Join the High-Performance Computing Systems Group (HSG) at NCAR and help power cutting-edge Earth system science! As an HPC Systems Engineer, you will play a pivotal role in engineering and managing CISL's world-class computational, storage, archival, and networking platforms. This dynamic position offers the unique opportunity to work with advanced multi-vendor architectures, collaborate with top scientific talent, and solve complex technical challenges at scale. You will directly support state-of-the-art supercomputing infrastructure housed at the premier NCAR Wyoming Supercomputing Center (NWSC) in Cheyenne, Wyoming, engaging on-site during system deployments, major upgrades, and innovative troubleshooting initiatives. CISL advances Earth system science research by providing scientists with large-scale computing capabilities, platforms for sharing and discovering Earth system science data, and innovative AI/ML and analysis tools. CISL scientists engage in computational science, data assimilation, and machine learning. CISL supports thousands of researchers annually and fosters the next generation of scientists and cyberinfrastructure professionals through our educational programs. CISL operates Derecho, one of the world's most powerful supercomputers dedicated to open Earth science research; manages the Geoscience Data Exchange (GDEX), a trusted platform for sharing and stewarding Earth system science data and model output; leads efforts to transform how NSF NCAR develops and optimizes scientific software; and develops software products for data assimilation, data analysis, and other workflow needs. NSF NCAR's integrated research computing and data environments are housed at the NSF NCAR-Wyoming Supercomputing Center (NWSC) in Cheyenne, Wyoming. Where You Will Work: Desired, but not required KSAs Experience with the Chameleon cloud research platform. Additional Information Work Location Expectations: This position is open to candidates seeking in-person or hybrid (combination of 3 days in-person and 2 days of remote) opportunities. UCAR requires ALL positions to be performed within the U.S., excluding U.S. Territories. Responsibilities Systems Engineering & Management Perform installation, hardware and software integration and engineering, maintenance, administration, troubleshooting, and operation of both software and hardware systems, including petascale computational systems, scheduling environments, high-speed networks, and storage systems. Use tools for system management, system deployment, system monitoring, system resource control, system statistical data gathering, data transfer services, data management services, data archiving services, Cloud services, network services, performance tuning, and system benchmarking. Operational Monitoring and Troubleshooting Operate and monitor the behavior of the group's systems and related hardware on a routine, daily basis to ensure proper and efficient operations. Alert other HPC Systems Group staff, vendor representatives and/or CISL Operations staff of anomalistic conditions or behaviors, as appropriate, and take remedial actions as necessary. Diagnose and may repair failed hardware components. Provide advanced service on a 7x24 on-call basis to troubleshoot and resolve system related problems presented by users, other sections in CISL, and vendor-employed engineers and analysts. Consult with other staff as appropriate to solve issues. Organizational Representation and Reporting Provide regular HPC Systems Group activities reports to management and may contribute to the NCAR Annual Scientific Report and development plans. Attend group, divisional, and lab meetings and may represent the HPC Systems Group and its activities at such meetings. May represent the group at larger organizational meetings as necessary (this may include presenting to both internal and external user groups, at supercomputing focused conferences, and organizational planning meetings).
