Network Administrator
Keeps an organisation’s local and wide-area networks running day to day: switches, routers, wireless, IP addressing, user connectivity and monitoring.
What the job involves
A network administrator keeps an organisation's network usable every working day. The job covers configuring and monitoring switches, routers, firewalls and wireless access points, managing IP addressing and VLANs, fixing connectivity faults, and keeping documentation accurate enough for someone else to take over.
Where the work is
Ministries, district offices and public agencies, hospitals, universities and TVET schools, banks and insurers, telecom operators and internet service providers, and the ICT teams of NGOs and private companies.
How people get into it
Most people start with a diploma or degree in computer engineering, IT or telecommunications, then spend time in IT support or as a network technician before running a whole network. A certificate such as CompTIA Network+ or Cisco CCNA helps a CV stand out at that step.
