A Network Infrastructure Engineer is responsible for designing, deploying, and securing the network of an organization. The individual performs site surveys and audits to ensure that the organization's network site has the proper specifications.
Network infrastructure entails using the software and hardware assets of a network that facilitates the communication of the organization's entire network, besides communications, network connectivity, management, and operations. It enables the interface between users, applications, services and the Internet and more.
The various components of network infrastructure include switching, routers, firewalls, servers, personnel, equipment, and infrastructure software, among others.
Engineers have to ensure further that their networks operate with minimal downtime. They also have to ensure that their organizations are compiling with network architecture policies and procedures.
Engineers have come up with approaches to reduce operational costs and improve their infrastructure efficiency and to ensure their organization's information security. Importantly, they have to work flexible hours.
