Why we read it this way (10)
The role is titled 'Software Engineer Level 3'; 'Level 3' maps to a senior individual-contributor band, consistent with the 15-year experience requirement.
A TS/SCI clearance with a Maryland Polygraph is an explicit hard gate; no interim or CCA clearances are accepted.
A Bachelor's degree in Computer Science or a related field is required, but 4 years of additional SWE experience (19 total) may be substituted — the degree requirement is set to None to reflect that equivalent experience is accepted.
The 15-year overall SWE experience requirement is the primary gate; it is stated at the role level, not tied to any specific technology.
Python and Shell scripting are listed in the Required Skills section alongside C++ ('C++ and some Python and Shell scripting experience'), so all three are treated as hard gates despite the softer 'some' qualifier on Python/Shell.
SDR (Software Defined Radio) familiarity is listed as a required skill but framed with 'Familiar with', suggesting a lower bar; it is marked preferred accordingly.
The role blends broad software development responsibilities with a specific emphasis on test engineering, build modernization, and continuous testing — the alt SOC 15-1253 (Software QA Analysts and Testers) is a genuine runner-up given the explicit 'Software Test Developer Engineer Expertise' requirement.
No compensation figures are provided in the posting.
Ignored 1 non-technology phrase(s) as skills (responsibilities/concepts, not named tools): software test development.
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.
