Responsibilities
Monitor network health, troubleshoot connectivity/latency/port issues, and review logs and alerts
Configure switch ports, VLANs, trunks, and basic Layer 2 settings under change procedures
Assist with installing and labeling switches, wireless access points, optics, and cabling; perform basic cable testing and physical-layer troubleshooting
Maintain network documentation, including device inventory, assigned IP addresses, VLANs, switch-port records, uplinks, and diagrams.
Coordinate with OT engineers, system admins, vendors, and end users during troubleshooting

Basic knowledge of VLANs, access/trunk ports, and Ethernet switching
Comfort with basic troubleshooting tools (ping, traceroute, ARP, ipconfig/ifconfig, DNS lookups)
Basic Windows and Linux command-line familiarity
Strong documentation habits, clear communication skills, and the ability to read technical documentation and follow established procedures
Ability to troubleshoot in a structured, methodical way — gathering evidence rather than making random changes — and to escalate before making risky production changes
