Why we read it this way (8)
This role is a mechanical/hardware Systems Integration Engineer for a missile defense program — it is not primarily a computer/mathematical occupation. No SOC code in the allowed list cleanly fits; 15-1299 (Computer Occupations, All Other) is used as the closest available code, with 15-1211 (Computer Systems Analysts) as a secondary option given the systems integration and test planning duties. A mechanical or aerospace engineering SOC (e.g., 17-2141) would be more accurate but is not available in the schema.
The job title carries no seniority level word; the title states no level. The desired skills mention '12+ years of experience in large program Configuration, assembly, and design integrations,' but this appears under the Desired (not Required) section, so it is not treated as a hard gate on total experience.
The clearance level listed in the body is 'Secret' (ability to obtain) under Basic Qualifications, but the formal 'Clearance Level' field at the bottom of the posting states 'Top Secret.' The higher stated clearance level (Top Secret) is used.
GD&T (Geometric Dimensioning and Tolerancing) is listed under Desired Skills and is therefore marked as preferred.
The salary range cited ($128,400–$226,435/year) applies specifically to California, Massachusetts, New York (excluding major metros), Colorado, Hawaii, Illinois, Maryland, Minnesota, New Jersey, Vermont, Washington, and Washington DC. The posting notes the range may differ for other states based on final work location.
Work location is onsite only; no remote option is offered.
Ignored 1 non-technology phrase(s) as skills (responsibilities/concepts, not named tools): Model Based Engineering.
Requires a Top 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.
