Network Security Engineer IV
About The Position
Responsible for the deployment, configuration, and operational support of enterprise firewall infrastructure. This role requires a strong understanding of enterprise networking fundamentals, including routing, switching, and end-to-end traffic flow, as well as LAN and WAN troubleshooting experience.
