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. What You'll Do 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, TensorFlow, 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 ## Related Videos - [Running Secure Life Science Research at Scale using Hybrid GPU HPC and Kubernetes 🧬](https://www.wearedevelopers.com/videos/100355-running-secure-life-science-research-at-scale-using-hybrid-gpu-hpc-and-kubernetes) - [Docker network without Docker](https://www.wearedevelopers.com/videos/1418-docker-network-without-docker) - [Shipping Faster with Less: Render on Cloud Hosting, AI Workloads, and the Future of DevOps](https://www.wearedevelopers.com/videos/1894-shipping-faster-with-less-render-on-cloud-hosting-ai-workloads-and-the-future-of-devops) - [Docker Compose: Rediscovered](https://www.wearedevelopers.com/videos/1978-docker-compose-rediscovered) - [Docker exec without Docker](https://www.wearedevelopers.com/videos/1094-docker-exec-without-docker) - [Docker build without Docker](https://www.wearedevelopers.com/videos/100114-docker-build-without-docker) ## Related Articles - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [Top 6 Hackathons for Developers in 2023](https://www.wearedevelopers.com/magazine/263-top-6-hackathons-for-developers-in-2023) - [Highest Paying Tech Companies for Developers](https://www.wearedevelopers.com/magazine/220-highest-paying-tech-companies-for-developers) - [Dev Digest 134 - Where pixels sing?](https://www.wearedevelopers.com/magazine/477-dev-digest-134-where-pixels-sing) - [7 Cloud Computing Trends Coming in 2025 for Developers](https://www.wearedevelopers.com/magazine/412-7-cloud-computing-trends-coming-in-2025-for-developers) - [9 Ways to Make Money Hacking](https://www.wearedevelopers.com/magazine/333-9-ways-to-make-money-hacking)
