We’re partnering with a leading enterprise organisation seeking a Senior Network & Firewall Engineer with strong, hands-on Fortinet Next-Generation Firewall experience.

What You'll Do

• Design, configure and implement Fortinet FortiGate firewall environments.
• Deliver complex enterprise firewall migrations and cutovers.
• Work across HA/clustered environments and multiple VDOMs.
• Manage Fortinet environments using FortiManager and ADOMs.
• Configure and troubleshoot static and dynamic routing.
• Develop detailed migration, implementation and rollback plans.
• Troubleshoot complex firewall, routing, NAT and VPN issues.

• Review and understand environments where documentation is limited or outdated.
• Produce clear technical documentation and implementation plans.

• Enterprise firewall migrations
• Static and dynamic routing
• BGP / OSPF or similar
• NAT, VPN and firewall policies
• Production and DR environments
• Complex network troubleshooting
