• Expert routing at scale : BGP (policy, route reflectors, communities), OSPF, EIGRP, ECMP, redistribution strategies, route filtering, summarization, and IPv6 planning.
• Drive modernization roadmaps : brownfield to SDA migration, hierarchical campus design, QoS, multicast, wireless controller (Catalyst 9800) alignment, and resiliency patterns.
• Deliver hands on build and escalation leadership : lab validation, pilot, phased rollout, cutover plans, MOPs, change windows, and root cause analysis for P1 / P2 incidents.
• Mentor and uplift engineering teams : design reviews, standards, runbooks, and enablement sessions for operations and field engineers.
• Stakeholder leadership : collaborate with security, EUC, cloud, and application teams; translate business outcomes into technical architectures and measurable milestones.
• Documentation & governance : HLD / LLD, as builts, standards, security exceptions, and compliance artifacts; contribute to reference architectures and reusable templates.

Required Qualifications (Must Have)

• Active CCIE (any track; Enterprise Infrastructure and / or Security strongly preferred).
• 10+ years enterprise networking experience, including 3-5+ years leading SD Access architecture and deployment across multiple sites.
• Proven, exceptional hands on skills with Cisco routing / switching and Catalyst Center (formerly Cisco DNA Center) for SDA automation and assurance.

• Strong experience with Cisco SD WAN (design, policy / templating, security integration, operationalization).
• Expert level knowledge of BGP, EIGRP, OSPF, redistribution, and route policy design for large enterprises.
• Demonstrated success leading complex, multi phase migrations and mentoring senior engineers.
