A company or organisation requires a complex network infrastructure and connectivity for employees to share data or resources easily and facilitate uninterrupted communication flows. A network engineer designs, implements and troubleshoots any problems associated with the network. They also help other employees and staff members to access this network, build secure protocols and maintain the network. In this article, we discuss the answers to 'what does a network engineer do', the work environment, qualifications, skills required and future career prospects of a network engineer.

What Does A Network Engineer Do?

To answer 'What does a network engineer do?', it is important to understand why their role is vital to an organisation. Companies and their employees can operate more effectively when they can share communication, data, files and relevant resources. To facilitate this, a secure network and internet connectivity are useful. Unfortunately, a network can be quite prone to cyber-attacks, which may cause loss or corruption of valuable data and files. Hence, network engineers establish robust security measures to prevent such thefts or occurrences.

Here are some common duties and responsibilities of a network engineer:

  • Create networking environments: Network engineers are responsible for creating and maintaining networking environments and capabilities. They design system configuration, direct system installation on the client's device and define associated protocols.

  • Innovation and optimisation: They continuously work towards making the existing environment and configurations sturdier. They also devise more effective and innovative solutions that may be useful in the future.

  • Enhance performance: Network engineers aim to enhance the current performance of the networking environment. They constantly audit performances, fix any related problems and keep the system updated.

  • Network security: They define essential network security protocols, create firewalls and administer policies. Network engineers also maintain access control.

  • Management and training: After attaining a certain level of experience and expertise, some network engineers may manage and train their subordinates.

Apart from the educational qualifications, a strong background or knowledge of mathematics and physics can be an asset. A network engineer usually displays in-depth knowledge and understanding of various aspects of a network and connections so that they can establish, manage, maintain and troubleshoot any problems associated with these complex setups. Here are some basic concepts that network engineers would know:

  • Network: A network exists whenever two or more devices get connected through a medium like cables, radio waves, infrared beams or telephone lines. A network consists of a few elements.

  • Server: A server is a primary device that stores and transmits data to other devices or computers within a network.

  • Client: This is the computer or device that receives the requested data from the server over a network.

  • Router: A router is a device that directs traffic between the Internet and computers or other devices in its proximity.

  • Switch: A switch acts as a mediator within a network that connects and pushes the information or data forward to the requesting device.

  • IP address: An IP address is a numerical string that identifies a device or a computer and its location so that the right computers can send and receive information from each other.

  • Network traffic: This is the data that is being transmitted between computers at a particular time. When many users are using their systems, network traffic is usually high.

There are different types of networks with which network engineers may work. Some of these are smaller in size and range, and they cover fewer devices, while others are larger and encompass a wider area with more systems and devices. The security and network protocols can vary according to the network. Some of these networks include home network, Local Area Network (LAN), Metropolitan Area Network, Wide Area Network (WAN), Global Area Network, voice over internet protocol, intranet and extranet.


Although certain employers prefer their network engineers to hold degrees, you can become a network engineer even without them. You may undergo targeted training or short, focused courses that apply to the field. The completion of such courses can lend the required knowledge and skills.
