Summary

Berkeley Lab is seeking an experienced Network/Software Engineer to join the Energy Sciences Network's (ESnet) Network Engineering Group (NEG). Funded by the US Department of Energy's Office of Science, ESnet is operated and managed by the ESnet staff at Lawrence Berkeley National Laboratory. ESnet provides innovative network services to the Office of Science research laboratories as well as other DOE sites; tying them both directly to Research and Education networks worldwide and the greater Internet. ESnet services allow scientists to make effective use of unique DOE research facilities and computing resources, independent of time and geographic location. The demand for fast and highly available networks by the scientific community leads to a challenging, fast-paced environment and the opportunity to assist the progress of important scientific research by providing critical network services. As the next step in high-speed networking, ESnet has been funded to build a demonstration 100Gbps wide area prototype network. ESnet is looking for an exceptional individual to be a part of the ESnet team.

Specifically, you will:

 * Work with Senior Engineers, ESnet site personnel, the staff of other network service providers and vendors to     support ESnet.

 * Design and implement ESnet's routing and switching architecture, network services (such as MPLS, QOS and IP multicast), network security, network monitoring, network measurements, line/site upgrades and the configuration of ESnet routers and switches as part of NEG responsibilities.

* Serve as principal point of contact for the network and resolve escalated (3rd level) trouble calls on a rotating basis.

* Work with a Senior Engineer to maintain the system that processes and displays ESnet traffic flow data.

* Analyze NetFlow data to find new persistent, high-bandwidth traffic flows that can benefit from using the ESnet-developed On-demand Secure Circuits and Advance Reservation System (OSCARS).

* Enhance the system to meet new requirements and interface with other network data collection and display tools as required.

* Participate in the creation of a requirements document and participate in the search for a vendor to replace the current homegrown system.

 

Computer Systems Engineer (CSE) 3:

In addition to the responsibilities of the CSE 2 listed above, the CSE 3 will:

* Work with ESnet site personnel, the staff of other network service providers and vendors that support ESnet.

* Assume responsibility for the system that processes and displays ESnet flow data.

* Write system requirements document, initiate, and lead the search for a product to replace the current     homegrown system.
