Senior Specialist, Systems Engineer

The role is a classic Systems Engineering position — defining/decomposing requirements, architecture, CONOPS, V&V, trade studies, and design reviews — which maps most closely to 15-1211 (Computer Systems Analysts). 15-1299 (Computer Occupations, All Other) is noted as a runner-up given the defense/mission-systems flavor that doesn't fit neatly into any single SOC.

Degree requirement is marked None because the JD explicitly accepts 10 years of prior related experience in lieu of any degree.

The minimum experience threshold is 6 years (Bachelor's path); the graduate-degree path requires 4 years and the no-degree path requires 10 years — 6 years is used as the overall years minimum per the lowest qualifying combination with a degree.

An active TS/SCI with Polygraph clearance is a hard gate listed under Qualifications.

All named tools (Cameo/SysML, MBSE, INCOSE, Agile, lab test equipment) appear exclusively under 'Preferred Skillsets' or 'Preferred Qualifications' sections and are therefore preferred, not required.

Lab test equipment (oscilloscopes, spectrum analyzers, signal generators) are grouped as a single preferred skill with alternatives, as the JD lists them together as a single experience item.

Requires a TS/SCI 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.
