Network Team Lead

Network Team Lead - Hybrid - £150,000 base - London

I'm supporting a leading quantitative technology firm that's looking to appoint a Network Team Lead to take ownership of the performance, reliability and operational maturity of its network environment.

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
• Provide technical leadership across network operations and incident response
• Lead the investigation and resolution of critical network incidents
• Drive automation using Python, Ansible and Infrastructure as Code
• 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
• 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

This is an excellent opportunity for a senior Network Engineer or existing Network Lead who wants to take ownership of a sophisticated network environment while helping shape the way network engineering is delivered through automation, observability and modern infrastructure practices.
