A senior systems engineering role focused on model-based data architecture for the Sentinel ICBM ground system. The position leads a small team in developing and maintaining a configured data model across engineering tools, covering requirements definition, functional decomposition, interface definition, and verification and validation. It suits an experienced MBSE practitioner with a background in defense or command-and-control systems who can work with both technical teams and program stakeholders.

Why we read it this way (8)
The role is posted under four possible locations: Roy UT, Bellevue NE, Huntsville AL, and Manhattan Beach CA. The primary CBSA reported is Ogden-Clearfield, UT (Roy, UT), but the role may be filled at any of those sites.
The posting titles this a 'Sr. Principal Systems Engineer (level 4),' which maps to advertised Principal; however, the actual requirements (8 years with a BS, Secret clearance, 2+ years MBSE) are consistent with a Senior-level role on a standard career ladder.
The experience floor is stated as a tiered minimum: 8 years with a Bachelor's, 6 with a Master's, or 4 with a PhD — the 8-year figure is used as the overall years minimum.
The domain requirement (2+ years in C2, physical security, cybersecurity, NC3, communications, facility design, or military aerospace) is a hard gate but names a broad set of interchangeable domain areas rather than a specific named technology or tool, so it is not captured as a discrete skill.
An active DoD Top Secret clearance is listed under Preferred Qualifications; the hard gate is Secret. The posting also requires the ability to obtain SAP access, which is not a standard clearance tier.
Cameo Enterprise Architecture is explicitly named in the requirements section alongside Rhapsody and MagicDraw as acceptable alternatives ('such as Cameo, Rhapsody or MagicDraw'), so all three are captured under one skill entry.
Ignored 6 non-technology phrase(s) as skills (responsibilities/concepts, not named tools): requirements management, Cameo Enterprise Architecture, systems engineering Vee Model, Object-Oriented Systems Engineering Methodology, RAM-C engineering, Human Factors Engineering.
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.
