Job description

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 create the technology that redefines utilities and unlocks a new energy system of the future. By optimising renewable generation, building a more intelligent grid, and empowering utilities to deliver an exceptional customer experience, our operating system is transforming the industry worldwide.

It’s an incredibly exciting time to work in energy. Join us on our mission to improve the lives of ONE BILLION humans within the decade and shape a cleaner, better future for everyone.

Where you'll fit in:

Kraken’s technology is written and maintained by a multi-discipline engineering team of around 1,400 people globally, which includes server-side, client-side, and mobile engineers. We follow an agile way of working, where individual teams are given the freedom to choose the tools that are most appropriate for managing their work.

Kraken is a great place to learn, work with talented engineers and level-up your skills. Some of our coding conventions are open-source.

Our technology

Our backend developers use Python. Most of our websites are powered by Django and GraphQL (Graphene). Our CircleCI CI/CD pipeline runs tens of thousands of tests, deploying into AWS EKS defined by Terraform over 100 times per day and observed with tools like Sentry and Datadog. This allows us to move fast and at scale, without compromising reliability. Teams work differently but the commitment to quality is the same.

Developers at Kraken are empowered to use cutting-edge AI tools and models. Any generated code is still owned by a human.

What we do

Kraken Engineering has multiple disciplinary groups with their own management structures and teams working together to create a unified Kraken that can be deployed to any territory in the world to achieve clients’ goals.

Client Engineering is the development arm responsible for making sure our clients receive the best possible experience and their needs are met with high quality solutions.

What you’ll own

• We have lots of difficult design challenges to solve. The French energy market is complicated, outdated and process-heavy - there's an awful lot of domain modelling that we need to get right.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.
• You will be working in a multi-disciplinary software engineering team; solving design challenges; domain modeling; solving technical problems; engineering solutions for smart meters, writing robust fault-tolerant software primarily in Python and Django, Celery, and async processing
• 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 French 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.

What you bring to the party

• Python (minimum 7 y.e.)
• Django (or equiv. web framework)
• Fluent in French, and level B2 at least in English
• Domain modelling
• HTTP and REST APIs
• Writing robust and fault-tolerant software
• Celery and async processing
• Postgres

Bonus points

• AWS
• Terraform, Packer, Consul
• React and Redux
