Los Alamos National Laboratory Archive Storage System 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 Team within 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 the supercomputer. The Data Storage Team designs, builds and maintains some of the largest, fastest and most complex data movement and storage systems in the world, 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 to some of the largest and fastest supercomputers in the world.
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. Specifically, the selected candidate will support Archival storage in both production and forward looking efforts. The role will likely include database administration in addition to general storage administration.
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 members of the archive team or group after receiving initial direction and requirements from technical project leads.
Troubleshoot, diagnose root cause of system failures, and isolate the components / failure scenarios while working with internal & external stakeholders
Develop and publish updates on resolutions and communicate findings internally.
Work with team members to make modifications and additions to existing systems, code, and methods.
Work with team to bring up new hardware and test functionality.
Participate in process improvement, including deep multi-system problem isolation and resolution often in collaboration with administrators of other HPC subsystems.
Work with team members to document, design, and implement new ideas and approaches for newer architectures 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:
Work as a technical leader/subject matter expert to propose and implement solutions to current problems and future deficiencies in our HPC archive storage environment in conjunction with junior and senior administrators and technical staff within and across teams.
Proactively create experiments and tooling to validate solutions and to detect and diagnose hardware health issues.
Analyze published research papers in the area of archive and data storage, summarize, and share implications and connections to ongoing work with team members.
Interact and/or collaborate with people from other teams, groups, divisions, directorates, and programs to develop, implement, and/or communicate technical solutions.
Enhance technical and professional expertise of other staff and students through active mentoring and training activities.
Contribute to peer review of the work of others across organizations or disciplines within the laboratory.
Present best practices and research results to national peers at conferences, workshops, and meetings, as well as participate in national strategic partnerships.
