Network Engineer II

Johns Hopkins Public Safety is seeking a Network Engineer II who will be responsible for planning, forecasting, implementing, and identifying resource requirements for network backbone infrastructures (inclusive of wireless technologies) of moderate complexity to support the Johns Hopkins Police Department (JHPD) and the Johns Hopkins Public Safety (JHPS). The scope of this position typically affects the delivery of campus backbone network resources for a number of local and wide area connected buildings. Troubleshoot, monitor and maintain network components and functionality on a campus/enterprise-wide level. Position provides consultation to JHPD IT users in designated business units for aspects of network connectivity functions, issues of increasing traffic, and determining the path between hosts across the network and AT&T FirstNet.
