  • Operate and maintain distributed networking meshes across classified and unclassified domains
  • Implement and manage out-of-band management tools (IPMI, iDRAC, BMC, etc.) for remote troubleshooting and control
  • Integrate and optimize NVIDIA GPU infrastructure for AI/ML training and inference workloads
  • Collaborate with mission engineers, software teams, and government operators to ensure system readiness and performance
  • Provide on-site technical leadership for deployments, troubleshooting, and continuous improvement
  • Mentor junior engineers and establish operational best practices as the program scales
What You'll Bring
  • 3+ years of experience in site reliability, systems engineering, or hardware operations roles
  • Deep expertise with physical infrastructure: server racking, cabling, diagnostics, and troubleshooting
  • Strong Linux systems administration experience, including imaging and automated deployment
  • Hands-on experience managing large-scale clusters or distributed systems in OpenShift or Kubernetes
  • Familiarity with DevOps automation (Ansible, Terraform, CI/CD pipelines)
  • Experience configuring and managing networking and mesh architectures
  • Direct experience with NVIDIA GPUs, CUDA, and AI/ML frameworks
  • Proficiency with out-of-band management tools (IPMI/iDRAC)
  • Certifications: Linux+ and Security+ (required or in progress)
  • Excellent communication, documentation, and problem-solving skills
  • Clearance: Active TS/SCI required
Bonus Points
  • Experience operating in secure DoD or intelligence environments
  • Familiarity with Palantir platforms or other government data systems
  • Experience supporting AI/ML infrastructure in production or tactical settings
  • Experience tuning and monitoring HPC or GPU-accelerated clusters
