Ict Network Administrator

An ICT Network Administrator is responsible for the reliable operation, security, and performance of an organization's computer networks. This role encompasses designing, implementing, and maintaining network infrastructure, including routers, switches, firewalls, and wireless systems. The administrator monitors network traffic, troubleshoots connectivity issues, and optimizes performance to support business-critical applications. They manage IP addressing, DNS, DHCP, VPNs, and network access controls, ensuring secure and efficient data flow. Collaboration with IT teams, vendors, and end-users is essential to resolve incidents, plan upgrades, and enforce security policies. Seniority levels range from Junior (focused on routine maintenance and support) to Mid (handling complex configurations and projects) to Senior (designing architectures, leading teams, and strategic planning). The role is well-suited for hybrid or remote work, though on-site presence may be required for hardware maintenance. Salary drivers include certifications (CCNA, CompTIA Network+), expertise in specific vendors (Cisco, Juniper, Palo Alto), and industry sector (finance, telecom, healthcare). Common stack signals include Cisco IOS, Juniper JunOS, Wireshark, SolarWinds, and cloud networking (AWS, Azure). The administrator must stay current with evolving technologies like SD-WAN, network automation, and zero-trust security models.
