Qualifications

• CCIE Enterprise Infrastructure certification is mandatory.
• Expert-level BGP design, policy, traffic engineering and multi-carrier connectivity.
• Hands-on Cisco routing and switching in enterprise environments.
• Strong SD-WAN experience, especially Cisco Viptela.
• Solid understanding of OSPF, MPLS, VRFs, QoS and high-availability design.
• Experience delivering complex network migrations and transformation programs.
• Experience integrating enterprise networks with Azure/hybrid-cloud environments.
• Advanced troubleshooting using packet captures, routing diagnostics and telemetry tools.

Responsabilités

• Design, build, test and implement Internet Gateway migration solutions.
• Configure and troubleshoot complex routing environments (BGP, OSPF, MPLS, VRFs).
• Troubleshoot across Internet edge, SD‑WAN, WAN, LAN, cloud, security and carrier connectivity.
• Develop and execute migration plans, runbooks, cutovers and validation tests.
• Analyze dependencies across routing, security, DNS, DDI, remote access and cloud connectivity.
• Resolve migration blockers across network and security domains.
• Create and review low-level designs, implementation procedures and documentation.
• Collaborate with Network Architects to translate designs into deployable solutions.
• Lead major implementation events, service transitions and high-risk changes.
• Drive engineering best practices and operational readiness.
