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
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.

WHAT WE'RE LOOKING FOR

- 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

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
