This is a hands-on technical leadership position for someone who can combine deep network engineering expertise with a strong focus on automation, observability and operational excellence.

The role

You’ll lead the day-to-day operation and continuous improvement of network infrastructure across datacentre, WAN and campus environments.

Alongside providing technical leadership to the network function, you’ll drive a more automated and proactive approach to network operations — reducing manual intervention, improving observability and ensuring the environment remains highly available, resilient and secure.

Key responsibilities

🔴 Lead the operational performance, stability and availability of the network environment

🔴 Improve network monitoring, telemetry, alerting and observability

🔴 Develop operational tooling, runbooks and incident response processes

🔴 Work closely with Network Security and Infrastructure Engineering teams

🔴 Support network architecture, upgrades, capacity planning and performance optimisation

🔴 Identify recurring issues and drive long-term technical improvements

What we’re looking for

🔴 Strong hands-on network engineering experience within enterprise or large-scale environments

🔴 Experience across datacentre, WAN and campus networking

🔴 Strong Cisco or Arista experience

🔴 Excellent understanding of L2/L3 networking, BGP and EVPN-VXLAN

🔴 Experience with network security infrastructure including firewalls, load balancers and proxies

🔴 Experience with Python, Ansible or similar automation tooling

🔴 Understanding of Infrastructure as Code and CI/CD

🔴 Experience with network observability and monitoring

🔴 Strong incident management and troubleshooting capability

🔴 Previous experience leading engineers, projects or a technical function

What’s on offer

🔴 Highly competitive salary + discretionary annual bonus
