DEPARTMENT OVERVIEW

The Earth Section of the Scripps Institution of Oceanography encompasses research in the Cecil H. & Ida M. Green Institute of Geophysics and Planetary Physics (IGPP) and the Geosciences Research Division (GRD). Research in IGPP spans a broad range of topics in geophysics including seismology, geodynamics, geodesy and crustal deformation, geomorphology, planetary physics, geomagnetism and paleomagnetism, oceanography and electrical methods.

The San Diego Supercomputer Center (SDSC) has a national reputation as a pioneer and leader in high-performance and data-intensive computing and cyberinfrastructure. Located on the campus of UC San Diego, SDSC provides resources, services and expertise to the national research community including industry and academia.

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.

POSITION OVERVIEW

Under direction of the senior network architect, this position is responsible for managing the overall network cyberinfrastructure that supports the research and public safety end-users of 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. As needed, the Wide-area Wireless Network Administrator assists with other HPWREN-led wireless projects. 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.

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. The Wide-area Wireless Network Administrator also meets with colleagues from other network operators in to design and deploy infrastructure services that support common needs from different institutions.

The Wide-area Wireless Network Administrator primarily works from La Jolla , but will occasionally need to work irregular hours to resolve critical operations issues or assist with deployment of equipment at tower and customer sites.
