Network Engineer
Design and manage enterprise networks, structured cabling, and converged communications infrastructure.
What Network Engineers Do
Network engineers design the communication backbone of organizations. This encompasses structured cabling (copper and fiber per TIA-568), LAN/WAN switching and routing, wireless networks (Wi-Fi 6/6E, cellular), network security (firewalls, VPNs, NAC), and unified communications (VoIP, video).
In building construction projects, low-voltage / network engineers prepare network design drawings showing telecommunications room layouts, cable pathways, equipment racks, and wireless access point placement. They must understand BICSI standards for cabling infrastructure and coordinate with electrical engineers for conduit and power (including PoE calculations for IP cameras, phones, and access points).
Enterprise network engineers work with Cisco, Juniper, Aruba, and other vendor equipment, configuring VLANs, routing protocols (OSPF, BGP), QoS, and network monitoring. Cloud networking (SD-WAN, SASE, AWS/Azure networking) is increasingly important, blurring the line between traditional network engineering and cloud architecture.

What certifications help a Network Engineer?
Commonly pursued credentials include CCNP Enterprise, CCIE, CompTIA Network+. The right certification depends on your specialty and employer; see the certifications table above for issuing bodies and notes.
How long does it take to become a Network Engineer?
Degree or self-study → CompTIA Network+ → CCNA → CCNP → 5+ years → CCIE or senior engineering
Is Network Engineer a good career?
Network engineers design, implement, and manage enterprise IT networks — from structured cabling and switching to routing, wireless, and network security. They ensure reliable, secure connectivity for businesses and critical infrastructure. CCNP and related certifications are key credentials. Demand is driven by ongoing infrastructure, construction, and technology work, and pay rises substantially with experience and licensure — from $80,000–$100,000 to $150,000–$200,000+.
