About the role

** System Administrator, STE Mission Support **

At Intelliforce, we support mission environments where uptime, performance, and technical precision matter every day. In this role, you will help keep critical STE systems stable, secure, and ready to perform. You will work across Linux administration, network troubleshooting, storage support, and containerized environments to strengthen the infrastructure mission teams rely on.

This role is a strong fit for someone who likes being hands-on in the environment, solving real infrastructure problems, and keeping systems moving without unnecessary drama. You will work across Linux systems, Cisco networking, NetApp storage, and Kubernetes-based environments, which means the work stays technical, practical, and varied. Your impact will be easy to see because the systems you support are directly tied to mission execution. At Intelliforce, your work is visible and your contributions matter. 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.
