Our Las Vegas headquarters is home to our national customer service, accounting, and technology teams, as well as our Network Operations Center (NOC), which provides Internet security services and 24/7 remote network monitoring.

• Install, configure, troubleshoot, and monitor Layer 2 and Layer 3 networks using routers and switches to meet client requirements and company standards.
• Use network discovery and show commands - including CDP/LLDP, MAC address tables, ARP tables, and Spanning Tree - to map topology and trace connectivity paths.
• Proactively monitor networks, open investigation tickets, research best practices, and document changes and technical reasoning.
• Work with upstream providers to provision Internet circuits for redundant BGP routing, filter routes, perform traffic engineering, and drive circuit or routing tickets through resolution.
• Configure and troubleshoot specialty hotspot gateways and high-density wireless networks supporting thousands of users, including the DHCP, DNS, and NAT services required for client Internet access.
• Plan and complete network and infrastructure maintenance during outage windows, coordinating with stakeholders to protect essential services and minimize downtime.
• Occasionally travel offsite to provide advanced technical support, rapid diagnostics, troubleshooting, and daily monitoring reports for client events in other Smart City facilities.

What You Bring

• High school diploma or equivalent
• 2-3 years of experience as a Network Administrator with a LAN/WAN focus, or equivalent experience.
• Working knowledge of Layer 1-3 networking, including Layer 2 configuration, Layer 3 interfaces, routing, switching, topology mapping, and connectivity troubleshooting.
• Experience with BGP, route filtering, traffic engineering, and upstream providers in support of reliable, redundant Internet connectivity.
• Familiarity with DHCP, DNS, and NAT and their role in providing client Internet access.
• Strong ownership and investigative skills with the ability to ask pertinent questions, evaluate evidence, research solutions, and document decisions.
• Industry-specific certifications such as CCNA, CWNA, MTA, MCSA, or comparable Cisco, Microsoft, or networking credentials.
• Ability to work with minimal supervision, collaborate across support tiers, and remain effective while troubleshooting time-sensitive client issues.
