award for Best Company to Work For in 2022, on Glassdoor UK we were voted one of the 50 Best Places to Work in 2022 and our CEO, Greg, recorded a podcast about our culture and how we empower our employees. In 2023, we were named one of the 100 best companies to work for in the Sunday Times.In France, we were awarded the Happy at Work label, and ranked eighteenth out of a total of 1,675 structures in the category of companies where employees find the most meaning.
  • We are an organization where people learn, decide and build faster. Where they work autonomously, with extraordinary people, on innovative projects. Profit-sharing, flex-office, excellent mutual insurance, soft mobility package, coverage of part of the "pass navigo" above the legal minimum, and even special days off to invest in an associative project that's close to your heart... we want your investment to be rewarded by benefits you really care about!
  • At Octopus, we're looking for people who are genuinely caring and empathetic. Equal opportunities are important to us, and we're committed to providing an inclusive and fair working environment. We invite you to apply, whatever your age, gender, marital status, color, disability, pregnancy or parenthood, origin, religious beliefs or sexual orientation.

About Octopus Energy

View company profile

We're on a mission to make energy greener, fairer, and genuinely better for people. Our global energy revolution is backed by Generation, the sustainable fund co-chaired by Al Gore. We have thousands of diverse roles ready to be filled across our Group and around the world.

Europe's best-funded green tech start-up

We're one of the few UK 'double unicorns', building cutting-edge technology to drive the global green energy revolution.

Recently we were honoured to receive $600 million investment from Al Gore’s own sustainable investment fund, Generation – a massive vote of confidence from one of the world's foremost climate action leaders.

Transforming the energy system using tech

Our industry-leading tech platform Kraken is revolutionising the energy system to make power cheaper, greener, and better for people. It's licensed to support 17 million customer accounts globally, and we aim to serve 100 million by 2027.

Kraken’s unlocking an energy grid that works like the internet: key to accelerating the world’s transition to a decentralised, 100% green energy system.

The best-loved energy supplier in the UK

We've gone from a tiny startup supplier to a global leader in just 5 years, and through that relentless growth we still put customers at the heart of everything we do. That's how we've got five stars on TrustPilot based on over 100,000 customer reviews and why consumer champions Which? have named us a Recommended Provider for the last five years in a row.

We're fighting to make energy fairer, more affordable, and more accessible for all.

What it's like to work at Octopus

We’ve got an important, urgent mission to bring affordable, green energy to the world, and every person at Octopus works relentlessly to make that change happen fast.

We work with freedom and responsibility. You'll get a lot of trust to run with ideas and take ownership of what you do.

Our founder Greg has a theory that building a great team should be like building a dry-stone wall: rather than forcing people into 'cuboids' and sticking them together in neat little rows, we take authentic humans, and find ways for them to fit together naturally to form a truly solid team full of unique perspectives and strengths. This way of working isn't for everyone. You have to drive your own work forward; be agile, flexible, and personally accountable for everything you do, from idea to conception.
