L1 Network Operation Support Engineer

You will be responsible for configuring and troubleshooting network devices, including VLAN, STP, VTP, and EtherChannel. You will monitor network performance, respond to alerts and incidents using network monitoring and ticketing tools, and troubleshoot LAN/WAN, Wi-Fi, VPN, and GPON network (OLT and ONT) issues. In case of unresolved issues, you will escalate them to senior teams or vendors. Your tasks will also include documenting incidents, troubleshooting steps, resolutions, and updating standard operating procedures (SOPs). Additionally, you will manage RMA processes for hardware issues diagnosed during support, participate in network design discussions and capacity planning activities, and travel to customer sites as required to resolve support requests. To excel in this role, you should have hands-on experience with switching protocols such as VLAN, STP, VTP, and EtherChannel. A strong understanding of routing protocols, IP addressing, and subnetting is essential. Experience with GPON network devices, including basic configuration and troubleshooting of OLT and ONT, is required. You should possess good knowledge of TCP/IP, DNS, DHCP, NAT, as well as familiarity with network security concepts like ACLs, VPNs, and firewalls. Proficiency with network monitoring tools and ticketing systems is expected, and experience with packet analyzers like Wireshark would be a plus. The ability to work in rotational shifts, especially in a NOC role, is also necessary for this position.,
