Why we read it this way (8)
The role blends Linux systems administration/configuration with integration and test work, making it a genuine toss-up between 15-1244 (Network and Computer Systems Administrators) and 15-1253 (Software Quality Assurance Analysts and Testers). The primary day-to-day emphasis on configuring, maintaining, and operating Linux environments — including patch management, virtualization, and deployment — tips the classification toward 15-1244, with 15-1253 as the runner-up given the explicit integration and test/validation duties.
Degree requirement: a Master's + 6 years OR a Bachelor's + 8 years OR equivalent experience + 8 years are all accepted paths, so no hard degree floor is set.
The 8-year minimum (Bachelor's path, the most common) is used for total experience; the Master's path requires 6 years.
PitBull (a mandatory access control Linux OS) and Satellite (Red Hat Satellite) appear only in the 'What Sets You Apart' preferred section alongside Ansible Tower/AAP.
STIGs (Security Technical Implementation Guides) appear in the 'What Sets You Apart' preferred section.
IAT Level II certification (CompTIA Security+, GSEC, SSCP, or CCNA-Security) is explicitly required at time of hire; the alternatives are listed as acceptable equivalents per DoD 8570/8140.01.
TS/SCI clearance is a hard gate — required at time of hire, not merely preferred or obtainable.
Requires a TS/SCI clearance — the cleared population is a small fraction of this occupation, so the real candidate pool is materially smaller than the estimate below, which does not model clearance.
