Job Analysis:

The Principal System Administrator (Linux) role is fundamentally designed to ensure the reliability, security, and performance of classified IT infrastructures within a high-stakes government and defense environment. This position demands deep expertise in Linux system administration integrated with Windows server knowledge, reflecting the heterogeneous environments common in advanced military and aerospace IT ecosystems. The candidate is expected to solve complex technical challenges around server configuration, network services such as DNS and DHCP, cybersecurity compliance, and enterprise backup solutions. Given the classified nature of the systems, maintaining rigorous security protocols and working closely with cybersecurity teams is critical, as is meticulous documentation and training to support continuous operational readiness. The role requires a balance of technical autonomy and collaborative problem-solving in a dynamic setting where decisions impact mission-critical programs and classified data integrity. Success in the first 6–12 months will involve establishing secure, stable environments, streamlining administration processes, quickly troubleshooting complex issues, and achieving mandated DoD certifications like CompTIA Security+ to align with regulatory compliance. The requirement for a Top Secret clearance and possible TS/SCI eligibility underlines the sensitivity and importance of the role within the national security framework, adding a layer of unique operational and ethical responsibility for the candidate.
