Network engineers are the technical experts responsible for setting up computer networks, maintaining them, and offering technical support to users where necessary. Ever heard of Wi-Fi, local area networks (LANs), wide area networks (WANs) or global area networks (GANs)? Well, these marvellous things allow us to communicate, exchange information and connect to the internet – and they’re looked after by network engineers.
Network engineers deal with both hardware and software. On the hardware side of things, they perform hands-on installation and maintenance tasks on network components such as routers, switches and cables. On the software side of things, network engineers monitor network activity and configure network systems using complex computer software. They constantly maintain and improve network security by setting up firewalls, and they’re also responsible for troubleshooting problems as and when they arise.
Some of the key responsibilities of a network engineer include:
- Troubleshooting network problems to maximize network performance
- Administering firewalls and maintaining IT security systems
- Router configuration
- Upgrading data servers and network equipment
- IP address auditing
- Liaising with project managers and service desk engineers
Who is hiring network engineers?
You can work for any company with its own large IT systems or work for companies that outsource their complete IT systems to specialists.
Typical companies and institutions hiring:
- Banks and financial institutions
- Government authorities
- Transport companies
- Companies in retail

Increased concerns about Internet security and the complexity of computer networks and systems has led many employers to find network engineers who received certifications related to the networking products they use. Among products commonly used by employers, credentials such as Cisco (CCNA Course in Chennai), Microsoft or Juniper certifications are often required by employers. These types of certifications show a network engineer’s abilities to successfully design, maintain and secure specific networking systems in accordance to the products’ requirements.
