The job is based in Hannover, the capital of the German state of Lower Saxony. While most of the work will be done in our head office in Hannover, it may happen that you work for short-term customer projects in Europe, Mexico, Canada, and elsewhere in the world.

You will get paid to work on and with OpenBSD. We do not use GNU/Linux, Solaris, Windows or any other BSDs but our customers do. In contrast to other vendors of BSD-based appliances, we contribute our code to the OpenBSD project whenever possible (if it fits into the project and with the exception of our system management software). And, of course, you will work close to a big data center.
