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 800 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.

Our coding conventions are open-source and we maintain a tech blog.

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 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 The Japanese energy market is complicated, outdated and process-heavy - there's an awful lot of domain modelling that we need to get right.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

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

Django (or equiv. web framework)

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
