Was wir dir bieten

Work with purpose

Our DNA and passion: Linux, open source and data protection. Let's work together to make our customers' communication free, more secure and thus digitally sovereign.



You can expect challenging and varied tasks that always bring new insights. Exchange of experience and knowledge transfer across all teams and levels are a matter of course for us.



We promote your professional and personal development in a targeted manner. An open exchange within the team is just as much a fundamental part of this as internal and external training courses, conferences or coaches.


Code life balance

We make it possible for you to reconcile work and family life - e.g. through flexibility and partial remote working. Oh yes: Overtime is not a matter of course and will of course be compensated.


Family business

We are a family-run company with over 25 years of history. For our culture, this means trusting cooperation, stability and security.



Coffee, tea and fruit are always on hand. Just like regular joint team events and activities that make (working) life more enjoyable.



Then we look forward to receiving your application! Please let us know your earliest possible starting date and your salary expectations. If you have any questions, do not hesitate to contact Susanne Baldin directly: +49 30 405051 79.
