Key responsibilities will include designing and administering FortiGate firewalls, FortiManager, FortiAnalyzer and associated Fortinet technologies; developing and maintaining firewall policies, VPNs, routing, switching and network security controls; and monitoring infrastructure to identify risks, capacity concerns and performance issues. You will lead the investigation and resolution of complex faults, provide technical escalation support, and oversee changes through appropriate testing, documentation and change-control processes.

Familiarity with network monitoring, vulnerability management, incident response and IT service management processes would be advantageous. Relevant Fortinet certification, such as NSE 4 or above, and additional networking qualifications including CCNA or CCNP are desirable. You will need excellent analytical and communication skills, a methodical approach to problem-solving, and the ability to manage priorities effectively while delivering reliable, secure solutions.
