About this role

Help us use technology to make a big green dent in the universe!
Kraken powers some of the most innovative global developments in energy.
We’re a technology company focused on creating a smart, sustainable energy system. From optimising renewable generation, creating a more intelligent grid and enabling utilities to provide excellent customer experiences, our operating system for energy is transforming the industry around the world in a way that benefits everyone.
It’s a really exciting time in energy. Help us make a real impact on shaping a better, more sustainable future.

Our team
All technology is written and maintained by a multi-discipline engineering team of around 1400 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 and CircleCI as part of an immutable-infrastructure, continuous delivery pipeline; and Sentry and Cloudwatch to measure performance and monitor production. Kraken is a great place to learn, work with some talented engineers and level-up your skills. Some of our coding conventions are open-source .
Engineering standards are high. We pair program, thoroughly review and test code before it deploys, and maintain fast, high-value test suites. We have weekly tech talks, monthly blitz-days (eg sharpening our internal tools, upgrading dependencies) and can often be found at tech meet-ups and conferences.
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 (which we've recently upgraded to 6.0.2), Django-REST-framework and GraphQL (Graphene). We use AWS heavily as part of a continuous deployment pipeline. See, for example, Django, ELB health checks and continuous delivery.

What you'll do

  • We have lots of difficult design challenges to solve. The Japanese energy market is complicated, outdated and process-heavy - there's an awful lot of domain modelling that we need to get right.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.
  • There's a great opportunity for disruption in the Japanese energy market. The energy landscape is changing as we move to more dis-aggregated forms of generation, with less predictability, more dynamism and smarter technology. Octopus Energy were the first UK supplier to introduce a "tracker" tariff whose prices track the daily wholesale prices: http://www.cleanenergynews.co.uk/news/efficiency/octopus-offers-transparency-with-wholesale-price-tariff
  • You'll be working for a company that’s fighting climate change. Our parent company is the largest investor in solar generation in the UK, and are funding wind and anaerobic digestion. As a supplier, we're helping people to use greener technology and renewable energy, all helping move the UK towards a lower carbon future.

    • What you'll have
