HPC ​/ Linux Systems Administrator

Hpc/Linux Systems Administrator

VIRSIG is looking for an experienced HPC/Linux Systems Administrator to handle on site system administration, operational support, and cybersecurity compliance for a Hewlett Packard Enterprise (HPE) High-Performance Computing cluster supporting Artificial Intelligence (AI) and Machine Learning (ML) workloads at NAVOCEANO, Stennis Space Center, MS. This system is a strategic Navy asset built on GPU accelerated compute nodes, an HPE Slingshot high speed interconnect, a Lustre parallel file system, and image based OS deployment infrastructure.

If you enjoy solving complex technical challenges, working with cutting-edge HPC technologies, and supporting critical Department of Defense missions, we'd like to hear from you.

As the HPC / Linux Systems Administrator, you will:

• Install, configure, and maintain HPC components, including CPU/GPU compute nodes, the Slingshot interconnect, and the Lustre parallel file system
• Build and manage OS images for compute and service nodes so the software environment stays stable and consistent
• Manage user accounts, access controls, and resource allocation, and run the Slurm job scheduler
• Monitor system health and performance, handle routine maintenance and firmware updates, and coordinate hardware repairs with the vendor
• Keep system documentation current, including configuration details, troubleshooting steps, and security protocols
• Configure and manage the network, including switches, routers, and firewalls, and troubleshoot connectivity issues
• Manage HPC storage (Lustre, HPE Parallel File System, GPFS), including backups and capacity monitoring
• Install and maintain the HPC/AI-ML software stack (compilers, libraries, Tensor Flow, PyTorch, Docker, Singularity/Apptainer) and manage licenses
• Support users with performance tuning, GPU utilization, and getting the most out of the interconnect and file system
• Harden systems to DISA STIG requirements and support quarterly STIG compliance checks and remediation
• Run vulnerability scans and fix what they find, monitor security logs, respond to incidents, and help with A&A/ATO documentation
• Train NAVOCEANO staff through on the job instruction and documentation, and carry out a knowledge transfer plan so government staff can run the system independently by the end of the contract
• Help with monthly status reports, quarterly program reviews, and other NAVOCEANO briefings as needed

Required Qualifications

• U.S. citizen with an active DoD Top Secret clearance (Tier 5 investigation), adjudicated and in place before the contract start date
• Meets the OPM qualification standard for IT Specialist (2210) or Computer Scientist (1550) at the GS-12 level or above, roughly 4 years of specialized IT/network administration experience
• Bachelor's degree in Computer Science, or a bachelor's degree with 30 semester hours in math, statistics, and computer science (at least 15 of those hours in calculus or statistics), or equivalent experience
• Hands on experience running Linux in an HPC environment
• Experience with parallel file systems (Lustre), GPU accelerated compute nodes, and high speed interconnects (HPE Slingshot)
• Experience with job schedulers (Slurm) and containers (Docker, Singularity/Apptainer)
• Familiarity with DISA STIGs, vulnerability management, and DoD security frameworks (NIST 800-53, DoD Risk Management Framework)
• Solid written and verbal communication skills, comfortable writing training materials and teaching government staff

Preferred Qualifications

• Experience with HPE Cray System Management or HPE Performance Cluster Manager
• Experience supporting AI/ML frameworks (Tensor Flow, PyTorch) on HPC systems
• Prior work on a DoD or Navy system administration contract, ideally in scientific or oceanographic computing
• DoD 8570/8140 IA Technical Level I certification, or willingness to get it soon after hire

Work Environment

• Full-time, on-site position located at NAVOCEANO, Stennis Space Center, Mississippi
• Monday through Friday, 7:00 AM – 4:30 PM, aligned with the Government work schedule
• Must maintain required security clearance and Common Access Card (CAC)
• Must complete all required Government security, OPSEC, and anti-terrorism…
