Linux Systems Administrator (RHEL / VMware) –Huntsville

ALTECH SOLUTIONS, LLC•Huntsville, AL

1d•$80,000 - $88,000•Onsite

About The Position

Altech Solutions is hiring a Linux Systems Administrator to support NASA enterprise IT and aerospace infrastructure at Marshall Space Flight Center in Huntsville, Alabama. This is a hands-on, on-site role for someone who runs RHEL every day and wants that work pointed at NASA mission systems. You will keep the Linux environment behind NASA operational systems healthy: installing and configuring servers, patching and hardening, tuning performance, managing storage and file systems, automating the repetitive parts, and troubleshooting problems to root cause. Much of that environment runs virtualized, so VMware experience is a real advantage here — not required to apply, but it will move you up the list. You will work alongside database administrators, network engineers, application teams, and NASA customers.

Requirements

Bachelor's degree in Computer Science, Systems Engineering, Information Technology, or a related technical field
6 years of professional Linux systems administration or IT infrastructure experience
Strong hands-on Red Hat Enterprise Linux administration — installation, configuration, patching, and troubleshooting
Shell scripting and command-line proficiency; Python or similar a plus
Working knowledge of storage and file systems — LVM, NFS, partitions, disk provisioning
Understanding of networking fundamentals and IT security best practices
Experience with system backups and recovery
Self-directed, with strong documentation and communication skills
U.S. Citizenship with the ability to obtain and maintain a Public Trust clearance or higher
Residence within 50 miles of NASA Marshall Space Flight Center, Huntsville, AL

Nice To Haves

VMware vSphere and ESXi experience — the strongest differentiator for this role after Linux itself
Active Public Trust clearance (or an active Secret or higher)
Red Hat certification — RHCSA or RHCE
CompTIA Security+ or Linux+
Direct experience supporting government, aerospace, or NASA mission-critical environments
DISA STIG hardening, SCAP, or OpenSCAP compliance experience
Configuration management and automation — Ansible, Puppet, or similar
Windows Server administration alongside Linux
Enterprise storage — SAN or NAS, RAID, LUN presentation
Kickstart, Red Hat Satellite, or other automated provisioning tooling
Familiarity with containers — Podman, Docker, or OpenShift

Responsibilities

Install, configure, and maintain Red Hat Enterprise Linux servers — physical and virtual — in support of NASA operational requirements.
Perform patching, updates, and security hardening, including STIG compliance and vulnerability remediation.
Monitor system health and performance; tune systems for optimum performance and resolve faults before they reach users.
Manage storage and file systems — LVM, partitions, NFS, and disk provisioning — and support backup and recovery operations.
Write and maintain shell or Python scripts, and use configuration management tooling, to automate routine administration.
Manage user accounts, groups, permissions, and access controls, including directory integration.
Support the virtual infrastructure the Linux estate runs on — provisioning, patching, and troubleshooting Linux virtual machines, and working with vSphere and ESXi alongside the team.
Troubleshoot system, service, storage, and network issues to root cause, and document the resolution.
Develop and maintain system documentation, build records, and standard operating procedures.
Track and resolve issues through the ticketing system, and support scheduled maintenance and change management.
