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 young team, <20 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.

Our technology
For the KrakenFlow web app, client-side we use NextJS (React), TypeScript, Zustand, and React Query to connect to our OpenAPI internal REST API, which is fully typed incl. code-gen for type generation.
Server-side, we mainly use Python & Django.
We use AWS heavily, employing most of the Hashistack (eg Packer, Consul, Terraform) as part of a continuous deployment pipeline.

What youll 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.
