Job Description

• We are hiring for an L4 Network Architect/Engineer to lead design and delivery of multi site Cisco Software Defined Access (SD Access) solutions at scale.
• Contribute to and implement architecture direction, drive complex deployments across distributed campuses, and mentor engineers while partnering closely with security and operations.
• The ideal candidate holds an active CCIE and demonstrates deep, hands on expertise across Cisco routing/switching, Cisco Catalyst Center (formerly Cisco DNA Center), Cisco ISE, Cisco FTD firewalls, and Cisco SD WAN, with expert level command of BGP, EIGRP, OSPF, and related enterprise routing protocols.

• Own end to end SD Access architecture for large, multi site enterprises: fabric design (control/edge/border), transit options, segmentation (SGTs/TrustSec), identity policy, and integration with WAN and data center.
• 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.

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.

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.

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).
