How to Land Your First Job as a Network Engineer

One of the most important jobs in the modern workforce is that of a network engineer. Businesses worldwide, from the US to the UK and beyond, require skilled experts to plan, set up, and manage their networks. These systems serve as the foundation for day-to-day activities, facilitating secure communication and data sharing. Although there are many network engineer jobs available, it can be intimidating for newcomers entering the field. 

Securing that first position requires planning, effort, and strategy, regardless of whether you're looking at entry-level network engineer jobs or pursuing the network engineer career path further out. 

To get you started, this guide will walk you through the fundamentals.

The Demand for Network Engineers

Network engineers with the necessary skills are in high demand. The job market for network engineers is expected to grow by 5% from 2018 to 2028, with approximately 18,200 new jobs expected during this period.

In order to manage cloud-based solutions, secure their infrastructure, or guarantee smooth departmental communication, businesses rely significantly on connectivity. For tech enthusiasts who are passionate about networking, this dependence has opened up countless opportunities.

IT isn't just found in conventional tech firms. Complex and secure networks are necessary for the operation of hospitals, schools, financial institutions, retail chains, and even government agencies. The need for network engineers has increased across industries as a result of the growing popularity of technologies like cloud computing, cybersecurity, and the Internet of Things (IoT).

If you have the necessary abilities, credentials, and attitude, you can usually overcome the competition for entry-level network engineer positions. Although there are many opportunities on the job market, having a plan makes all the difference.

Building the Right Skill Set

Before you can enter the field, you need to develop a solid foundation. Every network engineer job description features certain core skills that any hiring manager will expect you to have. 

Graduates can build on their foundational skills by focusing on the following:

Routing and Switching

Networking revolves around moving data efficiently between devices, and a solid grasp of routing and switching is fundamental. Understanding routing protocols like OSPF and BGP, learning subnetting techniques, and configuring VLANs will make you a much more competent candidate. You’ll also need to understand switching concepts such as the spanning-tree protocol (STP) and how various network layers interact. Mastering these skills ensures you can design, build, and maintain reliable and scalable networks.

Troubleshooting

Networks are prone to issues like slow performance, dropped connections, misconfigurations, or even major outages. Employers value candidates who can quickly identify the root cause of problems and implement effective solutions. Using diagnostic tools like Wireshark for packet analysis and Nmap for network discovery can help tremendously. A structured troubleshooting methodology, such as the OSI model approach, is equally important for efficiently restoring normal operations.

Security Knowledge

Keeping a network protected from potential threats is a major part of a network engineer’s daily responsibilities. You’ll work with firewalls, VPN configurations, intrusion detection/prevention systems (IDS/IPS), and network monitoring tools to prevent cyberattacks and data breaches. A strong understanding of security principles, like least privilege access and encryption standards, will help you better secure network infrastructures against evolving threats.

Wireless Networking

With more organisations relying heavily on Wi-Fi for daily operations, understanding wireless architectures, standards like 802.11, and security protocols such as WPA3 is a definite advantage. You'll need to know how to plan and optimise wireless coverage, troubleshoot connectivity issues, and protect wireless networks from vulnerabilities like rogue access points and man-in-the-middle attacks.

Top Tip: Developing these skills isn’t something that happens overnight, but consistent effort goes a long way. You can start with online tutorials, coursework, or even self-paced certifications to get a deeper understanding.

The Importance of Soft Skills

While technical expertise is crucial, don’t underestimate the value of soft skills. These often make the difference between a good and a great network engineer:

• Problem-solving: Unexpected challenges will inevitably arise, and how you handle high-pressure situations often defines your performance. Being resourceful and thinking critically are essential traits.
