Jobbeschreibung

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 Kraken Team

All 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.

What You'll Do

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.

What you’ll need:

• Fluency and good communication in English and German, French, Italian or Spanish is a plus
• 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: You should have solid knowledge and experience in Python development to create efficient and scalable backend solutions
• Django (or equivalent web framework): You have worked with Django or an equivalent web framework to support and accelerate web application development
• Domain modeling: You possess competence in domain modeling and implementing these models into effective backend structures to support complex business logic
• HTTP and REST APIs, as well as GraphQL: You have in-depth understanding and hands‑on experience in developing and implementing both REST and GraphQL APIs, ensuring efficient communication and flexibility between frontend and backend systems
• Writing robust and fault‑tolerant software: You can write robust and fault‑tolerant software that runs smoothly and reliably even under adverse conditions
• Celery and async processing: You have gained experience with Celery and asynchronous processing to efficiently handle tasks in the background and optimize backend performance
• Postgres: You have knowledge and experience in working with Postgres to develop and manage database applications that meet scalability, performance, and data integrity requirements
