Some of us look at how networks help us do our jobs, while others look at the details of connections and data transfers. Network engineers must see both when designing systems that connect the world. They need a balance of creativity and analytical thinking—neither skill alone can help them build the best data communication network. If you’re creative and detail-oriented, a career in network engineering could be for you.
What is a network engineer?
Network engineers, sometimes known as network architects, are responsible for designing, planning, and implementing network infrastructures, including local area networks (LANs), wide area networks (WANs), and intranets. They work on high-level network architecture, often deal with complex network projects, and may specialize in specific areas, such as routing, switching, or security.
Some responsibilities of a network engineer include:
- Designing, deploying, managing, and troubleshooting networks
- Analyzing network traffic and predicting growth to determine future needs
- Presenting to leadership their plans and explaining how they meet the needs of the organization
- Understanding cybersecurity and how it affects networks
- Staying up to date on the latest technologies to determine the best options for their organization
Network engineers may share some responsibilities as network administrators; in some organizations, a network engineer and administrator may be the same. The network engineer focuses on designing and building networks in organizations that differentiate the role, while network administrators maintain and manage them.
How to become a network engineer vs. network architect
Many network engineers have a bachelor’s degree, and some have a master’s degree in a computer-related field such as computer science, programming, or engineering. But as with many IT roles, a college degree isn’t everything. Employers also look for relevant experience in IT systems or network administration. Network engineer jobs often require vendor-specific certifications for the systems used or vendor-neutral ones like CompTIA Network+.
To become a network architect, IT training and certifications, plus hands-on experience, prove to employers that you have the skills needed for jobs like Network Architect. CompTIA Network+, CompTIA Security+, and CompTIA CySA+ are great options for gaining the skills employers look for in Network Architects.
