What this job asks for AI summary
A senior modeling and simulation systems engineering role supporting the Sentinel ICBM program in Roy, UT. The position centers on horizontal integration across multiple engineering disciplines — including flight analysis, targeting, structures, and aerodynamics — as well as coordination with other integrated product teams. The work involves cross-functional technical leadership, analysis coordination, and presenting complex engineering concepts to management. A background in aerospace or mechanical engineering and experience with simulation tools is expected.

Why we read it this way (7)
This is a Modeling & Simulation Systems Engineering role focused on aerospace/ICBM systems (Sentinel program). The primary day-to-day work involves M&S integration, systems engineering, and technical analysis across disciplines — it sits between a pure systems engineering occupation and a software/simulation developer role; 15-1299 (Computer Occupations, All Other) is used as the closest fit, with 15-1252 as a plausible alternative given the simulation/coding emphasis.
The title 'Sr. Principal' maps to Northrop Grumman's internal Level 4 designation; however, the actual scope (horizontal integration within a program team, 8+ years required) is consistent with a Senior-level role on a standard career ladder rather than a true org-wide Principal.
The clearance requirement is an active DoD Secret at time of application, with the additional need to obtain Special Access Program (SAP) approval — the Secret gate is the hard requirement captured here.
MATLAB, Python, and C++ are listed together as interchangeable options ('MATLAB, Python, C++, or similar') under Basic Qualifications; MATLAB is used as the primary name with Python and C++ in alternatives.
MBSE/CAMEO and MIL-STD-3022 experience appear under Preferred Qualifications.
The minimum experience requirement follows a tiered structure: 8 years with a Bachelor's, 6 with a Master's, or 4 with a PhD; 8 years is captured as the overall years minimum (the floor for the most common credential).
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.
