What this job asks for AI summary
A systems engineering role focused on hypersonic re-entry vehicle and advanced payload programs, centered on writing software functional requirements, interface control documents, and verification test plans. The work involves coordinating across mechanical, electrical, and software subsystem teams, leading requirements traceability, and supporting hardware-in-the-loop testing. It suits an experienced engineer comfortable with safety-critical standards and tools such as IBM DOORS or CAMEO.

Why we read it this way (10)
The job title is not explicitly stated in the posting; the role is classified based on its primary day-to-day work: systems/software requirements engineering, interface management, and verification planning — closer to Computer Systems Analysts (15-1211) than Software Developers (15-1252), though prior software development experience is listed as a preferred qualification.
The clearance requirement is stated as 'Active U.S. Government DoD Top Secret security clearance at time of application' in the Basic Qualifications, making it a hard gate. The posting header says 'Secret' but the body requires Top Secret — the body's explicit language governs.
The ability to obtain a Special Access Program (SAP) clearance is also listed as a Basic Qualification but is framed as an 'ability to obtain' rather than a current holding requirement.
IBM DOORS and CAMEO are listed together as interchangeable tool options ('such as IBM DOORS or CAMEO') for requirements traceability; they are captured as a single skill with alternatives.
CAMEO also appears separately under Preferred Qualifications in the MBSE context (alongside SysML and IBM Rhapsody), where it is clearly optional.
The experience requirement is stated as a tiered minimum: 8 years with a Bachelor's, 6 with a Master's, or 4 with a PhD — the overall years minimum is set to 8 (the minimum for the most common degree level).
The posting notes this position is contingent upon funding.
Nuclear surety/safety program experience and INCOSE CSEP certification are listed under Preferred Qualifications but name no specific technology or tool, so they are omitted from the skills list per extraction rules.
Ignored 1 non-technology phrase(s) as skills (responsibilities/concepts, not named tools): hardware-in-the-loop testing.
Requires a Top 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.
