Network Engineer
Designs, builds and upgrades networks - routing, switching, WAN links and redundancy - and is the escalation point when the network misbehaves.
What the job involves
A network engineer designs, builds and improves networks. The work covers choosing routing and switching designs, planning addressing and redundancy, connecting sites over WAN links and VPNs, and solving the complex faults that day-to-day administrators escalate.
Where the work is
Telecom operators and internet service providers, banks, large public institutions and government data centres, universities, systems integrators and equipment suppliers, and the regional offices of international organisations.
How people get into it
The usual route is a degree in computer, electronic or telecommunications engineering, followed by several years in network administration or support. Deep routing and switching knowledge, often proven with CCNA and later CCNP, is what moves people into engineering posts.
