Responsibilities

Design, build, and evolve high-availability data centre networks, including leaf–spine fabrics, switching, routing, firewalls, load balancers, segmentation, and inter-data-centre connectivity.
Engineer and operate scalable underlay and overlay networks using Ethernet, VLAN, MLAG/vPC, OSPF, BGP, VXLAN, and EVPN.
Personally operate mission-critical network services in-house, with direct responsibility for availability, capacity, performance, and reliability.
Perform hands-on troubleshooting across physical, switching, routing, security, and application-delivery layers, restoring services and driving permanent fixes.
Build and maintain automation using Network-as-Code practices to support provisioning, validation, compliance checks, testing, deployment, and drift-detection.
Use telemetry and observability data to proactively identify risks, optimise performance, and support future growth.
Explore and apply automation, AI, and AIOps techniques (e.g. anomaly detection, predictive insights, AI-assisted troubleshooting) to improve operational efficiency.
Work closely with cloud, compute,storage, cybersecurity, and application teams to deliver secure, reliable connectivity.
Evaluate new technologies and challenge vendor proposals, adopting solutions that can be effectively automated and operated in-house.
