System Administrator Linux (m/f/d) | in Freiburg im Breisgau

**Do you not just want to administer a Linux System Administrator, but also decide for yourself what a modern Open Source IT landscape should look like?**🚀

Then you'll get the freedom to do so here. Our client is a growing, family-run technology company from Freiburg that develops hardware and software solutions for industrial image processing and automation. Their own systems are currently in use in more than 15,000 machines worldwide.

As a Linux System Administrator, you will strengthen a deliberately small IT department and thus receive a great deal of creative freedom. Instead of rigid corporate structures, you can expect short distances, direct exchange with management, and the opportunity to actively shape technical decisions.

The technological focus is consistently on Linux and Open Source. Exciting topics are on the agenda in the coming years: existing applications are to be migrated to Open Source alternatives, Cyber Security and Resilience are to be further expanded, and our own internal Linux-based AI Server is to be continuously developed.

If Linux is your professional home and you prefer to develop new solutions rather than just keeping existing systems running, you can help shape the IT landscape here long-term.
