Senior System Administrator — High Performance Computing

Make an Impact Where It Matters Most

Intelliforce is looking for a hands-on system administrator who thrives in complex environments and takes pride in keeping mission systems performing at their best. In this role, you will support advanced compute infrastructure, including GPU-accelerated platforms powering analytics and AI workloads. This is a strong fit for someone who enjoys solving infrastructure problems, improving system performance, and supporting environments where uptime and reliability matter every day.

What Makes This Opportunity Stand Out

This role gives you the chance to work on infrastructure that supports some of the most demanding technical workloads in the mission space. You will help sustain and modernize high-performance environments, troubleshoot issues before they affect users, and support systems that continue to evolve as mission needs grow. The work is practical, visible, and closely tied to the success of the teams relying on these platforms.

At Intelliforce, your work is seen and your contribution matters. Because we support prime programs, our teams stay close to meaningful mission work with real momentum. Because we are a small business, leadership is accessible, communication is direct, and strong technical ownership gets noticed. Add in long-term stability, strong benefits, and a people-first culture, and this becomes more than another system administration role. It is a chance to support modern mission infrastructure where performance matters.

Here’s What Your Day-to-Day Could Include

  • Install and sustain hardware supporting mission compute environments
  • Tune system performance across Linux and GPU-accelerated platforms
  • Document configurations, procedures, and technical changes clearly
  • Coordinate with onsite teams to support operational needs
  • Troubleshoot issues across distributed environments before they impact users
  • Help modernize infrastructure to support evolving mission requirements

Minimum Qualifications

  • Clearance: Top Secret Clearance with Full Scope Polygraph, must be active. We do not have the ability to sponsor clearances
  • Citizenship: Must be a U.S. Citizen. We cannot sponsor visas
  • 9 or more years of system administration experience with or without a degree

Required Skills

  • Strong Linux administration experience
  • Experience supporting HPC or GPU-based systems
  • Hardware installation and sustainment
  • Troubleshooting distributed environments
  • Technical documentation skills

Desired Skills

  • Virtualization experience
  • Cloud exposure including AWS
  • Interest in AI and LLM infrastructure
  • Process improvement mindset

Compensation Range: $135,000.00 - $174,000.00

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.
