What this job asks for AI summary
A systems engineering role supporting the Sentinel ICBM program, focused on logistics system capability. Day-to-day work involves managing requirements in DOORS, developing systems engineering governance documentation, collaborating with integrated product teams to mature weapon system design, and contributing to requirements development and model-based engineering processes. Suited to candidates with a background in DoD defense programs, particularly ICBM systems.

Why we read it this way (10)
This role is a Systems Engineering position in the defense/aerospace domain, not a pure software development role. SOC 15-1299 (Computer Occupations, All Other) is used as the closest fit; 15-1211 (Computer Systems Analysts) is a plausible alternative given the requirements analysis and modeling focus.
The posting covers two levels simultaneously: Principal Systems Engineer (T-03, 5+ years, $98,400–$147,600) and Sr. Principal Systems Engineer (T-04, 8+ years, $122,800–$184,200). The overall years minimum is set to 5 (the lower gate) and the full comp range spans both levels.
The level advertised in the title is set to Principal based on the primary title in the posting ('Principal Systems Engineer/Sr. Principal Systems Engineer'). The actual requirements support a Senior-level classification — 5–8 years of experience with component/program-level scope is typical Senior, not Staff or Principal on the engineering career ladder.
DOORS (Dynamic Object-Oriented Requirements System) experience is a hard gate at both levels (2+ years for Principal, 5+ years for Sr. Principal); the years demanded reflects the lower Principal-level gate.
Systems Engineering process governance documentation in a DoD EMD phase is a hard gate at both levels; captured as a required skill.
ICBM/complex aerospace-defense systems experience is a hard gate but names a domain rather than a concrete technology tool, so it is omitted from the skills list per extraction rules.
Agile, JIRA, Confluence, and DXL scripting appear only under 'Preferred Qualifications' and are marked accordingly.
An active U.S. Government DoD Secret clearance at time of application is explicitly required.
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.
