What this job asks for AI summary
This role supports space protection and defense programs through systems engineering technical assistance. Day-to-day work involves assessing architectures and requirements, conducting gap analyses, defining parameters for modeling and simulation efforts, and preparing technical briefings for senior government stakeholders. It suits a STEM-degreed engineer with a TS/SCI clearance and polygraph who has some familiarity with model-based systems engineering.
Mid level · 2+ years · Washington-Arlington-Alexandria, DC-VA-MD-WV · Bachelor's required · TS/SCI clearance
We read this from the posting text with AI. Skim the description below before ruling yourself out.
Why we read it this way (8)
This role is a space-systems / defense systems engineering position, not a conventional IT or software occupation. SOC 15-1299 (Computer Occupations, All Other) is used as the closest available code; 15-1211 (Computer Systems Analysts) is a plausible runner-up given the requirements analysis and enterprise architecture work, but neither code is a precise fit for a space-protection systems engineer.
TS/SCI with polygraph is an explicit hard gate listed under Required Skills/Qualifications.
A BS in a STEM engineering discipline is hard-required; an MS in the same is listed under Desired Skills/Qualifications.
MBSE is listed under Required Skills as a modeling familiarity requirement (ability to understand and provide feedback on models). SysML is explicitly called 'a plus' in the same sentence and is therefore preferred.
The role's 2+ years of experience requirement and scope (individual contributor supporting program offices) support a Mid-level classification despite the senior-stakeholder communication duties.
Prior SETA experience or supporting program offices is listed under Desired Skills/Qualifications only.
No compensation information is provided in the posting.
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.
