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

• Manage Fortinet environments using FortiManager and ADOMs.

• BGP / OSPF or similar
• NAT, VPN and firewall policies
• Production and DR environments
