Kapten opens a Tech Hub in Barcelona!

We have a lot of great challenges coming around the corner at Kapten - like becoming the European leader in urban mobility 😏 And since we’re a bit crazy... we aim to double the size of our Tech team in the coming months!

How are we going to do that? With YOU. We are convinced that tech enthusiasts are located anywhere around the globe. By opening a Tech Hub in Barcelona, we want to create new opportunities for you and all the amazing talents out there to join us.

Your team:

Starting with a few developers, our Tech team is now composed of 90 people organized in Tribes, Squads, and Guilds in a Spotify-like model.

  • A homemade architecture named Swipr and mainly based on the Clean architecture:
    • Presentation layer using MVVM principles

  • You always push to become a better developer and you mentor junior developers.
