Required - GeneralTypically requires a bachelor's degree or equivalent certification in a related field, with a minimum of 5 years of experienceExperience using containers in an HPC context - packaging and running user environments (including older OS or older package versions) on a shared cluster rather than for traditional microservicesExperience building and supporting CI/CD workflows, ideally tied to HPC clusters and run nodesSystem configuration management experienceExperience with monitoring and alerting systemsDemonstrated problem-solving, planning, and communication skillsAbility to work effectively in a team environmentMust be able to provide proof of U.S. Citizenship or U.S. Permanent Residency and complete a U.S. government background investigation (required for this NASA contract - see Important Information below).PreferencesExperience with RedHat-based Linux distributionsFamiliarity with InfiniBand high-speed networkingExperience with provisioning tools (xCAT, Warewulf)Experience with Ansible and/or Foreman for configuration managementFamiliarity with SPACK software package managerExperience with log consolidation, monitoring, and Git/GitLab (including CI/CD pipelines)Familiarity with Jacamar (https://gitlab.com/ecp-ci/jacamar-ci) or comparable tooling for running CI/CD jobs against HPC clusters and run nodesExperience applying AI in a sysadmin role - integrating AI tooling into operational workflows, automation, and user-facing HPC jobsMPI workflow and administration experience (e.g., Open MPI, MPICH, Intel MPI)Package management and environment modules experience (e.g., Lmod/Environment Modules, SPACK, EasyBuild)Knowledge of NASA security mechanisms (security plans, POAMs, ATOs, Risk Assessments)This position has been posted at multiple levels. MRI Technologies, supporting NASA under the JETS II contract, is hiring an HPC Linux System Administrator to help run and improve that cluster - a hands-on, on-premises HPC role administering the job scheduler and parallel filesystem, supporting containerized HPC workflows and CI/CD (including Jacamar), and working directly with the scientists and engineers behind NASA's human spaceflight mission.
