Network engineers design, build and implement networks on behalf of companies, non-profits, and other organizations. In addition to this, network engineering involves maintaining the network and resolving or troubleshooting any issues which may arise.

The ultimate goal of a network engineer is to provide constant access to a secure, reliable network that allows users to maximize their performance.

Of course, computer networks vary depending on the needs of users. A multinational conglomerate may have a more advanced network than a small to mid-size company, for example. This variation ensures network engineers can specialize in certain areas, if they choose to, and gain experience across the industry.
