Los Alamos National Laboratory HPC Data Storage Administrator (Scientist 2/3) in Los Alamos, New Mexico
What You Will Do
The High Performance Computing (HPC) Division at Los Alamos National Laboratory provides scientific computing resources consisting of some of the largest HPC systems in the world, including a large (19K+ node) Cray system called Trinity, as well as numerous large commodity cluster systems. The High Performance Computing (HPC) Data Storage Teamwithin the HPC Systems Group (HPC-SYS)provides vanguard production support, research, and development for existing and future systems that feed and unleash the power of our supercomputers. The Data Storage Team designs, builds and maintains some of the largest, fastest and most complex data movement and storage systems, including systems supporting 100 Petabytes of capacity. We provide storage systems spanning the full range of tiers from the most resilient archival systems to the pinnacle of high-speed storage, including all-flash file systems and systems supplying bandwidth that exceeds a terabyte per second as part of LANL’s world-class supercomputing capability.
Innovators and builders at heart, the Data Storage team seeks highly motivated, productive, inquisitive, and multi-talented candidates who are equally comfortable working independently as well as part of a team. There are frequent opportunities for collaborative work with scientists and staff within the group (for instance with scientists designing and operating our high-speed networking infrastructure) or with scientists from other groups, including close collaborative research opportunities with LANL’s Ultrascale Systems Research Center (USRC), to help drive cutting edge advances.
This role requires strong communication skills, as well as comprehensive troubleshooting and analytical skills. Team member duties include: designing, building, and maintaining world-class data movement and storage systems; evaluating and testing new technology and solutions; system administration of HPC storage infrastructure in support of compute clusters; diagnosing, solving, and implementing solutions for various system operational problems; tuning file systems to increase performance and reliability of services; process automation; interacting with vendors; and communicating and collaborating with other groups, teams, projects and sites.
The selected candidate will participate in a regularly scheduled rotation of on-call support of production systems, including some systems under 7x24 hour support. In addition, some non-standard working hours may occasionally be required. This position is full-time and is located at Los Alamos National Laboratory in Los Alamos, New Mexico.
This position will be filled at either the Scientist 2 or Scientist 3 level, depending upon the skills of the selected candidate. Additional job responsibilities (outlined below) will be assigned if the candidate is hired at the higher level.
