Network Engineer

In a nutshell, network engineers are responsible for building networks. The job is less about everyday network maintenance (which is typically handled by network administrators) than it is about the actual design and configuration of the network (which is an ongoing process, not a one-and-done).

Networks can be large or small. The biggest example is the Internet—but if devices are connected to another network, they can share information even if they have no Internet access. This is what makes networks so useful to companies and organizations, especially ones where employees work collaboratively.

Ultimately, network engineers must be flexible and responsive to the needs of their company.
