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'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).

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.

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.
