Kraken technologies
Kraken Technologies is a company within Octopus Energy Group who are licensing the Kraken platform and operating model to clients across the world. Current clients are both the Octopus Energy retails businesses around the world as well as external clients such as Good Energy, Origin, EDF, E.ON & Queensland Energy - with many more expected to join over the next few years!
Our team
All technology is written and maintained by a multi-discipline engineering team of around 450 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 and Terraform Enterprise as part of an immutable-infrastructure, continuous delivery pipeline; and Loggly, Sentry and Cloudwatch to measure performance and monitor production.Some of our coding conventions are open-source.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 and the Django-REST-framework. We also use Pandas, Numpy and Jupyter for analysis and forecasting, plus Celery, RabbitMQ, SQS and Airflow for background processing.
We use AWS heavily, employing most of the "Hashistack" (eg Packer, Consul, Terraform) as part of a continuous deployment pipeline. See, for example, Django, ELB health checks and continuous delivery.
Client-side, we use React, Redux 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 The utilities market is complicated, outdated and process-heavy - there's an awful lot of domain modelling that we need to get right.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 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, 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.
• Develop core product features and shape the technical foundation.
• Lead initiatives that drive positive change and improvements.
• Promote collaboration, knowledge sharing, and effective communication across teams.
• Resolve critical bugs and incidents, driving efficiency and improvement.
• Mentor and onboard team members, supporting their growth and performance.
• Address monitoring gaps and handle escalations independently.

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), Spark/PySpark/Databricks, Domain modelling, HTTP and REST APIs
• Writing robust and fault-tolerant software
• Celery and async processing, Postgres, GraphQL.
• Please mention language requirements i.e Spanish, Japanese, Italian, French or any other language in a region we operate.
Plus experience in the following would be a bonus:
• AWS
