Responsibilities

Running and evolving our networks
You’ll ensure the stable and secure operation of our Layer 2/3 networks – and actively shape their evolution. Your main focus will be on modern data center networks based on Cisco ACI. You'll also be responsible for administering firewalls from top vendors like Fortinet, Palo Alto, and Cisco.

Troubleshooting and performance tuning
When things get complex, you dive into 3rd-level support, analyze network issues, and develop sustainable fixes. You’ll also handle performance analysis and contribute to the ongoing optimization of our network environment.

Shaping architecture and evaluating tech
You’ll help drive the development of TU Graz’s network architecture and assess new technologies with a critical eye toward security, scalability, and compliance.

Automation with purpose
Repetitive tasks? You automate them using tools like Ansible or Terraform. You write scripts (Python, Shell, etc.) to streamline, control, and integrate network processes efficiently.

Sharing knowledge and documenting clearly
You keep our technical documentation clean and understandable. You support knowledge transfer within the team and help new colleagues get up to speed, acting as a go-to person for network expertise.

Collaboration across the IT landscape
As a key contact for network operations, design, and security, you’ll work closely with other IT teams, align on technical matters, and contribute to interdisciplinary projects.
