L3 Network Engineer

Job Title : L3 Network Engineer
Location : Dallas, TX 75235

Duration : 12 months (with possible extension)

Job Description

We're looking for engineers with hands-on operational experience in large Cisco enterprise environments who can contribute with minimal ramp-up time.

Our current environment includes:

• Cisco Software-Defined Access (SDA)
• Cisco Catalyst Center (DNA Center)
• Cisco Identity Services Engine (ISE)
• Cisco Catalyst 9800 Wireless Controllers
• Cisco Catalyst 9130/916x Access Points
• High-density enterprise and healthcare wireless
• Cisco Nexus data center technologies, including VXLAN/EVPN and Nexus Dashboard (NDFC)
• Cisco routing and switching
• Cisco Secure Firewall technologies
• Azure connectivity (ExpressRoute) and hybrid networking
• ServiceNow change, incident, and operational workflows

From an experience perspective, we're looking for candidates who can demonstrate real-world operational ownership—not just exposure. Strong candidates should be comfortable discussing topics such as:

• Troubleshooting Cisco SDA fabrics and Catalyst Center
• Cisco ISE authentication, authorization, profiling, and endpoint onboarding
• Enterprise wireless troubleshooting, RF optimization, roaming, and client performance
• Routing protocols including BGP, OSPF, and EIGRP
• Data center networking using VXLAN/EVPN
• Large-scale Cisco switching and routing
• Incident response and root cause analysis in a production environment
• Working in a 24x7 operational support model with on-call responsibilities

Candidates whose experience is primarily limited to traditional routing and switching, data center deployments, or configuration work—without hands-on experience supporting SDA, Catalyst Center, ISE, and enterprise wireless—typically are not the right fit for this role.

Healthcare experience is certainly a plus, but it isn't required. What's most important is experience supporting large, always-on Cisco enterprise environments where uptime, operational excellence, and troubleshooting are critical.
