Wireless Network Engineer

Project context

Project context

This position carries wireless expertise for a large campus estate spanning roughly one hundred sites. It is the most exposed of the five profiles, because the LAN and Wi-Fi scope is the first to transfer from the outgoing supplier.

The holder is expected to be a genuine wireless specialist, not a generalist with wireless exposure, deep expertise in Cisco Enterprise Wireless technologies and a strong understanding of RF engineering principles. The candidate must be able to analyse, troubleshoot and optimise wireless environments from both infrastructure and radio perspectives, rather than solely through controller or configuration management.

Moreover, he must carry the monitoring of that estate as a second skill.
