HPC Storage Systems Developer
Lawrence Berkeley National Laboratory
Berkeley, CA 94720
DescriptionHPC Storage Systems Developer - 97195
Division: NE-NERSC

Lawrence Berkeley National Lab’s (LBNL, https://www.lbl.gov/) NERSC Division has an opening for a HPC Storage Systems Developer to join the team.

NERSC is looking for a skilled systems programmer to help develop innovative software features for extreme-scale storage systems. In this position, you will join the Storage Systems Group which is made up of system engineers and programmers providing NERSC’s 300 petabyte High Performance Storage System and center-wide file systems. Our storage systems are utilized by more than 8,000 scientists who use NERSC to perform unclassified, scientific research across a wide range of disciplines, including climate modeling, research into new materials, simulations of the early universe, high energy physics and a host of other scientific endeavors. The majority of your time will be spent developing, testing and deploying storage systems software, tools and scripts, but you should be flexible and willing to take on troubleshooting and system administration tasks in support of our production environment.

In this exciting role, you will work with a team of software engineers who develop the High Performance Storage System (HPSS) and supporting software. HPSS is a premier high-performance archive software and is deployed at some of the world’s largest computing centers to meet the most challenging long-term and scalable-storage requirements. Jointly developed by five Department of Energy labs and IBM, you will collaborate daily with this geographically distributed team, taking on a variety of development tasks. The storage applications and features you create will become part of our production storage systems, and will be used by HPSS sites around the globe, including our production storage systems at NERSC. In addition to working on HPSS releases, you will also assist with supporting the production version of the software and its local applications at NERSC.

In addition to working on HPSS, you will help evaluate and shape new storage technologies to meet the evolving needs of NERSC’s high-performance computing users, and work on local development projects to improve the storage resources we offer. This includes exploration of object-based storage systems, advanced high-performance data transfer tools, implementation improvements for automated data migration between file systems and the archive, and evaluation of storage software built using new storage hardware technologies.
