Network Engineer Job Description (2026): Duties, Skills and Salary
A network engineer designs, builds and maintains the networks that connect offices, data centers and cloud environments: routers, switches, firewalls, VPNs and the wireless that everyone takes for granted until it breaks. They plan capacity, harden security, troubleshoot outages and keep an eye on performance before small issues become company-wide incidents.
Network engineers work in-house at companies with their own infrastructure, at managed service providers supporting multiple clients, and at ISPs and telecoms building the networks everyone else relies on. The job rewards people who are calm under pressure, since network problems tend to be visible to everyone the moment they happen.
