Our Kraken TeamAll technology is written and maintained by a multi-discipline engineering team of around 500 people globally. Our engineers work in ‘super teams’ which are focused on key domains 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 talented engineers and have a lot of fun.

What you'll doYou will be joining the Global Industry team! The team focuses on the Energy Industry in Germany, and how we can provide the best client experience while working closely with the local regulations.

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 The utilities market is complicated, outdated and process-heavy - there's an awful lot of domain modelling that we need to get right.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 across 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 love this role if you’re excited about coding a lot, in close collaboration with your highly experienced peers as part of a truly global team. You’ll ensure clean software design, choice of right technologies, and participate in building an application to very high standards that is designed for tremendous global impact.

As the team will grow, you’ll onboard other team members, ensure good documentation, clean code and contribute to establishing a great developer experience.

You'll be working for a company that’s fighting climate change.

As a SaaS company, we're helping people to use greener technology and renewable energy, all helping move the energy market towards a lower carbon future.
