What this job asks for AI summary
A systems engineering role supporting an ICBM ground and airborne launch control program, focused on model-based systems engineering using tools such as Cameo Enterprise Architecture. Day-to-day work involves developing use cases, defining and allocating requirements, functional decomposition, interface definition, and verification and validation. The role suits STEM-educated engineers with hands-on MBSE experience and an active DoD Secret clearance.

Why we read it this way (9)
This posting covers two levels simultaneously: Systems Engineer Level 2 (Mid, 2+ years, salary $79,300–$118,900) and Principal Systems Engineer Level 3 (Senior, 5+ years, salary $98,400–$147,600). The compensation range shown spans both levels combined. Seniority and the overall years minimum are set to the lower (Level 2) gate as the entry point for the posting.
The role is classified as 15-1299 (Computer Occupations, All Other) because Model-Based Systems Engineering (MBSE) for defense/ICBM systems is a specialized systems engineering discipline that does not map cleanly to 15-1211 (Computer Systems Analysts) or 15-1252 (Software Developers); 15-1211 is the closest runner-up.
An active DoD Secret clearance (or higher) is a hard gate at time of application. The ability to obtain Special Access Program (SAP) approval is also required.
The domain experience requirement (C2, cybersecurity, NC3, communications, facility design, or military aerospace) is a hard gate for both levels but names no single specific technology — it is captured in the role context rather than as a named skill.
The 'requirements management' skill covers the stated requirement for experience with requirements management/analysis/allocations; DOORS is listed separately as a preferred tool under Preferred Qualifications.
MBSE tools (Cameo, Rhapsody, MagicDraw) are listed as interchangeable alternatives in the required qualifications; Cameo Enterprise Architecture also appears separately under Preferred Qualifications with a 3+ year threshold.
All skills under 'Preferred Qualifications' are marked preferred, including DOORS, SysML/UPDM, DoDAF/UAF, Cameo (3+ years), Python, Agile, and domain-specific experience items.
Ignored 3 non-technology phrase(s) as skills (responsibilities/concepts, not named tools): requirements management, systems architecture, Cameo Enterprise Architecture.
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.
