Why work with us
-
You may hear it frequently from leaders at DNA that they would like to attract people smarter than themselves. Leaders at DNA feel responsible for creating an environment in which self-motivated people build teams that are able to create great things.
-
The source of productivity comes from a team having clearly defined autonomy and responsibility, not from micro-managing people.
-
We believe that diversity and psychological safety at work matter — we get proofs of that everyday.
-
Usually, the problems we are trying to solve are complex (not complicated). Frequently, it means that we follow the Agile process and build our organisation according to the DevOps model.
Join a team with great autonomy and responsibility. The team discusses business priorities with the Product Owner, defines architecture, technology stack, way of working, takes pride in engineering craftsmanship and is end-to-end responsible for the solution.
