what is a network engineer?

As a network engineer, you maintain the connectivity of networks in organisations. You ensure data, calls, videos, voice, and wireless network services are always available. The role involves formulating, executing and implementing entire computer networks in a company. You ensure all the network systems are functioning correctly. You also provide quality network infrastructure, performance and security to end users.

Aside from installing and implementing network systems, you monitor the existing networks. You assess any network problems and devise solutions to improve connectivity. You also perform routine maintenance on critical systems. That involves evaluating performance and diagnosing and repairing network issues. Regular maintenance enhances network security for end users.

Successful network engineers rely on their technical skills to configure and maintain network architectures, including cloud computing, programming and cybersecurity. There are numerous specialised fields to explore in network engineering. For instance, you can become a network security specialist or a network architect. You also require soft skills —like analytical and problem-solving abilities— to diagnose and troubleshoot issues in the computer networks. A meticulous eye for detail is also valuable in the role.
