  • GPU Operations: Trouble GPU-related performance issues at the driver, kernel, or firmware level and optimize configurations for training and inference workloads.
  • Infrastructure Automation: Build automation using Ansible, Terraform, and Python to eliminate manual provisioning, streamline patching processes, and enable scalable infrastructure operations.
  • Performance Monitoring: Monitor system performance, identify bottlenecks in compute/storage/networking layers, and proactively address reliability issues or capacity issues.
  • Cross-Team Collaboration: Work closely with network engineers, systems engineers, and SREs to ensure cohesive infrastructure operations and seamless integration with Kubernetes and platform orchestration layers.
  • Vendor Management: Serve as primary point of contact for hardware escalations, RMAs (Return Material Authorization), and vendor relationship for compute/storage/networking equipment.

Requirements

  • Experience: 5+ years in infrastructure engineering, systems engineering, or hardware-focused roles, preferably with AI/HPC workloads.
  • Linux Expertise: Strong background in Linux systems administration, performance tuning, and troubleshooting at the system level.  
  • Bare-Metal Provisioning: Hands-on experience with bare-metal provisioning tools (MAAS or similar) and automated deployment workflows.
  • DCIM & Documentation: Familiarity with data center infrastructure management tools (NetBox, Device42, or similar) for asset tracking, network documentation, and maintaining infrastructure source of truth.
  • Hardware & GPU Systems: Familiarity with server hardware, GPU configurations, drivers, and system level performance optimization.
  • Automation Skills: Proficiency with Ansible, Terraform, and scripting (Python, Bash) for infrastructure automation and operational efficiency.
  • Infrastructure Operations: Experience deploying and maintaining physical infrastructure in production data center environments.
  • Problem-Solving: Ability to troubleshoot complex hardware, firmware, and system issues under pressure.
  • Collaboration: Comfortable working with cross-functional teams including network engineers, systems engineers, and platform developers to resolve infrastructure challenges.

Preferred Qualifications

  • Experience with GPU workload orchestration platforms (Kubernetes, SLURM) and their infrastructure requirements.
  • Familiarity with high-performance networking (InfiniBand, RDMA, RoCE) and spine-leaf network architectures.
  • Experience with monitoring and observability tools (Prometheus, Grafana).
  • Understanding of Kubernetes infrastructure requirements (compute, storage, networking layer)
  • Exposure to co-located data center operations or building infrastructure for regulated environments
  • Background supporting research institutions, HPC facilities, or enterprise AI infrastructure

Key Technologies

  • Linux, Canonical MAAS, NetBox, Terraform, Ansible, Python, NVIDIA GPU Drivers/Tools, High-Performance Networking, Enterprise Storage Systems, Prometheus, Grafana

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
