• Maintain accurate documentation across incidents, changes, and configurations

• Contribute to continuous improvement across monitoring, tooling, and processes

Required Experience

• Experience within a Network Operations Centre or large-scale network environment

• Strong understanding of core networking concepts (e.g. BGP, MPLS, backbone networks)

• Exposure to optical networking technologies (e.g. DWDM, transport networks, fibre infrastructure)

• Hands-on experience with vendors such as Cisco, Juniper, or optical platforms

• Experience using monitoring and ticketing systems in an operations environment

• Ability to troubleshoot across multiple layers of the network stack

• Strong communication and documentation skills

Nice to Have
