Advertised as Principal, but the requirements read as Senior.

Why we read it this way (7)
This requisition covers two levels: Principal Systems Engineer (Level 3, 5+ years with BS) and Sr. Principal Systems Engineer (Level 4, 8+ years with BS). The salary range spans both levels ($98,400–$147,600 for Level 3; $122,800–$184,200 for Level 4). The overall years minimum is set to 5 (the lower gate). The seniority is assessed as Senior — despite the 'Principal' title, this is a defense/aerospace engineering ladder where Level 3/4 Principal is equivalent to a Senior IC band; there is no evidence of org-wide technical authority.
The MBSE skill is listed with Cameo, MagicDraw, and Rhapsody as named interchangeable tools; the years demanded reflects the lower bound of the stated range (1–2 years for Level 3). For Level 4, the requirement rises to 2–4 years.
An active DoD Secret clearance is a hard gate at time of application. The posting also requires the ability to obtain Top Secret/SAP access, but does not require it to be held at start — the clearance requirement is set to Secret accordingly.
STEM bachelor's degree is required; a master's or PhD reduces the experience requirement but does not replace the degree gate.
Cameo, Confluence, and JIRA appear under Preferred Qualifications and are marked as preferred. Note that Cameo also appears in the required MBSE tools list as an interchangeable option — it is captured there as an alternative.
Ignored 1 non-technology phrase(s) as skills (responsibilities/concepts, not named tools): Systems architecture development.
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.
