Configure and troubleshoot static routing and OSPF.

Configure VLANs, trunking, STP, inter-VLAN routing, and network segmentation.

Configure firewall policies, ACLs, NAT/PAT, and secure network access.

Troubleshoot network issues using Ping, Traceroute, ARP, DNS, DHCP, Wireshark, and other diagnostic tools.

Configure and maintain basic network services including DHCP, DNS, and NTP.

Monitor network performance, availability, bandwidth utilization, and connectivity.

Support communication between servers, workstations, sensors, and other network-connected systems.

Integrate networking infrastructure with defence electronics, surveillance systems, sensors, command-and-control systems, and mission-critical platforms.

Provide technical support and troubleshooting at customer/field locations as required.

Participate in system integration, testing, commissioning, and deployment activities.

Coordinate with hardware, RF, embedded, software, and system engineering teams.

Maintain network diagrams, IP address plans, configuration records, and technical documentation.
