Job Description

For more than 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 businesses, critical infrastructures, and complex building environments.

As a System Administrator (m/f/d), you administer systems with a strong focus on security and take a holistic approach, from network design to selecting the right tools. IT security is an integral part of your mindset, including concepts such as Zero Trust, network segmentation, and SIEM. We are currently building our Information Security Management System (ISMS) and preparing for ISO/IEC 27001 certification. This means that systems are not only operated but are also assessed based on risk and documented in a transparent and traceable manner. Experience with ISO 27001 is an advantage but not a requirement. However, a willingness to think and work within this framework is essential.
