Why we read it this way (9)
The title 'Sr Principal' maps to advertised Principal; however, the actual scope and experience requirements (8 years, single-program security engineering) are consistent with a Senior-level role — Principal is reserved for org-wide technical authority.
The JD gates on an active Secret clearance at time of application, but also requires the ability to obtain Top Secret/SAP access — the hard gate at start is Secret, so the clearance requirement is set to Secret.
The DoD 8570 IAM Level II certification is required; CISSP and CAP are listed as examples of qualifying certifications, so they are captured as alternatives under one skill.
The 2-year minimum for anti-tamper or cyber-security risk-management activities is stated as a distinct sub-requirement within Basic Qualifications; the years demanded is set accordingly on that skill.
DOORS/Cameo/CPLM are listed as interchangeable requirements-management tools under Preferred Qualifications. JIRA, Confluence, and Fisheye are listed as collaboration platforms in the same preferred section.
The role blends systems security engineering (architecture, RMF, anti-tamper) with security analysis (threat modeling, pen testing, vulnerability analysis); 15-1212 is the best fit, with 15-1299 as a runner-up given the strong systems-engineering flavor.
This position is contingent upon contract award.
Ignored 2 non-technology phrase(s) as skills (responsibilities/concepts, not named tools): DoD 8570 IAM Level II, anti-tamper engineering.
Requires a Secret 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.
