About the position

As an Expert System Engineer, you will decisively design, implement and maintain our highly available and robust IT infrastructures.

You use your infrastructure as code (Ansible, Terraform) and scripting (Python, Bash) skills to automate processes and improve efficiency. In addition, you contribute to the development and maintenance of monitoring and logging solutions (e.g. Prometheus, Grafana) to proactively identify problems and ensure the continuous functioning of critical systems. This position offers the opportunity to overcome complex challenges, drive innovation and make a significant contribution to our technological landscape.
