Network engineer

A network engineer is a technology professional who is highly skilled in maintaining the connectivity of networks in terms of data, voice, calls, videos and wireless network services. Sometimes referred to as network architects, network engineers are accountable for formulating, implementing and executing the whole computer networks of an organization.

The ideal role of a network engineer is to make sure all the systems are functioning properly as intended. The fundamental goal of a network engineer is to provide maximum network infrastructure, security and performance to the end users. Depending on an organization’s requirement or network complexity, the organization will sometimes have global network engineers across countries who take care of technological advancements throughout the firm.
This proves cost-effective for the organization while also meeting needs for both user and business.
