## About the Role

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.

## 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
