Jobs

How do we work?

We are organized around fairly simple rules. You own the thing you are responsible for. We work remotely. We communicate asynchronously. We have quarterly meetup somewhere in Europe where we have fun and discuss strategic topics.

This setup requires strong communication skills, both spoken and writen. We do not want to work with people pleasers nor rock-stars/primadonnas. Be humble and strive for excellence and you will love it here.

How to apply?

Write email to jobs@rolken.cz with name of the position and attach your CV. You might say few words about you – empty email with CV is weird. If you prefer not to write anything, that is OK too. Just state what you want. 🙂

Before you apply here are prerequirements:

  • EU citizenship or residence in EU/Schengen/EEA country;
  • No criminal record.
