Working in conjunction with a team of Network Architects, Network Engineer and Systems Infrastructure Engineer, you shall help plan and execute the tasks required to separate Entanet’s network from CityFibre, optimise and decommission legacy as well as build new capabilities that the business requires.

You will also be key to supporting the network architects as we implement new ISP core OSS systems, and replace the existing network for a new one.

• Manage BGP peering, IS-IS, VRFs, VLANs, MPLS and IP transit and peering.

• Maintain the NetBox IPAM and NMS and keep network records accurate.

• Collaborate with the network architects with HLD/LLDs.

• Collaborate with the system infrastructure engineer for any network related systems and networking requirements.

• Support circuit provisioning and carrier ENNI handoffs.

• Support colocation and backhaul rationalisation and circuit migrations from EAD LA (unbundled exchanges) to carrier Ethernet.

• Act as the escalation point from the NOC team for complex network faults and changes.

• Participate in an on-call rotation to maintain network availability.

• Design and implement network automation tooling/scripting, including YANG/Netconf, with Ansible playbooks or other API/SDN capabilities.

• Leverage AI-assisted agents and copilots (e.g. Claude, GitHub Copilot) to accelerate implementation and diagnostics, automate repetitive change tasks and reduce MTTR.

• Depending on experience, supporting maintain ISP OSS systems, including physical server infrastructure, virtualisation, operating systems and applications.

• Hands-on experience configuring and troubleshooting carrier or ISP networks in a BAU environment.

• Strong working knowledge of BGP, IS-IS, MPLS, VPLS, SR-MPLS, EVPN and other carrier architecture.

• Experience of circuit provisioning, carrier handoffs and change management at scale.

• Working with Cisco ASR, Nexus and Catalyst products.

• Strong fault diagnosis and problem-solving under pressure.

• Methodical approach to change management and documentation.

• Able to prioritise across continuous BAU change and incident activity.

• Willing to adopt AI copilots to speed up diagnostics and routine change.

Desirable Requirements

• Experience supporting colocation and backhaul environments.

• Exposure to EAD-to-carrier-Ethernet migrations.

• Previous experience in a separation or migration programme.

Qualifications

• Computer Networking or Computer Science degree.

• Relevant networking certification (e.g. CCNA/CCNP, JNCIA/JNCIP, or equivalent), or equivalent experience.
