Networking Administrator - 138100

The High Performance Wireless Research and Education Network (HPWREN), a University of California San Diego partnership project led by the San Diego Supercomputer Center and the Scripps Institution of Oceanography's Institute of Geophysics and Planetary Physics, supports Internet-data applications in the research, education, and public safety realms.

HPWREN functions as a collaborative, Internet-connected cyberinfrastructure. The project supports a high-bandwidth wireless backbone and access data network in San Diego, Riverside, and Imperial counties in areas that are typically not well-served by other technologies to reach the Internet. This includes backbone locations, typically sited on mountain tops, to connect often hard-to-reach areas in the remote Southern California back country.

The Networking Administrator applies advanced IT concepts and multi-institutional objectives to resolve highly complex, cross-domain technical issues requiring in-depth evaluation of variable factors. Independently designs, operates, and maintains SIO IGPP's 24/7/365 high-availability distributed computing infrastructure supporting continuous streaming data acquisition from the HPWREN network. This includes overseeing management of the network segments and firewalls in use on each mountain-top hub site, as well as directly managing the network space in the data centers that host the servers for the network. The position performs in-depth analyses and implements solutions for highly complex issues in a number of technical areas:

• Administration of network management platforms such as Netbox;
• Management of enterprise network switches and routers from vendors such as Cisco and Mikrotik;
• Management of enterprise firewall devices from vendors such as Fortinet;
• Management of server and network log aggregation and analysis platforms such as Splunk;
• Management of terrestrial microwave radio systems from vendors such as SIAE, Ubiquiti, Radwin
• Implementation of secure configurations to minimize trust relationships between network segments.

Note that the responsibilities of this position are focused on HPWREN backbone and edge network infrastructure management, but expertise and occasional assistance with server infrastructure issues is required.

In collaboration with San Diego County Fire Authority IT and UCSD ITS staff, the position implements architecture reference designs of a shared cyberinfrastructure platform across the network backbone that also supports common needs from different institutions.
