Job description

Position Summary

The Sr. Network Engineer possesses expert-level knowledge in the design, implementation, and troubleshooting of enterprise networking infrastructure across LAN, WAN, and Software-Defined Networking (SDN) domains. Core areas of expertise span enterprise campus, branch routing and switching, SD-WAN, SD-Access, SD-Branch, and next-generation network security integration. The Sr. Network Engineer operates in a professional services capacity delivering complex multi-site and multi-domain network solutions to enterprise customers across a variety of vendor platforms, with Cisco as the primary technology track. The Sr. Network Engineer shall support, mentor, and enable junior engineers while performing high-level design and configuration tasks with limited or no supervision.

Primary Position Tasks

• Design, implement, and support complex enterprise LAN and WAN solutions spanning traditional routed/switched infrastructure and modern Software-Defined Networking architectures across multiple vendor platforms.
• Lead SD-WAN deployments including controller/orchestrator onboarding, zero-touch provisioning (ZTP), policy development, traffic segmentation, and QoS configuration (e.g., Cisco Catalyst SD-WAN, Meraki, Palo Alto Prisma, Juniper Session Smart).
• Design and deploy SD-Access or equivalent campus fabric solutions including policy-based segmentation, network access control integration, and intent-based automation (e.g., Cisco SDA with Catalyst Center and ISE).
• Execute WAN circuit migrations and cutovers - including MPLS-to-SD-WAN transitions - and campus LAN modernization projects with minimal customer impact.
• Design and implement SD-Branch solutions that converge WAN connectivity, LAN switching, security, and wireless functions at the branch edge.
• Support, troubleshoot, install, and configure complex enterprise routing, switching, and SDN infrastructure in Cisco-primary and multi-vendor environments.
• Assess, document, and report on enterprise networks to drive LAN/WAN modernization, SDN adoption, and infrastructure refresh initiatives.
• Maintain industry certifications as required to retain strategic OEM partnerships.
• Review and approve new opportunity statements of work (SOWs) and level of effort (LOE) estimates related to the growth of our Modern Infrastructure practice.
• Collaborate closely with design engineering resources when scoping larger LAN, WAN, and SDN-related projects and programs.
• Articulate modern network service capabilities and deployment methodologies - including SDN, cloud networking, and automation in internal and customer-facing capacities.
• Assist pre-sales with customer engagements, technical presentations, and solution demonstrations when applicable.
• Assist in developing, improving, and automating delivery methodologies.
• Other business duties as assigned.

Minimum Education/Certification/Experience Requirements

• 7+ years of related experience in a field or professional services role, with significant focus on enterprise LAN/WAN design and deployment.
• Current professional-level networking certification required (Cisco CCNP Enterprise preferred; JNCIP, ACCP, or NSE7 also considered); CCIE or equivalent expert-level certification strongly preferred. Additional OEM certifications valued (PCNSE, JNCIP, NSE7, ACCP, etc.).
• Deep hands-on expertise with enterprise routing and switching platforms across one or more major vendors (e.g., Cisco Catalyst/ASR/ISR, Juniper EX/MX, Aruba CX, HPE).
• Demonstrated expertise in enterprise WAN design and implementation, including MPLS, DIA, broadband aggregation, and multi-WAN failover architectures. MPLS VPN (L3VPN/L2VPN) and carrier interconnect experience preferred.
• Strong proficiency in enterprise routing protocols: BGP (iBGP/eBGP, route policy, communities), OSPF, and EIGRP across multi-site environments.
• Solid foundation in enterprise LAN technologies: VLANs, STP variants (RSTP/MST), LACP, chassis stacking/virtualization, and campus network design.
• Experience with WAN QoS design and implementation, including traffic classification, marking, queuing, and shaping policies.
• Experience with enterprise network security technologies, including next-generation firewalls (e.g., Cisco Firepower, Palo Alto, Fortinet).
• Hands-on experience with at least one SDN platform spanning WAN, campus LAN, or branch domains is required; deeper, hands-on deployment experience in the following areas is preferred:
  • Experience with centralized/cloud network management and intent-based automation/cloud-managed platforms (e.g., Cisco Catalyst Center/DNA Center/Meraki, Juniper Mist/Marvis, Aruba Central) for unified LAN/WAN/wireless visibility and control preferred.
  • Experience with WAN observability and synthetic monitoring tools (e.g., Cisco ThousandEyes, IPSLA, NetFlow/sFlow analytics) for path visibility and SLA validation preferred.
