About Octopus Energy and Kraken

Since 2015, Octopus has been on a mission to bring affordable, green energy to the world. With the help of our in-house developed technology platform, Kraken, we’ve become the 4th largest energy supplier in the UK, opened retailers in 7 other countries, and licensed our software to retail giants including Tokyo Gas in Japan, E.ON in the UK and Origin Energy in Australia. We’ve reinvented energy products with smart, data-driven tariffs to balance customer demand with renewable generation - and we’re the biggest investor in renewable generation in the UK.

We are Kraken Tech Japan
We've since expanded our tentacles and we are now looking for a Senior or Lead Platform Engineer, based in Japan. Specifically, we're looking for someone to join the team and help us build and scale “Kraken”, a cloud-based energy platform for interacting with both consumers (via the web, mobile and smart-meters) and the industry (e.g. data flows, consumption forecasting, trading on the wholesale market).

Our team
All technology is written and maintained by a multi-discipline engineering team of around 500 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, Kubernetes and Terraform Enterprise as part of an immutable-infrastructure, continuous delivery pipeline; and Datadog, Sentry and Cloudwatch to measure performance and monitor production.

Our technology
On the server-side, we mainly use Python. Most of our websites are powered by Django, Django-REST-framework and GraphQL. We use Celery, RabbitMQ and SQS for background processing and have a data platform that uses Pandas, Numpy and Jupyter for analysis and forecasting. We are heavy users of AWS. We host our applications in Kubernetes (EKS) and on EC2 and deploy and manage them with Helm/ArgoCD, or Packer/Terraform. On the client-side, we use React, Redux and SASS with increasing amounts of Next.js; our mobile apps are built using React Native.


What you'll do...

  • Identify, design and lead on initiatives that help us scale
  • Support, maintain and expand our AWS infrastructure
  • Ensure our systems and services are both reliable and performant
  • Collaborate with Developers on new features and services
  • Work with the Security team to ensure that the platform is secure
  • Help solve interesting and difficult problems. There’s a great opportunity for disruption in the global energy market 
  • What you'll have:

  • Excellent Linux skills. Our services run on Linux, so you’ll need to be confident administering and troubleshooting Ubuntu and/or CentOS
  • Good experience with AWS. We use a lot of different AWS services and not just the standard few.
  • Terraform. We use Terraform Enterprise to roll out changes to our cloud
  • Python and Django (or equiv. Web framework)
  • PostgreSQL, or similar RDBMS, particularly in Amazon RDS
  • Docker and Kubernetes. We use Amazon EKS.
  • A good understanding of troubleshooting distributed systems
  • Experience managing and supporting a large scale internet facing service

  • Plus experience in the following would be a bonus:
  • Networking knowledge, particularly routing and VPNs
  • An awareness of security processes and DevOps security tools
  • Experience with RabbitMQ, or other messaging queues
  • Celery and async processing
  • An understanding of Data Science / Big Data tooling and methods
  • What you will love about us

  • Our company culture - We are organisation where people learn, decide, and build quicker. Where people work with autonomy, alongside a wide range of amazing co-owners, on projects that break new ground. We want your hard work to be rewarded with perks you actually care about! We won best company to work for in 2022, on Glassdoor we were voted 50 best places to work in 2022 and our Group CEO, Greg has recorded a podcast about our culture and how we empower our people.
  • Flexible working environment - genuine work life balance here, we are in the top 5 companies in the UK, we treat you as a human, and do our best to make work and life merge smoothly together 
  • Equity Options Scheme - you own your own part of the business, share options in the whole Octopus Energy Group so we all work together towards success 
  • Office - have a certain tech requirement? We’ll do our best to get it. We also have drinks, snacks and a coffee machine at the WeWork office space.
  • Your development is important - we support and help with development including internal and external courses, learning, study support etc, all bespoke to you
