Network Security Engineer - Routing & Switching, Load Balancing, Proxy

The Role :

We're looking for a Network Security Engineer with strong Routing & Switching skills alongside Load Balancing and Proxy experience (e.g. Blue Coat, Zscaler). This is a hands-on engineering role covering project implementation, deployment, and troubleshooting.

What You'll Do :

- Design, configure, and troubleshoot routing protocols (BGP, OSPF) across enterprise networks

- Configure and manage switching infrastructure to support secure, reliable connectivity

- Implement and maintain firewall policies and rules to protect network traffic (firewall skills required, not looking for Data Centre-specific technologies)

- Deploy and manage load balancers (F5 or equivalent), configuring VIPs, health monitors, and traffic distribution

- Configure and optimise proxy/secure web gateway solutions (Blue Coat, Zscaler, or similar), including policy-based access control, SSL inspection, and URL filtering

- Produce clear design documentation (HLDs/LLDs) for network and security changes

- Support project delivery from design through to implementation and go-live

- Troubleshoot routing, switching, firewall, load balancing, and proxy issues as they arise

What You'll Need :

- Strong hands-on experience with routing and switching (BGP, OSPF) - CCNP or CCIE level

- Firewall configuration and troubleshooting experience

- Experience with load balancing technologies (F5 or equivalent)

- Proxy/SWG experience across a mix of platforms (Blue Coat, Zscaler, or similar)

- Proven project engineering and implementation experience, not just BAU support

- Strong troubleshooting skills across routing, switching, and security technologies

- Clear communicator, comfortable producing technical documentation and working across teams

Certifications :

- CCNP or CCIE (Routing & Switching) required

- Firewall vendor certifications desirable (e.g. Fortinet NSE, Palo Alto PCNSE, Check Point CCSA/CCSE)
