Team Studyflow

We’re a small team (2 developers & 1 designer) so you will have the opportunity to have a lot of impact, and to learn from peers who are extremely talented engineers, and interface designers. Our back-end is written in Clojure, a JVM-based LISP that is a dream to work in. We expect the following:

  • You are a team player who enjoys discussing ideas and implementations with other engineers.

  • You recognize that we are all stewards of the codebase, not owners. You leave code better than you found it, and you fix bugs without grumbling about whose they are.

  • You are open-minded to feedback, and have an eagerness to learn and improve yourself.

  • You are serious about the art of programming. You put pride in your work while continuously striving to combine the beautiful with the highly usable.

Although most of our team is based in Amsterdam, we allow remote work. Our communication takes place through Slack, Skype and Asana.
