Job description

📍 London - 4 days a week in office (1 day flexible)

Here at Burns Sheehan, we’re working with a premium London-based workspace provider with a large multi-site estate and a major technology programme running across their buildings and cloud platform.

They’re looking for a Senior Network Engineer to take full solo-ownership of their network estate, covering over 60+ buildings across London (and growing). This is a hands-on senior role and will suit someone who wants genuine ownership in a complex, constantly changing environment.

The role is 80% project-based, focused on network architecture, delivery, and security improvements, with the remaining 20% covering ongoing network management and optimisation.

What You’ll Be Doing:

• Owning the full Cisco Meraki estate across 60+ London sites (end-to-end responsibility)
• Designing and implementing improvements across a software-defined network using internet connectivity
• Connecting buildings securely into a Microsoft Azure platform (Azure networking focus is essential)
• Leading technical delivery across performance optimisation, resilience, and design upgrades
• Implementing cyber security requirements, working closely with internal security teams
• Acting as the technical escalation point and liaising with external vendors / service providers
• Producing and maintaining network documentation, standards, and diagrams

What They’re Looking For:

• Multi-site Experience with experience owning and operating networks across the estate.
• Hands-on expertise with Cisco Meraki (design, deployment, troubleshooting)
• Azure, ideally Azure networking experience (VNets, NSGs, VPN Gateway, Firewall, Virtual WAN)
• Deep knowledge of networking fundamentals: IP, routing, segmentation, VPNs / SD-WAN
• A security-first mindset (comfortable designing solutions that meet modern cyber requirements)
• Confident working independently as the primary technical owner in this area

If you’re interested in a role where you’ll genuinely own a complex multi-site network, lead major projects, and work closely with cyber security on modern access patterns (beyond point-to-point VPNs), drop me a message and I’ll share more.
