The Opportunity

An established international technology organisation is looking for a hands-on IT System Specialist to join its internal network infrastructure team in Munich.

The position will focus primarily on the operation, administration and troubleshooting of LAN, WLAN and firewall infrastructure across a growing international environment.

This is a mid-level operational position rather than a senior architecture or leadership role. It is suited to someone with approximately three to five years of practical network administration experience who enjoys remaining close to the technology.

Your Responsibilities

• Operate, maintain and administer the company’s network and firewall infrastructure.
• Support LAN, WLAN, switching, routing and gateway environments.
• Administer Aruba switching and wireless technologies.
• Monitor network availability, stability, performance and security.
• Analyse and resolve network faults and connectivity problems.
• Configure and support network access-control solutions.
• Implement and maintain colorless port configurations.
• Administer Palo Alto and FortiGate firewall environments.
• Implement approved firewall rules and network changes.
• Process second-level incidents, service requests and changes.
• Use Wireshark and other tools to analyse network traffic and troubleshoot technical issues.
• Support DNS and network services within a multi-site environment.
• Document configurations, changes and troubleshooting outcomes.
• Contribute to ITIL-aligned processes, standards and operational guidelines.
• Support the deployment of the company’s established network architecture at new international locations.
• Occasionally travel to other sites to assist with network implementation and infrastructure rollouts.

Technical Environment

The network environment includes:

• Aruba switching and WLAN
• Palo Alto firewalls
• FortiGate firewalls
• Infoblox DNS
• Genua firewalls
• Wireshark
• Network access control
• Colorless ports
• LAN/WAN infrastructure
• TCP/IP
• VLANs and network segmentation
• DNS and DHCP
• VPNs, routers, switches and gateways
• Network monitoring platforms
• ITIL-based incident, request and change management

Applicants are not expected to have experience with every technology listed. The strongest priority is practical LAN/WLAN administration, ideally with Aruba, supported by experience with Palo Alto or FortiGate firewalls.

Your Profile

• Approximately 3–5 years of hands-on network administration experience.
• Strong practical knowledge of LAN, WLAN and enterprise switching.
• Experience working with Aruba switching or wireless infrastructure is highly desirable.
• Practical firewall administration experience, ideally involving Palo Alto or FortiGate.
• Experience monitoring and troubleshooting modern IT networks.
• Familiarity with network access control and network segmentation.
• Ability to analyse network traffic using Wireshark.
• Experience handling second-level incidents, service requests and technical changes.
• Completed vocational IT training, ideally as a Fachinformatiker für Systemintegration, or a comparable technical qualification.
• Fluent/C1 German.
• Professional English communication skills.
• Proactive, independent and team-oriented working style.
• Willingness to work onsite in Munich three days per week.
• Eligibility to work within a security-sensitive IT environment.

• Hybrid working with three onsite days per week.
• Flexible working hours.
• 30 days of annual leave plus additional special-leave days.
