System Administrator (m/f/d) Infrastructure and IT Security

For over 30 years, Advancis has been developing innovative software solutions for security and building automation. As one of the international market leaders, our solutions are used worldwide in companies, at critical infrastructure facilities, and in complex modern buildings.

As a System Administrator (m/f/d), you will administer systems with a focus on security and a holistic approach – from network planning to tool selection. IT security is an integral part of your work (e.g., Zero Trust, segmentation, SIEM). We are currently establishing our ISMS and preparing for ISO/IEC 27001 certification – therefore, systems are not just operated but assessed based on risk and clearly documented. Experience with ISO 27001 is a plus, but not a requirement – the willingness to think within these frameworks, however, is.
