Frequently asked questions about Network Engineers


What is the difference between a Network Engineer and a Network Administrator?

The difference between a Network Engineer and a Network Administrator is their level of seniority and specific job responsibilities. For example, Network Engineers design and create computer network systems to reflect business needs. They also work on system updates to refine computer networks for their employer. In contrast, Network Administrators get involved after the creation of a computer system. They use their knowledge of information technology to monitor network efficiency and provide assistance to company employees.

Further, Network Engineers typically hold more senior positions when compared with Network Administrators because they require a few years of experience working as an Administrator before being able to qualify for an Engineer role. Network Engineers collaborate with Network Administrators to teach them about existing systems or upgrades. They also help Network Administrators address system issues and troubleshoot errors.


What are the daily duties of a Network Engineer?

On a typical day, a Network Administrator starts by checking their email and voicemail to respond to messages from upper management or lower-level company employees. Throughout the day, they meet with company Executives and other personnel to determine new networks or additional components necessary to refine company network systems. During downtime in their office, Network Engineers work on ongoing projects. They write instruction manuals for employees or code libraries for IT professionals so they can successfully navigate the company’s networking systems.


What qualities make a good Network Engineer?

A good Network Engineer has excellent verbal communication. These qualities enable them to speak with company Executives and other personnel to identify the best ways to structure a company’s computer networks. They also have superb written communication, allowing them to compose instruction manuals and employee training documents on how to use the system. They continuously look for ways to expand their skill sets and participate in certification programs for different coding languages or computer systems management techniques. 

Further, a good Network Engineer values constructive feedback from company Executives or employees and uses feedback to their advantage to develop even better computer networks.


Who does a Network Engineer report to?

A Network Engineer usually reports to the Chief Technology Officer (CTO) or the Chief Information Officer (CIO) within a corporation. These individuals are responsible for overseeing a company’s technology systems and how they uphold daily business operations. Network Engineers refer to the CTO or CIO to learn more about company technology needs or receive feedback about existing networks. In smaller corporations, Network Engineers may report directly to the Chief Executive Officer (CEO).
