HPC System Integration Software Architect (Scientist 3/4) 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. The Systems team within the HPC Design Group (HPC-DES) is responsible for defining the technical direction, evaluating, developing and deploying the tools and system software ultimately used in production support of LANL’s HPC resources. These HPC resources are some of the largest in the world and currently include a large (19K+ node) Cray system called Trinity as well as numerous large commodity cluster systems.

This position will be filled at either the Scientist 3/Scientist 4 level, depending on the skills of the selected candidate. Additional job responsibilities (outlined below) will be assigned if the candidate is hired at the higher level.

You will be working closely with other DES System team members as well as more production focused team members in other groups at the HPC division. Projects typically involve collaborations inside and outside of the Laboratory, in line with the Laboratories’ history of leadership in HPC. Some non-standard working hours may occasionally be required.

We seek candidates who want to make significant contributions that impact the HPC technical direction at LANL and ultimately across the DOE and the nation.

Scientist 3 ($96,600 - $161,300)

The successful candidate will be required to:

  • Identify current and future challenges faced by large scale HPC applications, and work toward production HPC system solutions. In particular, this individual will help design, develop, deploy, and support system software to overcome these challenges. Areas of interaction include distributed systems, data aware scheduling, resource allocation, workflow management, user tools, software environment, with a focus on delivering next generation programming and run time user environment.

  • Set direction, goals, milestones, and deliverables for project tasks and establish associated scope, schedule and budgets. Assist in the preparation of progress reports to sponsors.

  • Contribute to multi-lab and cross organization proposals for funding both internally and externally to the laboratory.

  • Will be the Principal Investigator for a targeted area of research.

  • Present results of work locally and at conferences and workshops.

  • Support system software investigations along with application performance and stability optimization and testing within the HPC integrated open and secure network infrastructure.

  • Assist in the design of data intensive solutions for the wider HPC environment and provide input into the design and specification of new venues that utilize custom system software.

  • Provide Tier 3 support to system admin staff and help desk staff on various HPC production systems, when required by user feature requests, bugs, or security vulnerabilities that cannot be resolved by production teams.

  • Set direction and goals for project tasks and establish associated scope, schedule and budgets.

  • Enhance technical and professional expertise of other staff through active mentoring and training.

  • Contribute to peer review of the work of others across organizations or disciplines within the laboratory.

Scientist 4 ($116,900 - $197,000)

In addition to the duties mentioned above, the Scientist 4 will be required to:

  • Lead proposals for both internal and external funding for self and others via responses to competitive requests for proposals.

  • Contribute to peer review of the work of others across organizations and disciplines nationally, including participation on HPC-related conference and workshop committees.

  • Participate in national review boards for DOE in subject area of expertise.

  • Acquire internal/external funding for self and others via responses to competitive requests for proposals and developed collaborations.

  • Work closely with high level project leads and program managers to insure their projects are successful.

  • Assist in defining specifications and RFP’s for new HPC systems.
