Why we read it this way (8)
This role sits at the intersection of systems engineering, electrical engineering, and software development — a genuine hybrid. 15-1299 (Computer Occupations, All Other) is used because the primary day-to-day work spans hardware/software prototyping, RF/communications systems, and custom tool development in a way that doesn't cleanly map to a single standard SOC; 15-1252 (Software Developers) is the closest runner-up given the coding and prototype development duties.
The posting requires an active TS/SCI with CI Polygraph — this is a hard gate explicitly listed under Minimum Requirements.
The minimum experience thresholds are 5 years each in systems engineering, software development support, and electrical engineering. The preferred qualifications raise these to 10 and 8 years respectively; only the minimums are treated as gates.
A degree in systems or electrical engineering appears only under Preferred Qualifications, so no minimum degree is hard-required.
UHF/HF/ELF frequency spectrum and encrypted communications experience is listed as a single requirement covering multiple RF bands; captured as one skill reflecting the combined RF/communications domain knowledge.
C4I/C5ISRT mission experience (military or contractor/government) is listed as a hard requirement under Minimum Requirements.
Ignored 1 non-technology phrase(s) as skills (responsibilities/concepts, not named tools): UHF/HF/ELF communications.
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.
