HPC Systems Integration Engineer 4 - 130890

The Mission of the San Diego Supercomputer Center is to translate innovation into practice. SDSC adopts and partners on innovations in industry and academia in the areas of software, hardware, computational and data sciences, and related areas, and translates them into cyberinfrastructure that solves practical problems across any and all scientific domains and societal endeavors. Cyberinfrastructure refers to an accessible, integrated network of high-performance computing, data, and networking resources and expertise, focused on accelerating scientific inquiry and discovery. With more than 250 employees and $30-50M of revenue a year, SDSC is a global leader in the design, development, and operations of cyberinfrastructure.

SDSC supports hundreds of multidisciplinary programs spanning a wide variety of domains, from earth sciences and biology to astrophysics, bioinformatics, and health IT. SDSC presently operates multiple large HPC systems ranging from a 120k x86 CPU core general purpose system to a system explicitly designed for Artificial Intelligence and Machine Learning, and a nationally distributed system open for all of academia to integrate with. SDSC offers research data services across the entire vertical stack from universally scalable storage to consulting services on FAIR, Big Data, and AI. SDSC offers a rich set of cloud services both on-premise, in the commercial cloud, and as hybrid services across both.

SDSC has three geographic scopes, a national scope supporting cyberinfrastructure for the entire US research and education community, a California scope with a special focus on convergence research that addresses the three dominant threats to CA: Drought, Fire, Earthquakes, and a campus scope focusing on advancing the global impact of SDSC by advancing the research objectives of the UC San Diego faculty, researchers, and students. SDSC impacts researchers at scales from 1,000's to Millions. SDSC annually trains thousands of researchers in cyberinfrastructure tools and software, and supports thousands of individual researchers via Unix accounts on its large HPC systems. SDSC was a leader developing the Science Gateway concept, and continues to be a global leader in its evolution. SDSC operates multiple major such gateways with user communities ranging from the tens of thousands to the millions. SDSC's educational programs includes online courses that have been attended by more than a million students.

SDSC is committed to democratizing access to cyberinfrastructure across all of its geographic scopes. SDSC strives towards a culture that supports our employees to be their best, achieve their goals, and enjoy their lives, both professionally and personally.

SDSC's High-Performance Systems Group is responsible for and operates SDSC's high-performance computing clusters and related systems. The group operates large-scale compute and storage systems funded by the National Science Foundation (currently the XSEDE program), the UC San Diego campus (e.g., the Triton Shared Compute Cluster) and other entities; these systems support users from campus, national, and international communities across a broad range of scientific disciplines. The group is part of SDSC's Data-Enabled Scientific Computing (DESC) Division.

POSTION OVERVIEW:

The incumbent will apply advanced systems and software integration concepts, and location or institutional objectives, to resolve highly complex issues where analysis of systems and software requires an in-depth evaluation of variable factors to resolve and implement medium to large projects of broad scope and complexity. They will regularly resolve highly complex business processes, system functionality, implementation issues, and system and software integration issues where analysis of situations or data requires an in-depth evaluation of variable factors. They will select tools, methods, techniques, and evaluation criteria to obtain results, give technical presentations to associated team, other technical units, and management as well as evaluate new technologies including performing moderate to complex cost/benefit analyses. The incumbent may lead a team of systems/infrastructure professionals.

This position has primary responsibility for Triton Shared Computing Cluster, a UC San Diego computing resource operated on behalf of the UC San Diego research community. TSCC comprises approximately 300 general computing and GPU nodes and is designed to grow as more researchers participate. In this capacity, the incumbent interacts with condo owners to provide access to the computational resources and software required for their research, develops policies to ensure reliable and efficient cluster operation, and works with user support staff to provide effective support while balancing competing and sometimes incompatible needs and desires from different laboratories to ensure equitable treatment of different projects.

The incumbent also provides project, system administration support, and on-call duties for other resources at SDSC including but not limited to: Expanse, an NSF-funded supercomputer operated on behalf of the national research community; Popeye, an HPC resource managed for the Simons Foundation; Voyager an AI supercomputer and Cosmos which will be deployed in late 2024.

The incumbent works extensively with members of the SDSC HPC systems group to coordinate operations between TSCC and SDSCs other HPC systems and storage. The position involves researching existing cluster operations, monitoring, and reporting tools as well as designing, implementing, and documenting new ones. In this role the incumbent may lead the design and implementation of new high performance cluster resources, determining the best architecture solutions using state-of-the-art computational, storage, and network technologies. They will oversee multiple vendor proposals, evaluating the relative strengths and weaknesses of each to determine the best solution for continued cluster operations and expansion. TSCC and other cluster operations rely on various cluster management systems including Rocks and Bright. The position requires detailed knowledge of these or similar cluster management tools to maintain the configuration state of all managed systems. Knowledge of version control systems such as GIT is required to track system changes.
