Why we read it this way (7)
The job title carries no seniority level, so advertised seniority is Unspecified; however, the 10+ years of experience requirement and responsibilities (mentoring junior engineers, leading strategic projects, driving continuous improvement) support a Senior classification.
The required programming language is framed as 'C++, Java, or Python' — these are listed as interchangeable options under the required qualifications. C++ is captured as the primary with Java and Python as alternatives.
Agentic coding tools is listed as a required qualification but is a novel/emerging category with no single canonical product name; it is retained as stated since no specific tool is named.
The preferred languages (C, C#, HTML, Bash) are listed under 'Qualifications We Prefer' and are marked accordingly. Java and Python also appear there, but they are already captured as required alternatives above.
Agile/Scrum, Waterfall, and Spiral are listed under preferred qualifications as methodology knowledge; Agile is the primary with the others as alternatives since they are presented as interchangeable methodology options.
An active/current Secret clearance is explicitly required and repeated twice in the posting as a hard gate.
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.
