Why we read it this way (9)
This is a Systems Engineering role, not a pure software/computer occupation — the closest SOC is 15-1299 (Computer Occupations, All Other) or 15-1211 (Computer Systems Analysts), but neither is a perfect fit; the role is fundamentally a defense/aerospace Systems Engineer. Confidence is Low as a result.
The title 'Principal Systems Engineer' at Northrop Grumman is a job-grade label (their internal level above Senior), not the 'Principal' band in the sense of org-wide technical authority; the actual scope and experience floor (5 years, STEM BS) maps to Senior.
Active DoD Secret clearance is a hard gate for start; the ability to obtain Top Secret is also required. Active Top Secret is listed under Preferred Qualifications.
The role requires the ability to obtain SAP/PAR access, which is stated as a hard requirement but is not a standard clearance tier captured in the clearance field.
DOORS is listed as an example tool ('tools such as DOORS') under a required 3-year experience block for Requirements Verification — the requirement is on the capability, but DOORS is the named tool and is marked required accordingly.
Cameo is listed as an example tool ('tools such as Cameo') under a required 2-year MBSE block — same treatment as DOORS above.
Prior Supplier Management experience, technical evaluation of supplier proposals, and experience creating/monitoring technical risks are listed under Preferred Qualifications.
Ignored 2 non-technology phrase(s) as skills (responsibilities/concepts, not named tools): Model Based Systems Engineering, configuration management.
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.
