What this job asks for AI summary
This role administers the Model-Based Systems Engineering (MBSE) tool suite supporting requirements development for the Missile Defense Agency, primarily centered on IBM Rational DOORS. Day-to-day work involves access and configuration control, schema development, report generation, user training, and tool customization — including scripting in DXL, JavaScript, or VBA — to maintain the Technical Baseline for a complex system-of-systems defense program. Candidates should have a systems engineering background with hands-on DOORS administration experience and an active Secret clearance.

Why we read it this way (7)
The work location is listed as 'onsite at a designated Lockheed Martin facility' but no specific city or CBSA is named in the posting; the CBSA has been left blank.
The basic qualifications state '5+ years of hands-on experience performing software and/or systems integration and testing'; the desired skills section separately mentions '10 years of experience using and maintaining system engineering tools,' but that figure appears only under Desired Skills and is not a hard gate.
DXL is listed as a required skill (Basic Qualifications) alongside JavaScript and VBA as alternatives; the Desired Skills section also calls out DXL/VBA as a plus, which is consistent with DXL being the primary required scripting capability.
UNICOM System Architect, MagicDraw, and Cameo appear only under Desired Skills and are explicitly framed as a plus.
The posting is classified as a Task Order/IDIQ engagement type per Lockheed Martin's own labeling, but the standard employment type is not explicitly stated as contract vs. full-time; left as Unspecified.
SOC classification is Medium confidence: the role is primarily a tool administrator and systems engineering analyst (15-1211), but the scripting/customization duties and MBSE architecture work introduce some overlap with 15-1299 (Computer Occupations, All Other).
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.
