Position Summary

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.

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

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 (TensorFlow, PyTorch) on HPC systems
Prior work on a DoD or Navy system administration contract, ideally in scientific or oceanographic computing
