What are the roles of a network engineer?

Overview

Network engineering is a profession in technology that is concerned with network planning and design, as well as technical specifications on how to run a network.

A network engineer is an individual who possesses the necessary skills to design computer networks within an organization or between two or more organizations. In addition, a network engineer makes plans regarding network specifications and needs.

Roles of a network engineer

1. Design: A network engineer has the responsibility of designing or re-designing a network based on organizational needs and environment.

2. Planning: A network engineer is responsible for making plans, in terms of both infrastructural and user access needs, for new and re-designed networks.

3. Implementation: A network engineer leads their network team members in the implementation of designed networks.

4. Documentation: A network engineer is responsible for documenting a designed network and interpreting network design diagrams.

5. Network management: Network engineers ensure network optimization by maximizing network performance through monitoring, troubleshooting, and defining user access.

6. Security: Network engineers provide adequate security for a network. This can be done through enacting policies, defining user access to the network, engaging IT security policies through firewall environment implementation, etc.

7. Configuration: A network engineer has knowledge of network equipment configuration, such as routers, switches, gateways, and hosted voice-over-internet protocol (VoIP) services.

8. Upgrade: A network engineer is responsible for designing and implementing new solutions during downtime, as well as upgrading network software to the latest versions to avoid breaches.

9. Network infrastructure: A network engineer specifies the best network infrastructure and equipment for any network. This is very important, as it can affect the performance of a network.

10. Team player: Network engineers are team players. They collaborate with other network engineers and workers to ensure the smooth running of networks.
