Job description

We're recruiting for a Senior Network Security Engineer to join a specialist networking and security business that is continuing to grow following a strong period of project wins.

This is a good opportunity for someone who wants to stay technically hands‑on while taking more ownership across security design, implementation and project delivery.

The role sits at the intersection of networking and security, with responsibility for taking customer solutions from requirements and design through implementation, testing and ongoing technical ownership.

The Role

You’ll be involved in:

• Designing and implementing network security solutions
• Leading technical projects from requirements through delivery
• Producing security designs and implementation plans
• Firewall deployments, migrations and upgrades
• SD‑WAN, SASE and ZTNA projects
• VPN and secure remote‑access solutions
• Security audits and technical health checks
• Supporting and improving existing customer environments
• Acting as a senior technical escalation point
• Working directly with customers and technical stakeholders
• Mentoring and supporting developing engineers

Technology Environment

Experience across some of the following would be particularly relevant:

• Fortinet / FortiGate
• SD‑WAN
• SASE
• ZTNA
• Firewalls / UTM
• VPN
• SAML / MFA
• SIEM
• SOAR
• XDR
• LAN / WAN
• Routing and switching
• Network security architecture

You do not need to tick every technology listed.

What I’m Looking For:

I’d be keen to speak with people coming from backgrounds such as:

• Senior Network Security Engineer
• Network Security Consultant
• Network & Security Engineer
• Infrastructure & Security Engineer
• Firewall / Security Engineer
• Senior Network Engineer with strong security exposure

The strongest profiles will combine solid networking fundamentals with genuine security design and implementation experience.

Fortinet experience is particularly useful, especially around FortiGate, SD‑WAN, SASE or ZTNA.

Experience producing technical designs, leading implementations and taking ownership of customer projects will be equally important.

The Opportunity

• £50,000 to £67,500 basic salary
• Strong pipeline of project work
• Mix of design, implementation and technical ownership
• Broad networking and security exposure
• Opportunity to develop towards architecture
• Continued technical and certification development

If you’re currently spending too much time in BAU and want to get back into proper engineering, design and project delivery, I’d be interested in speaking.
