Clear Route is looking for a Network Security Engineer to take ownership of firewall policy management and network security operations across our client estate, with Algo Sec at the centre of the toolset.

Alongside the technical delivery, you'll be a trusted voice with both technical and executive stakeholders identifying where security posture, operational resilience, and business need are in tension, and helping clients navigate that trade-off with clear, well-reasoned recommendations.
