Network Engineer Career


What Is a Network Engineer?


One of the best paying and most stable roles within networking is that of a network engineer. Working closely with other key IT roles, like network administrators, these networking engineers design, build, and maintain networks for optimal performance. And if you secure an engineering role in this burgeoning field, you’ll be responsible for managing the foundation of your organization’s IT networking system.

As a network engineer, you’ll open the door to a world of benefits and opportunities. In addition to working with a diverse group of employees and departments, you’ll be able to continue learning and growing as you stretch to think outside the box. Add to that the ability to earn a fantastic salary while working with technology (something you undoubtedly love), and you’ll enter a profession that can provide a lifetime of stable, rewarding employment.


What Does a Network Engineer Do?

Nearly every business has a network that keeps it running. These networks can include an organization’s phones, computers, routers, intranet, and extranet. It’s the job of a network engineer or network administrator to plan, implement, and manage these business-critical systems—which is why it’s such a valued, well-paying role.

As this kind of engineer, your daily activities and responsibilities will include:

  • Configuration—installing routers, VPNs, proxy servers, switches, WAN accelerators, and load balancers.
  • Maintenance—scheduling network updates, performing upgrades, and installing patches or service packs.
  • Performance—monitoring and troubleshooting network systems for new ways to improve performance.
  • Security—performing data backups, updating virus protection software, and implementing new network data security systems.
  • Optimization—working with external service and support vendors to ensure optimal network operation.

What Is the Difference Between Network Engineer and Network Administrator?

Many organizations mistakenly use the terms network engineer and network administrator interchangeably. The two roles, however, perform different functions entirely, with a network engineer typically having greater executive responsibilities than a network administrator. 

Network engineering involves dealing with the planning, design, and technical specification of a project. Professionals in this field are generally curious about how things work and can understand the complexity of networking.

Network administrators typically perform organizational tasks, which involve the day-to-day maintenance, management, and troubleshooting efforts of IT projects. An effective network administrator will have a strong knowledge of hands-on administration of the network’s equipment through courses and vendor documentation. Education toward becoming a network administrator provides a foundation for understanding the objectives of the network design, along with the knowledge to quickly diagnose problems. 

Along with the different education paths that both professions require, salary expectations are also a key difference between the two roles. The annual salary for a network administrator falls within the range of $65,000 to $100,000, while the network engineer’s annual salary is between $75,000 and $110,000.

What Is a Typical Day in the Life of a Network Engineer?

Within this vast and dynamic field, the daily responsibilities of a network engineer are wide ranging. While most engineers work on specific tasks unique to the job, many companies or organizations may require a divergence in roles and responsibilities. On a typical day, network engineers will participate in any or all of the following activities

  • Maintaining computer networks including mainframes, VPNs, routers and other physical hardware.
  • Installing and configuring network equipment.
  • Creating firewalls and updating virus protection software and data security systems to keep data and communications protected.
  • Monitoring computer systems to improve network performance for all systems.
  • Troubleshooting, resolving, and communicating networking issues to other employees and management.
  • Implementing disaster recovery procedures. 
  • Maintaining current knowledge and understanding of security and networking. best practices to offer the best solutions and protection to company systems.


How Do I Become a Network Engineer?

Earn a Bachelor’s Degree to Become a Network Engineer

For entry-level network engineer jobs, you’ll first need to get your bachelor’s degree in network engineering, information systems, IT, or computer engineering. You can then gain critical on-the-job experience to become a valued member of your team and move up within your organization or onto other senior-level opportunities.

Since network technology changes quickly, you should also regularly take training and earn several information technology certifications (aka “certs”)—many of which may be required by your employer or for future roles. Cisco offers the premier certification for network engineering. Cisco is well known in the IT realm for having top certification options for this career path and, depending on where you earn your bachelor’s degree, some certs can be included with your coursework.

What Skills Does a Network Engineer Need?

Here's a list of skills a network engineer needs in order to be successful. 

Hard skills

As an extension of your education, on-the-job training, and certs, you’ll need the following hard skills to be successful in network engineering:

  • Networking. Knowledge of how to integrate WAN, LAN, SD-WAN, SD-branch, and other networks and architectures is a must.
  • Programming. You should know popular scripting languages for enterprise-grade networks like Ruby, Python, and Perl. Automation-friendly languages are helpful too, like Java, Ansible, and Terraform, since many network functions are becoming automated.
  • An understanding of infrastructure. You’ll be responsible for maintaining your network’s infrastructure and advising on what hardware it will reside on.
  • Domain-name system expertise. The internet was built on DNS, as are most of today’s enterprise networks, so you need to know how to troubleshoot it.
  • IoT knowledge. Some network architectures, like SD-branch, use Wi-Fi to support their loT ecosystems. And it’s expected to significantly impact enterprise network security, infrastructure, and traffic.
  • An understanding of security and firewalls. While your organization may have an IT security officer, you’ll still probably need to deploy and maintain network firewalls.
  • Virtualization abilities. You must be able to work with automated network functions like SD-WAN to optimize your network’s resources.
  • Ability to work with an MPLS network. Even though it’s being replaced by SD-WAN, working with an MPLS-exclusive (or hybrid WAN) network is still an essential skill.

You should also be well-rounded in other basic technical skills, like data research and data entry, since a lot of your job is centered on analyzing system performance.

Soft skills

Network administrators work on a variety of tasks and with a variety of people. So you’ll need a broad set of soft skills, including:

  • Communication—to effectively describe your challenges and solutions to non-IT employees and management.
  • Organization—to handle multiple tasks and issues simultaneously.
  • Analytical thinking—to ensure your network and systems perform reliably and proactively identify new requirements as needs evolve.
  • Problem-solving—to resolve issues as fast as possible to minimize network damage or downtime.
  • Time management—to keep numerous projects on track and meet ongoing deadlines.
