How to Transition into Network Engineering/Administration with a Computer Science Degree

Starting your career as a network engineer/administrator without any prior experience can be challenging, but with the right approach, it's definitely achievable. In this article, we will discuss how to build a strong foundation, gain relevant credentials, and acquire hands-on experience to launch your career in network engineering or administration.

Learning the Basics

The journey begins with acquiring fundamental knowledge. While college classes can be a good starting point, they might not cover everything you need to know about networking. You can learn by:

Attending courses from major vendors like Cisco, which are specifically designed to teach networking fundamentals. Earning certifications such as the CCNA (Cisco Certified Network Associate), which is one of the most recognized credentials in the industry. Reading networking books and taking online courses from reputable platforms like Coursera, Udemy, or LinkedIn Learning.

It's important to keep in mind that most network administrators learn on the job. However, having these credentials will significantly increase your chances of securing an entry-level position.

Acquiring Credentials

To stand out in the job market, obtaining professional certifications is crucial. If you don't have a degree or certification in Computer Science, Networking, Telecommunications, or related fields, CCNA is an excellent starting point. It not only provides extensive knowledge but also hands-on experience with configuring and managing networks.

Leveraging Hands-On Experience

While credentials are essential, gaining practical experience is equally important. Here are some ways to achieve this:

Set up a home lab: As a friend and colleague did, acquire second-hand Cisco network gear (routers, switches, load balancers, etc.) and create a lab environment where you can learn networking, routing, proxies, firewalls, and security. Read and study: Supplement your learning with books and online courses. However, hands-on experience is invaluable and should not be replaced. Utilize online resources: Platforms like Cisco Learning, , and O’Reilly Learning offer comprehensive resources and courses.

Gaining Entry-Level Experience

Entry-level positions might be hard to come by, but they are possible. Start by:

Working in a help desk role to gain knowledge of operating systems, hardware, and networking. Using your free time to learn scripting (BASH, Python, PowerShell), configuration management (Ansible, Puppet), firewall routing, and other essential skills. Moving to a junior SysAdmin position once you have sufficient skills and experience.

Your ultimate goal should be to transition from a help desk role to a SysAdmin position. By doing so, you will gain valuable hands-on experience in network administration and increase your chances of securing a more senior network engineering role.

With dedication and effort, you can transition into a network engineering or administrative career even without prior experience. The key is to stay persistent, continue learning, and actively seek opportunities to gain practical experience.
