What You Will Do
High performance computing is a powerful tool that when put into the hands of creative minds is helping humanity solve its hardest problems. Supercomputers help us see structure in the chaos, find signals in the noise, and turn trillions of data points into answers to unlock radical innovation. The High Performance Computing (HPC) Platforms Team provides vanguard system and runtime support for some of the largest and fastest supercomputers in the world, including multi-petaop systems (e.g., the recently deployed 40 Peta operations per second Trinity Supercomputer).
Troubleshooters and problem-solvers at heart, the HPC Platforms Team seeks highly motivated, productive, inquisitive, and multi-talented candidates who are equally comfortable working independently as well as part of a team. The successful applicant will acquire the skills needed to take a leading role in working on all aspects of LANL’s HPC cluster administration. A broad range of expertise and background is desired in the team, and there are multiple projects that a successful candidate can pursue within the production and research disciplines of the 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 networks or data storage 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: system deployment, configuration, and full system administration of LANL’s world-class compute clusters; evaluating and testing new technology and solutions; diagnosing, solving, and implementing solutions for various system operational problems; system administration of HPC network infrastructure in support of compute clusters; diagnosing, solving, and implementing solutions for various system operational problems;system software management and maintenance, including security posture maintenance; tuning operating systems to increase performance and reliability of services;developing tools to support automation, optimization and monitoring efforts; 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.
Scientist 2 ($87,800-$144,800)
Participate in periodic on‐call responsibilities.
Work both independently and collaboratively with other system administrators, as well as under the supervision and guidance of senior HPC system administrators to provide technical assistance in problem solving, configuration management, and day-to-day operation of various supercomputing systems.
Troubleshoot, diagnose root cause, and isolate the components / failure scenarios while working with internal & external stakeholders.
Participate in process improvement, including deep multi‐system problem isolation and resolution often in collaboration with administrators of other HPC subsystems.
Develop and publish updates on resolutions and communicate findings internally.
Work with team members to make modifications and additions to existing code, methods and procedures.
Work with team to bring up new hardware and test functionality.
Work with team members and vendors to document, design, and implement new ideas and approaches for newer system administration and configuration tools and strategies and improve those for existing ones.
Present best practices, experience reports, and/or research results to managers and to peers locally or at conferences.
Scientist 3 ($96,600-$161,300)
In addition to the duties outlined above, a successful Scientist 3 candidate will be required to:
