See related jobsEvery major NASA human spaceflight program - ISS, Orion, SLS, Commercial Crew, the Human Landing System, and Moon Base - runs analysis through the Flight Sciences Laboratory (FSL) at NASA's Johnson Space Center. That's 700+ machines, 26,000 cores, more than 10 petabytes of storage, and over 1,000 engineers and scientists who count on it every day. MRI Technologies supports NASA under the JETS II contract and is hiring an HPC Linux System Administrator to join the team that runs and improves this cluster. You'll administer the job scheduler and parallel filesystem, help users bring their own software environments into the cluster with HPC containers, build out CI/CD that runs on cluster run nodes (including Jacamar), and work side by side with the people behind NASA's human spaceflight mission. This is a hands-on, on-premises HPC role - not a public-cloud, DevOps-only, or Kubernetes-only position.
Based onsite at NASA Johnson Space Center in Houston, TX. Fully remote will be considered for the right candidate with strong, demonstrated HPC administration experience.
What We Are Looking For
Required - Core HPC Experience (Must Have)
- Hands-on, production experience ADMINISTERING an HPC job scheduler such as Slurm, PBS/Torque, or LSF (hard requirement). That means running the scheduler itself - partition/QOS configuration, accounting, node states, and troubleshooting failed or stuck jobs - not only submitting jobs to it.
- Hands-on, production experience ADMINISTERING a high-speed parallel filesystem such as Lustre or GPFS/Spectrum Scale (hard requirement). General NAS/SAN/NFS storage administration is not a substitute.
- Qualifying experience can come from any organization - a NASA center, a DOE or federal lab, a university/research computing center, another government agency, or private industry - and under any job title.
- At least 5 years of Linux system administration in on-premises, bare-metal, or cluster/research-computing environments, including at least 2 years of HPC administration. Cloud-only or DevOps-only backgrounds (for example, managing EC2/AKS/EKS without on-prem HPC cluster experience) do not meet this requirement.
Required - General
- Bachelor's degree or equivalent certification in a related field, typically with a minimum of 5 years of experience
- Experience using containers (e.g., Apptainer/Singularity, Podman) in an HPC setting - packaging and running user environments, including older OS or package versions, on a shared cluster rather than for traditional microservices
- Experience building and supporting CI/CD workflows, ideally ones that run on HPC clusters and run nodes
- Experience with system configuration management
- Experience with system monitoring and alerting
- Strong problem-solving, planning, and communication skills
- Works well in a collaborative team environment
- Must 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).
Preferences
- Experience with Red Hat-based Linux distributions (RHEL, Rocky, Alma)
- Familiarity with InfiniBand high-speed networking
- Experience with cluster provisioning tools such as xCAT or Warewulf
- Experience with Ansible and/or Foreman for configuration management
- Experience with log consolidation and monitoring tools, and with 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 nodes
- Experience applying AI in sysadmin work - for example, integrating AI tooling into operational workflows, automation, or user-facing HPC jobs
- MPI 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. Depending on your experience and business needs, we may consider candidates at any level for which the position is advertised.

Tips for Your Remote Linux Administrator Job Search
Apply early to remote roles that fit
Migrate Mate lists remote linux administrator openings from across the U.S. in one place, so you can find roles that match your stack and seniority level and apply directly without sorting through location-filtered listings.
Show async work in your portfolio
Remote employers want proof you document your work clearly. Publish runbooks, Ansible playbooks, or bash scripts on GitHub with detailed READMEs. Written documentation is treated as a core skill, not a bonus, in distributed linux admin teams.
Lead with remote infrastructure tools on your resume
Surface tools like Terraform, Ansible, Puppet, or Chef in your skills section and in job descriptions. Remote hiring managers scan for infrastructure-as-code experience because remote teams automate what co-located teams handle manually.
Prep for async-first remote interviews
Many remote linux administrator hiring processes include a written technical screen or a take-home config challenge before any live call. Practice explaining your troubleshooting process in writing, not just verbally, since that reflects how the job actually runs day-to-day.
Remote Linux Administrator Jobs: Frequently Asked Questions
How do I get a remote linux administrator job?
Target companies that run distributed engineering teams or operate fully remote, since those employers are built around async collaboration and trust self-directed administrators to work without in-person oversight. Remote hiring managers screen hard for written communication, comfort with infrastructure-as-code tools like Ansible or Terraform, and a demonstrated ability to troubleshoot independently. Certifications like RHCSA or CompTIA Linux+ strengthen your profile, and a home-lab GitHub repo showing real configurations gives you a concrete edge.
Which companies hire remote linux administrators?
Remote linux administrator roles are posted by QuadCode, Barnard College, and MRI Technologies and others right now, based on current remote listings on Migrate Mate as of November 2026. Remote-first software companies, cloud-native managed service providers, and distributed fintech and cybersecurity firms are among the most consistent hirers of linux administrators in fully remote roles.
Can you get a remote linux administrator job with no experience?
Yes, but remote entry-level linux administrator roles are harder to land because employers expect you to troubleshoot and escalate independently without a colleague nearby. Remote-first MSPs and cloud startups are your best targets, since they hire junior admins and invest in async onboarding. Substitute experience with a documented home lab, contributions to open-source Linux projects, and a RHCSA or CompTIA Linux+ certification to show you can operate without hand-holding.
Do you need a degree for remote linux administrator jobs?
Not always. Many remote employers care more about hands-on Linux skills and demonstrated results than a four-year degree, especially for mid-level and senior roles at cloud-native or remote-first companies. Certifications like RHCSA, LPIC-1, or CompTIA Linux+, combined with a portfolio of real configs, scripts, or home-lab documentation, often carry more weight than a CS degree in remote hiring decisions.
