Senior Backend Developer
London, UK /
Kraken Technologies 📈 – Backend Development /
Kraken is the technology behind Octopus Energy.
All technology is written and maintained by a multi-discipline engineering team of around 300 people globally. Our engineers work in ‘super teams’ which are focused on key areas of our platform as well as other innovative products. This also includes server-side, client-side and mobile engineers working closely with UX experts, copywriters and designers.
Teams are empowered to choose a way of working that works for them, often opting for a Kanban-like approach. Notion and Asana are then used to specify and manage work; Github, CircleCI and Terraform Enterprise as part of an immutable-infrastructure, continuous delivery pipeline; and Datadog, Sentry and Cloudwatch to measure performance and monitor production.
Some of our coding conventions are open-source .
Kraken is a great place to learn, work with some talented engineers and level-up your skills.
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.
Client-side, we use React, htmx 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 The UK utilities market is complicated, outdated and process-heavy - there's an awful lot of domain modelling that we need to get right.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 challenging technical problems to solve; like processing tens of 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. Or thinking about how we adapt Kraken to improve other utilities like water and broadband.
- There's a great opportunity for disruption in the UK energy market. The big suppliers still dominate, but are not exactly popular. The energy landscape is changing as we move to more dis-aggregated forms of generation, with less predictability, more dynamism and smarter technology.
- You'll be working for a company that’s fighting climate change. Our generation arm is the largest investor in solar generation in the UK, and is 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.
- As a senior engineer you should be comfortable owning a domain and leading the response to a platform outage if necessary
What you'll have
- We're looking for someone with a keen 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):
- Django (or equiv. web framework)

- Plus experience in the following would be a bonus:
- Terraform, Packer, Consul
