• Develop low-level designs, technical documentation, automation configurations, testing plans and implementation activities for the production network.
• Contribute to onboarding routers and switches across the Telco IP network, including large-scale Provider Edge solutions using Cisco, Juniper and Nokia technologies.
• Collaborate with internal customers, project teams, vendors and wider IP teams to clarify requirements, assess feasibility and finalise solutions through the review process.

• Strong experience designing and managing BNG, CGNAT, Telco Cloud Connect edge router, data-centre fabric and firewall solutions across on-premises and hybrid cloud environments.
• Practical understanding of network security, including IPSEC, MACsec, DDoS mitigation, micro-segmentation, zero-trust architectures, network hardening and BGP security, together with experience using automation frameworks such as Ansible, NSO and Netconf/YANG.
• A strategic, customer-focused and collaborative approach, with strong communication, coaching, mentoring, vendor management, problem-solving and influencing skills, and the ability to work under pressure, including late-night implementation and troubleshooting activities.
