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 — FortiGate, FortiManager, FortiAnalyzer, 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.

WHAT YOU'LL BE DOING

• 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 FortiGate, FortiManager, FortiAnalyzer, 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 LogicMonitor 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

TECH STACK

• FortiGate | FortiManager | FortiAnalyzer | FortiSD-WAN | FortiSASE

• VPN | LogicMonitor / PRTG

• Meraki | Cisco | HPE Aruba / Silverpeak SD-WAN

WHAT WE'RE LOOKING FOR

• Deep Fortinet expertise — FortiGate, FortiManager, FortiAnalyzer, 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

• LogicMonitor 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

THE PACKAGE

• £55,000 base salary

• Hybrid: Wednesday in the office, rest from home

• Staggered shifts: 7am–5:30pm across a team of six

• Potential on-call element

WHY THIS ROLE STANDS OUT

• 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
