About The Position

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. Why Intelliforce? Because you matter—your work, your growth, and your well-being. At Intelliforce, we don’t just push the boundaries of technology—we partner with some of the most mission-driven teams in defense and beyond to solve challenges that truly matter. As a Systems Engineer here, you won’t just contribute to projects—you’ll help shape outcomes that make a real-world impact. We also know that great work starts with a great environment. That’s why we invest in you:
