What this job asks for AI summary
A systems engineering role centered on Model-Based Systems Engineering, building and maintaining system architecture models in Cameo (SysML) while keeping requirements in IBM DOORS consistently traced to those models. Day-to-day work spans structural and behavioral modeling, bidirectional traceability, supporting design reviews, and collaborating with systems, software, and hardware teams. Suited to engineers with hands-on MBSE tooling experience, ideally in aerospace or defense programs.

Estimated from BLS employment for this occupation and area, per-skill prevalence across our listing corpus, and published wage benchmarks — as of Jul 28, 2026. It is a model, not a headcount.
Why we read it this way (6)
This role is posted at two levels: Level 3 (Principal Systems Engineer, $98,400–$147,600/yr, min 5 yrs BS or 3 yrs MS) and Level 4 (Sr. Principal Systems Engineer, $122,800–$184,200/yr, min 8 yrs BS or 6 yrs MS). The compensation range shown spans both levels. The overall years minimum is set to 5 (the lower gate for Level 3).
Clearance: no active clearance is required at start, but candidates must be US citizens and able to obtain a DoD Secret clearance — treated as a Secret gate.
SOC classification is Medium confidence: the role is a specialized Systems Engineer focused on MBSE modeling and requirements management rather than general IT systems analysis, but 15-1211 (Computer Systems Analysts) is the closest standard code; 15-1299 is noted as an alternative.
'Requirements traceability' is listed as a required skill because the JD explicitly gates on demonstrated experience establishing and maintaining traceability — it is a core, named competency of the role, not a generic soft skill.
Preferred qualifications include aerospace/defense domain experience, SysML patterns, Cameo–DOORS integration (OSLC, data sync), and MBSE leadership/SME experience — all listed under the Preferred Qualifications section.
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.
