Why we read it this way (9)
This posting covers two levels simultaneously: Principal Systems Engineer (T-03, 5+ years with a Bachelor's, 2+ years DOORS/CAMEO) and Sr. Principal Systems Engineer (T-04, 8+ years with a Bachelor's, 4+ years DOORS/CAMEO). The overall years minimum and DOORS the years demanded reflect the lower T-03 gate; the upper T-04 salary ceiling ($184,200) is also captured in the top of the pay band.
The salary range spans both levels: $98,400–$147,600 for T-03 and $122,800–$184,200 for T-04.
An active Secret clearance is a hard gate at time of application. The ability to obtain Special Access Program (SAP) approval is also required. An active Top Secret clearance is listed under Preferred Qualifications only.
The role is primarily located in Roy, UT (Ogden-Clearfield CBSA), with an alternate location at Vandenberg AFB, CA. The CBSA reflects the primary listed location.
DOORS and CAMEO are listed as interchangeable alternatives within the same requirement ('2 years of experience with DOORS or CAMEO'); DOORS is used as the primary name with CAMEO in alternatives.
ICBM experience and an Aerospace/Systems/Mechanical/Software Engineering degree are listed under Preferred Qualifications and are not hard gates.
The advertised title includes both 'Principal' and 'Sr Principal'; the level advertised in the title is set to Principal as the higher of the two advertised levels. The actual scope and experience requirements (5–8 years, component/project ownership) align with Senior on the standard career ladder.
Ignored 1 non-technology phrase(s) as skills (responsibilities/concepts, not named tools): Systems 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.
