• You configure and operate our Fortinet/FortiGate and Cisco Meraki infrastructure, including firewalls, routing, switching, VPN, and WLAN.
• You systematically analyze network and performance problems, resolve incidents, and support complex malfunctions and root-cause analyses.
• You plan and implement secure connections between on-premises and cloud infrastructures and actively help shape our future hybrid network architecture.
• You work closely with our system, cloud, security, and application teams and ensure that new systems and services are cleanly integrated into our network and security architecture.
• You implement group, security, and architecture specifications in a practical manner and, together with the relevant teams, further develop standards for network design, operation, and documentation.
• You automate and standardize recurring network tasks where sensible and ensure up-to-date and traceable technical documentation.
• You support the further development of our internet-facing infrastructure, for example in the area of application gateway, reverse proxy, and Web Application Firewall (WAF).

Qualifications

What you bring with you

• Completed training or comparable qualification in the field of computer science, network, or system technology.
• Several years of practical experience in the design and operation of enterprise networks, ideally in environments with high requirements for availability and security.
