Role Overview

• Design, implementation and operation of hybrid IT architectures (traditional Windows servers, Linux platforms, virtualization, containers)
• Support and further development of virtualized environments (e.g. Hyper‑V, VMware, LXD), including GPU‑accelerated systems
• Operation and integration of container platforms (e.g. Docker / Kubernetes / MicroK8s) for modern application architectures
• Ensuring high availability (HA), scalability and performance for business‑critical systems
• Planning and maintenance of modern network architectures including segmentation, updated connectivity and firewall rules
• Participation in on‑call rotations to ensure stable operations
• Willingness to travel for project‑ and site‑related assignments
• Configuration, operation and hardening of firewalls, VPN solutions and remote access systems
• Integration and operation of modern cyber security tools, including:
• Backup and recovery solutions (e.g. VEEAM)
• Endpoint and server security (online and offline antivirus concepts)
• Patch and vulnerability management (online / offline)
• Support for security‑by‑design approaches in new architectures (containers, microservices, platform services)
• Performing technical risk and vulnerability assessments in distributed system landscapes
• Installation, configuration and operation of Windows and Linux systems (e.g. Ubuntu LTS)
• Administration of traditional Microsoft infrastructures (Active Directory, GPOs, client/server)
• Participation in next‑generation architecture reviews (e.g. additional nodes, licensing, scaling)
• Documentation, quality assurance and standardization of IT and security processes
