Senior Network Support Engineer

Senior Network Support Engineer — Fortinet technical lead on a skilled, established team

£55,000 | Hybrid | Wednesday office only

Our client has a skilled team of six network support engineers and they're looking for a technical lead to sit at the top of the escalation chain. This is a 3rd and 4th line role with a genuinely proactive bent — you're not just resolving tickets, you're identifying patterns, driving BAU improvement projects, and stopping problems before they happen.

The stack is 95% Fortinet — Forti Gate, Forti Manager, Forti Analyzer, FortiSD-WAN, and FortiSASE. If you've spent your career going deep on Fortinet and you want a support-focused role with real technical authority and minimal commute (just Wednesdays in the office), this is worth a serious look.

• Own 3rd and 4th line escalations across the Fortinet estate — the senior technical authority on the team
• Drive proactive support — identify recurring issues, run BAU improvement projects, and reduce ticket volume before it happens
• Manage and support Forti Gate, Forti Manager, Forti Analyzer, FortiSD-WAN, and FortiSASE environments
• Support SD-WAN deployments and ongoing management across the customer base
• VPN configuration, management, and troubleshooting across the estate
• Use Logic Monitor or PRTG for network monitoring and performance visibility
• Support the project team when required — dip into project delivery alongside BAU
• Contribute to a staggered shift pattern — 7am–5:30pm across a team of six

• Deep Fortinet expertise — Forti Gate, Forti Manager, Forti Analyzer, and SD-WAN hands-on experience
• SD-WAN experience essential — Fortinet SD-WAN preferred, Meraki or HPE Aruba Silverpeak also considered
• Consultant or senior engineer background happy to step into a senior support-focused role
• Proactive mindset — you look for root causes and fix them, not just close the ticket
• VPN configuration and troubleshooting experience across the Fortinet stack
• Logic Monitor or PRTG monitoring platform experience beneficial
• Fortinet NSE5 certification preferred — other NSE certs considered
• Comfortable in a staggered shift environment — 7am–5:30pm rotated across the team

• Hybrid:
  Wednesday in the office, rest from home
• Staggered shifts: 7am–5:30pm across a team of six

• Almost entirely Fortinet — if that's your world, this role lets you live in it
• Proactive support focus — you're improving the network, not just firefighting
• Just one day a week in the office — genuinely flexible working arrangement
• Skilled, established team — you're joining peers, not carrying juniors
• Project team exposure — variety without it being a pure delivery role
• Senior technical authority — real escalation ownership, not another mid-level support seat
