Network Engineer III

About the role

We're looking for a Network Engineer III to join a security remediation team focused on patching and upgrading network devices. This is a great fit for a strong network engineer who doesn't necessarily come from a security background but is comfortable navigating devices, performing upgrades, and working independently.

• Install, configure, and upgrade Cisco routers and switches; execute device changes, upgrades, and replacements
• Support vulnerability management and exposure management efforts

• Create and execute CLI commands and manage IPv4 configurations
• Use command line and traceroute to troubleshoot and validate device access
• Apply engineered Layer 3/Layer 4 routing architecture across enterprise routing and switching environments
• Participate in maintenance windows as needed (occasional, not a regular occurrence)
• Work directly with customers and stakeholders throughout the engagement
