Lead Catalyst Center–driven automation: design templates, SDA workflows, network assurance, SWIM, and closed-loop operations aligned to reliability/SLOs
Design identity-centric security with ISE: policy sets, authorization profiles, posture, PxGrid integrations, wired/wireless 802.1X/MAB, guest/BYOD, and scalable group policies
Engineer secure edge and campus perimeters: Cisco FTD/Firepower policy design, NAT, VPN, IDS/IPS, SSL decryption strategy, and high availability
Architect SD-WAN underlay/overlay: transport independence, application-aware routing, DIA/Cloud on-ramp, security integration, and multi-region scale
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

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
Deep expertise with Cisco ISE (policy, 802.1X, SGT/TrustSec) and Cisco FTD (Firepower) firewalls (threat, access control, NAT/VPN, high availability)
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
