Why This Role Stands Out

This on-site Network Administrator role offers a fantastic opportunity to deepen your expertise supporting a robust enterprise Cisco network, with a focus on hands-on troubleshooting and maintenance. You'll thrive here if you possess strong Cisco routing, switching, and wireless skills and enjoy taking ownership of critical network operations within a collaborative team environment.

Assist with network documentation and configuration management
Work closely with infrastructure and security teams to resolve issues
Participate in scheduled maintenance and after-hours support as needed

Required Skills
4+ years of enterprise network administration experience
Strong Cisco switching experience
Strong Cisco routing experience
Strong Cisco wireless experience
Excellent troubleshooting skills
Experience supporting production enterprise environments
Ability to work independently with minimal supervision
