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.
