Network engineers keep data flowing — designing, configuring and troubleshooting the routers, switches, firewalls and wireless systems that connect people and systems.
Network Design
Plan and build LAN, WAN and data centre networks from scratch using Cisco routing and switching.
Firewall & Security
Configure Cisco ASA and Palo Alto firewalls, VPNs and access control lists to protect the perimeter.
Troubleshooting
Diagnose and fix connectivity issues fast — using packet captures, ping, traceroute and SNMP monitoring.
Wireless & Cloud
Deploy and manage Wi-Fi infrastructure and integrate on-premise networks with AWS or Azure cloud.
