This is a chance to join a large, mission‑critical transport and logistics organisation where the network genuinely matters. The infrastructure supports nationwide operations and is treated as a strategic asset, not an afterthought. The business is investing heavily in SD‑WAN and core network modernisation, and these roles sit right at the heart of that journey. You’ll be trusted to design, improve, and support a complex enterprise network, working with modern WAN technologies and solid Cisco foundations.

This is not a reactive support role. You’ll have influence, technical ownership, and the backing of a stable organisation that values long‑term thinking, engineering quality, and work–life balance. Add in a final salary pension and flexible hybrid working, and this is a rare combination of technical depth and stability.

• Act as a senior escalation point for complex routing, switching, and WAN issues.
• Support and improve Cisco‑based routing and switching estates.
• Deliver network upgrades, migrations, and improvement projects.
• Work closely with internal IT and business stakeholders to ensure performance and resilience.
• Produce and maintain high‑quality documentation and network designs.
• Contribute to both BAU operations and project‑led work.

• Strong enterprise networking background with Cisco routing and switching.
• Proven experience with SD‑WAN using one or more vendors, including Fortinet SD‑WAN, HPE Aruba Silver Peak, VMware Velocloud.
• Confident troubleshooting WAN, LAN, and routing issues in complex environments.
• Experience operating in large, business‑critical networks.
• Clear communicator with a pragmatic, senior engineering mindset.

• Exposure to F5 load balancing.
• Experience in regulated, transport, or critical national infrastructure environments.
