Our team

While Kraken Technologies is written and maintained by a 800+ people strong, multi-discipline engineering team, you’ll be part of a new, early stage product division within: KrakenFlow.

KrakenFlow is a team of 35 people in size, and responsible for the development of an end-to-end business process management platform. The new web-based tool allows internal teams and clients to configure, execute, and track their business processes, with a drag-n-drop workflow builder at its core. This is a unique opportunity to marry early-stage challenges with the benefits of the highly successful scale-up that is Kraken.

We work agile and use tools like Notion, Asana, and Figma to specify & plan our work; Github, CircleCI and Terraform Enterprise as part of an immutable-infrastructure, continuous delivery pipeline; 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.

What you'll do

You’ll be a core contributor to the KrakenFlow workflow management experience, delighting users with powerful features around our drag-n-drop workflow builder, form builder, as well as management & analytics pages that are part of the user-facing platform.

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