Advertised as Principal, but the requirements read as Mid.
“or” means any one of them counts — you don't need all of them.

Why we read it this way (6)
This posting covers two levels simultaneously: Systems Engineer (T-02, 2+ years) and Principal Systems Engineer (T-03, 5+ years). The advertised title includes 'Principal' but the minimum qualifications allow entry at 2 years of experience; seniority is assessed at the lower (Mid) gate. The salary range spans both levels ($79,300–$147,600).
This is primarily a hardware/systems engineering role (mechanical, electrical, aerospace systems for an ICBM re-entry payload) rather than a software or IT occupation. SOC 15-1299 is used as the closest available code; 15-1211 (Computer Systems Analysts) is the runner-up given the requirements analysis and MBSE/modeling work, but neither is a perfect fit for a defense systems engineer.
DOORS, Cameo, MagicDraw, UML, and SysML are listed under 'Experience with any of the following' — meaning the candidate needs experience with at least one of these tools, not all. They are grouped as a single interchangeable requirement at the T-02 level (required) and the same language repeats at T-03. MBSE tools (3 years) are a hard gate only at the T-03 level.
An active Secret clearance is a hard gate at time of application. The ability to obtain a Special Access Program (SAP) approval is also required but framed as obtainable within a reasonable period. An active Top Secret clearance and active SAP clearance appear only under Preferred Qualifications.
Preferred qualifications include 3 years of ICBM Weapon Systems experience, CDRL development, and system milestone experience (ARR, PDR, CDR) — these are listed under the explicit 'Preferred Qualifications' section and are not hard gates.
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.
