What You Will Do

Join the High Performance Computing Operations Group (HPC-OPS) in operating and maintaining some of the fastest supercomputers in the world. Designing, operating and maintaining these systems requires highly skilled personnel that specialize in both the hardware and software aspects of High Performance Computing. Innovators at heart, HPC-OPS Linux Administrators work both independently and collaboratively to maintain and implement capability improvements across a complex computing environment. This team is currently building on-premise cloud-like infrastructure to support the AI/ML/LLM needs of the laboratory.

The Platforms Team is seeking to add highly knowledgeable and motivated team members to help build and deploy the AI/ML/LLM infrastructure for LANL. This person will be an expert Linux Administrator who will help design, build and run our production NVidia DGX/HGX pods optimized for our environment and workflow. They will run and manage both admin and user-facing services with an understanding of modern AI/ML/LLM user workflows, Kubernetes, and other common tools. The successful candidate will participate in periodic on-call responsibilities managing NVidia SuperPods and Kubernetes clusters, while actively growing their technical skills and staying up to date with the latest technologies in the field. In addition, the selected candidate will have the opportunity to develop technical products such as technical documentation, presentations, technical papers, and reports, to communicate findings internally and at conferences.

The selected HPC Cluster/ Nvidia SuperPod Linux Administrator (Scientist 2/3) will provide strategic design, testing, analysis, administration, configuration management, verification, and validation of the newly developed cloud-like infrastructure and specialized compute infrastructure for AL/ML workloads. Mentoring of students, junior staff, and peers in technical and professional growth activities is highly valued, as is maintaining state-of-the-art technical expertise and knowledge within HPC system administration and developing new skills in related disciplines. This is your chance to directly support our national security mission and continue to make LANL the best place to work as a member of a dynamic, team-oriented, and leading-edge technical capability team.

This position will be filled at either the Scientist 2/3 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.
