What this job asks for AI summary
A senior systems/software engineering role supporting geospatial data programs at the National Geospatial-Intelligence Agency, specifically the GeoData Cooperative and the GRiD initiative. Day-to-day work spans requirements engineering, cloud architecture, 3D/elevation data production workflows, and cross-organization integration across DoD and Intelligence Community systems. Best suited to an expert-level engineer with deep geospatial intelligence, systems engineering, and TS/SCI clearance credentials.
Senior level · Washington-Arlington-Alexandria, DC-VA-MD-WV · Master's required · TS/SCI clearance · Full-time
“or” means any one of them counts — you don't need all of them.

Why we read it this way (9)
This is a pipeline/contingent requisition — all positions depend on upcoming proposal opportunities or contract awards.
The role blends systems/requirements engineering with hands-on software engineering and geospatial data production; 15-1211 (Computer Systems Analysts) was chosen as the primary SOC because the dominant day-to-day work is requirements development, architecture analysis, and cross-program integration rather than shipping software. 15-1252 (Software Developers) is a credible runner-up given the explicit 'hands-on software engineering support' duty.
The JD requires a Master's degree OR 'equivalent Expert Level work experience as a System Engineer' — because equivalent experience is explicitly accepted, the degree requirement is set to Masters as the stated minimum formal credential, though the equivalency clause means it is not a strict hard gate for all candidates.
TS/SCI clearance is required; the JD also states candidates must 'pass a poly,' indicating a polygraph is expected.
Skills such as GDAL, PDAL, DoDAF, Enterprise/Solution/Data Architecture, LIDAR/IFSAR, DTED/GeoTIFF/NITF, and 3D data processing all appear under the 'Desired' section and are therefore preferred rather than required.
Several required skills (systems engineering, requirements engineering, cloud computing, GEOINT, DoD/IC knowledge) are domain competencies rather than named tools; they are included because the JD explicitly gates on them with 'Expert' language in the Required section.
No specific location is stated in the posting; Washington DC metro is inferred from the NGA/DoD/IC mission context and the nature of the work.
Ignored 3 non-technology phrase(s) as skills (responsibilities/concepts, not named tools): systems engineering, requirements engineering, Enterprise Architecture.
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.
