Job Description

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. This role communicates with end users about the scheduling and delivery of changes within the network topology and participates in the technical aspects of network changes and workflow. Design, implement change control processes, deploy and maintain network infrastructure in relation to requests for service in conjunction with vendors, technicians, and clients.

Position primarily focuses on moderately complex designs for JHPD data and security systems throughout the Johns Hopkins enterprise. Position may assist with more complex designs that involve a multitude of variables, multiple vendors, and a broader customer base. Job complexity includes design/engineering/installation of medium sized projects (multiple buildings to campus wide), troubleshooting moderately complex routing and switching protocol issues, and interfacing with customers to understand needs.

Focused at Johns Hopkins campus; however, this position is expected to travel throughout Maryland/DC to cover any Johns Hopkins location as required.
