What this job asks for AI summary
A systems engineering role supporting ground-based hardware assemblies for an ICBM program. Day-to-day work centers on decomposing and flowing down requirements, developing verification methods, and producing model-based systems engineering artifacts using DOORS and Cameo. The role suits a STEM-degreed engineer with hands-on MBSE experience who holds an active DoD Secret clearance.

Why we read it this way (7)
This is a Systems Engineering role in the defense/aerospace domain — not a pure software or IT occupation. 15-1299 (Computer Occupations, All Other) is used as the closest available code; 15-1211 (Computer Systems Analysts) is a plausible runner-up given the requirements-analysis and systems-definition work, but neither is a perfect fit for a hardware-integration systems engineer.
The posting covers two levels simultaneously: Principal Systems Engineer (Level 3, 5+ years with a bachelor's) and Sr. Principal Systems Engineer (Level 4, 8+ years with a bachelor's). The seniority is assessed as Senior — the scope is component/product-level ownership within an IPT, which is characteristic of a Senior engineer despite the 'Principal' title used by Northrop Grumman's internal ladder.
Salary range spans both levels: $98,400–$147,600 (Level 3) and $122,800–$184,200 (Level 4). The combined range is reported here.
The role is located in Roy, UT or Manhattan Beach, CA. Roy, UT falls within the Ogden-Clearfield CBSA; Manhattan Beach, CA falls within the Los Angeles-Long Beach-Anaheim CBSA. Roy, UT is listed first and is the primary location for the Sentinel ICBM program.
Years demanded for MBSE, DOORS, and Cameo are set to 1 (the minimum stated for the lower Level 3 band). The Level 4 band requires 2–4 years for each.
An active DoD Secret clearance is a hard gate at time of application. The ability to obtain Special Access (SAP) is also required but is framed as achievable within a reasonable period rather than required at start.
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.
