This role provides broad exposure to enterprise networking technologies and an opportunity to continue developing technical expertise alongside an experienced engineering team.

Key Responsibilities

• Support day-to-day enterprise network operations and resolve network-related incidents and service requests.
• Configure, troubleshoot, and maintain enterprise switches, routers, wireless infrastructure, and related network technologies.
• Create and manage VLANs, trunk ports, switching configurations, and network segmentation.
• Perform firmware, software, and code upgrades across network infrastructure.
• Review running and saved configurations and troubleshoot configuration-related issues.
• Execute network changes, including verification, rollback, and change-management procedures.
• Troubleshoot routing, switching, connectivity, wireless, and firewall-related issues.
• Provide advanced escalation support for complex networking problems.
• Support enterprise data center, corporate, and multi-site network environments.
• Assist with monitoring, alerting, network performance, and infrastructure lifecycle activities.
• Coordinate with telecommunications carriers and technology vendors to troubleshoot circuit and infrastructure issues.
• Participate in scheduled maintenance windows and an on-call rotation as required.
• Continue developing expertise across networking technologies, security platforms, wireless infrastructure, and network automation.

Required Qualifications

• Approximately 4-7 years of hands-on network engineering experience.
• Strong understanding of networking fundamentals, including:
  • TCP/IP and the OSI model
  • IP addressing and subnetting
  • Routing and switching
  • VLANs and trunking
  • Spanning Tree
  • DHCP and DNS
• Hands-on experience configuring enterprise switches through CLI.
• Experience creating VLANs, configuring trunk ports, and implementing network changes.
• Experience performing firmware or software upgrades on network equipment.
• Ability to read, review, and troubleshoot network configurations.
• Experience troubleshooting network issues in a production environment.
• Working knowledge of firewall policies and network security fundamentals.
• Strong problem-solving skills with the ability to work independently.
• Self-motivated, curious, and interested in learning new technologies.

Preferred Qualifications

• Experience with Aruba switching and/or wireless technologies.
• Experience with Cisco networking technologies.
• Experience with Palo Alto firewalls.
• Experience with Juniper/Junos networking platforms.
• Exposure to SD-WAN technologies such as VeloCloud, Viptela, Silver Peak, or similar.
• Experience supporting large, distributed, or multi-site network environments.
• Enterprise wireless experience, including 802.11 and 802.1X.
• Data center networking experience.
• Familiarity with packet capture and network analysis tools.
• Exposure to routing protocols such as OSPF and BGP.
