What is a Network Engineer?
Computer network engineers are awesome professionals with the exciting job of designing and building data communication networks. They also get to monitor network systems to ensure everything runs smoothly. These can vary in size, from a simple connection between a few offices to a complex cloud infrastructure that supports a multinational company.
Network engineers have the vital task of safeguarding networks from various external threats, such as phishing schemes, ransomware, and denial-of-service attacks. This is done through a process called network security. In smaller companies, you can handle both architecture and security responsibilities. In larger companies, it’s common to focus on a specific area of network engineering, like architecture, security, or administration.
What Does a Network Engineer Do?
Network engineers are awesome! They have the important job of designing, building, implementing, and maintaining computer networks for businesses and organizations. These networks usually consist of a company’s phone system, intranet, and extranet. They are also in charge of assessing how well each system is performing, taking care of regular maintenance, figuring out what’s wrong when there are issues, and fixing any problems that come up. Additionally, a network engineer’s job responsibilities may include:
- Taking care of computers and their accompanying hardware, software, and networks
- Implementing data security systems, maintaining data backups, managing firewalls, and upgrading anti-virus software are all essential tasks in ensuring the safety of sensitive data.
- Setting up and configuring many types of network hardware, including but not limited to routers, switches, load balancers, virtual private networks, wide area network accelerators, and proxy servers
- Maintaining a high standard of network performance through constant monitoring and troubleshooting
- Scheduling updates, upgrading networks, monitoring security settings, and installing patches and service packs are all examples of routine maintenance.
- Working together with outside providers and support services to guarantee a network’s top performance
Career Path to a Network Engineer
10 Tips to Become a Network Engineer
- Get a useful education: Entry-level jobs in network engineering usually require a bachelor’s degree in computer science, IT, or a similar field. Some employers may also look for individuals with a master’s degree. This formal education will give you a strong foundation in networking ideas and technologies.
- Gain Technical information: Learn networking-related technical skills and information. Study networking basics, protocols, network design concepts, routing and switching, network security, and wireless networking. Learn about the devices and technologies used in the business for networking.
- Obtain vendor-neutral certifications: Some certifications aren’t tied to any one vendor that can help you show potential companies your skills and knowledge. Cisco Certified Network Associate (CCNA), Cisco Certified Network Professional (CCNP), and CompTIA Network+ are all well-known certifications for Network Engineers.
- Choose the right way for your device: Cisco and Juniper are the two main device tracks in networking. Once you’ve decided on a plan, you’ll need to get certifications from each vendor.
- Get Real-World practice: Look for ways to get real-world practice with networking. Look for volunteer work, internships, or entry-level jobs that give you the chance to work with network systems and technologies. This hands-on training will help you better understand networking problems in the real world.
- Build a Lab Environment: Set up a lab setting where you can try out networking ideas and practice them. This could mean buying networking equipment or using technologies like Cisco packet tracer or GNS3 virtualization to build a simulated network environment.
- Stay up to date: tools and trends in networking change quickly. Keep up with the latest news, changes, protocols, emerging tools, and best practices. Use online tools, industry publications, forums, and conferences, read technical blogs, and sign up for online courses or webinars to keep learning.
- Develop your soft skills: Network engineers need to be good at both technical and “soft” skills, such as conversation, problem-solving, and working in a team.
- Connect with other people in your field: Make connections with other workers. Networking with other professionals is an excellent method to discover new job possibilities and keep up with the latest trends. You can network at business events, in online forums, and on social media like Linkedin.
- Apply for jobs:
- Once you’re sure of your skills and information, start looking for jobs in network engineering through Indeed.com, seek.com, Linkedin, jobstreet.com, and glassdoor.com.
- Make sure that your resume and cover letter show the skills and experiences that are most important to you.
- Review and practice your answers to common networking interview questions and Network engineer interview videos to prepare for jobs.

What Should I Practice for Network Engineering Interview?
- Networking Basics: Make sure you have a solid idea of networking concepts like the OSI model, network types, topologies, TCP/IP, subnetting, routing, switching, and VLANs.
- Network Protocols: Learn about TCP, UDP, HTTP, DNS, DHCP, SNMP, and BGP, which are all popular network protocols. Learn what their jobs are and how they work in a network.
- Network Devices: Learn about networking tools such as routers, switches, firewalls, load balancers, and proxy servers. Learn what they do, how they work, and how they affect each other.
- Routing and Switching: Learn about routing algorithms such as OSPF, EIGRP, and BGP. Learn about routing tables, routing measures, routing algorithms, and switching technologies like Spanning Tree Protocol (STP) and Virtual LANs (VLANs).
- Network security: Know about authentication, permission, encryption, VPNs, firewalls, IDS/IPS systems, and safe protocols like SSL/TLS.
- Troubleshooting a network: Use tools and methods like ping, traceroute, Wireshark, and network tracking systems to learn how to fix a network. Be ready to show that you know how to find and fix common network problems.
- Network Design and Architecture: You should know the basic rules of network design, such as topology, scale, redundancy, and high availability. Learn how to create and set up networks that meet certain needs.
- Cloud networking: Learn about cloud networking concepts, such as virtual networks, VPN connections to cloud providers, and networking services that are special to the cloud, such as AWS VPC, Azure Virtual Network, and Google Cloud VPC.
- Network Monitoring and Management: Learn how to use tools like SNMP, NetFlow, Syslog, and configuration management systems to monitor and control networks. Learn how these tools are used to watch networks and fix problems.
- Learn to code in the right languages: To work as a network worker, you don’t always need to know how to code. But knowing a few programming languages can make you a better job candidate and help you do your work better. Different organizations like different computer languages, but Python, Perl, Bash, and Golang are popular ones to think about.
It’s important to research any organization-specific standards or technologies that are directly related to the position you’re looking for. Keeping updated on networking news and developments is also a great way to show your interest in and commitment to the sector.
