What this job asks for AI summary
A systems engineering role supporting complex defense and government programs across the full system lifecycle — from requirements analysis and functional decomposition through integration, verification, and delivery. The position centers on developing and maintaining MBSE models and SysML diagrams using Cameo, managing requirements in Jama, and producing key engineering documents such as ICDs, SRS, and SSS. Suited to an experienced systems engineer with a strong DoD background.

We read this from the posting text with AI. Skim the description below before ruling yourself out.
Why we read it this way (6)
The posting requires 12+ years of systems engineering experience, or 10+ years with a Master's degree; 12 is used as the minimum.
Clearance is stated as 'ability to obtain' rather than an active clearance already held — the role gates on US citizenship and clearance eligibility, not a current active clearance. Mapped to Secret as the minimum implied level for a DoD program; the actual required level is not explicitly named.
Jira and Confluence appear under Required Qualifications as 'familiarity with' — a softer gate than the firm requirements for Cameo and Jama, so treated as preferred.
Location is not explicitly stated in the posting; Leidos is headquartered in Reston, VA, and the role references US defense programs. The CBSA reflects that headquarters location as a best estimate.
The SOC code 15-1211 (Computer Systems Analysts) is used as the closest match for a Model-Based Systems Engineering / systems engineering lifecycle role; 15-1299 is noted as a runner-up given the specialized nature of the work.
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.
