Why we read it this way (5)
The required programming languages are listed as 'C++, Java, or Python' — the JD gates on proficiency in at least one of these, so all three are marked required with each other as alternatives rather than as three independent hard gates.
The title 'Software Engineer III' maps to a Senior-level individual contributor; the 6+ years experience requirement and scope (mentoring juniors, leading design, cross-functional collaboration) are consistent with Senior.
The clearance section references background check processes and U.S. person requirements (ITAR compliance) but does not explicitly gate on holding or obtaining a security clearance — marked None.
AI/ML is listed as a responsibility ('Build and integrate AI/ML-driven capabilities') rather than under a formal requirements heading, so it is treated as preferred context rather than a hard gate.
Preferred qualifications include RTOS/embedded systems, aerospace/defense background, additional languages (C, C#, HTML, Bash), software tooling (requirements tracking, static analysis, artifact repos, automated build), and Agile/Scrum methodologies — all listed under 'Qualifications We Prefer'.
