Why we read it this way (8)
The title 'Systems Engineer III' maps to a Senior-level role (III = Senior on a standard career ladder), consistent with the 6+ years requirement and the expectation to lead and mentor junior engineers.
SOC 15-1299 (Computer Occupations, All Other) is used because Systems Engineering in an aerospace/defense context — spanning requirements management, V&V, MBSE, and architecture — does not map cleanly to any single listed SOC. 15-1211 (Computer Systems Analysts) is the closest runner-up given the requirements analysis and integration focus.
The clearance notice references ITAR/export-control citizenship requirements and links to DCSA background check information, but no specific clearance level is stated as a hard gate for this role.
DOORS and Cameo are listed together under the preferred section as examples of requirements management and system modelling tools; they are captured as alternatives of one another. MATLAB is listed separately in the same preferred section.
INCOSE certification (ASEP/CSEP) is listed under preferred qualifications and is treated accordingly.
Agile methodologies and Scrum Master certification appear only under preferred qualifications.
The degree requirement is a hard gate (Bachelor's in Systems Engineering, EE, ME, or related field), though a higher-level degree may substitute for some experience.
Ignored 2 non-technology phrase(s) as skills (responsibilities/concepts, not named tools): requirements engineering, systems modeling and simulation.
