Why we read it this way (6)
The required programming languages are listed as 'C++, Java, or Python' — these are framed as interchangeable options for a single requirement. C++ is captured as the primary with Java and Python as alternatives. However, Java and Python also appear separately under the Preferred section with additional languages (C, C#, HTML, Bash), so they are also listed individually as preferred skills.
'Experience with agentic coding tools' appears in the hard-requirements block ('Qualifications You Must Have') but names no specific product. It is retained as a required skill since it is explicitly gated, though no canonical tool name could be assigned.
The degree requirement is a Bachelor's in CS, Software Engineering, or related field; the JD notes a 'higher level relevant degree may substitute for experience' but does not make the degree optional — equivalent experience is not offered as a substitute, so Bachelors is treated as the minimum hard requirement.
The Preferred section lists experience with 'software tools for requirements tracking, code reviews, static analysis, library and artifact repository, and automated build' — this names no specific tools and was omitted from the skills list per extraction rules.
An active Secret U.S. Security Clearance is explicitly required for employment.
Requires a 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.
