Why we read it this way (9)
This is a Systems Engineering role in the aerospace/defense domain (Lockheed Martin Space, FBM Modernization and Sustainment Program). There is no single SOC code for Systems Engineers; 15-1299 (Computer Occupations, All Other) is used as the closest available fit, with 15-1211 (Computer Systems Analysts) as a reasonable alternative. Neither is a perfect match.
The title 'Senior Staff' is an internal Lockheed Martin level designation. The advertised seniority is mapped to Staff based on the title framing; however, the actual scope — leading a team of systems engineers and reporting to the Manager of Systems Engineering — supports a Senior band on a standard career ladder.
The Basic Qualifications gate on an 'Active DoD Secret clearance' with the 'ability to obtain a Top Secret clearance.' The Desired Skills section lists 'Active Top Secret Clearance' as preferred. The posting's Clearance Level field separately states 'Top Secret,' which is treated as the hard gate for this role.
No minimum total years of experience is explicitly stated in the posting.
A degree in Systems, Electrical, or Mechanical Engineering (or equivalent), INCOSE Certification, or relevant Graduate Certificate is listed under Desired Skills — not required. Equivalent experience is explicitly accepted, so the degree requirement is set to None.
JIRA, Agile, MBSE, DOORS, and Cameo all appear under the 'Desired Skills' section and are therefore preferred, not required.
The salary range quoted ($128,400–$226,435) applies specifically to Colorado (among other listed states); the posting notes the range may differ for other locations.
Ignored 5 non-technology phrase(s) as skills (responsibilities/concepts, not named tools): systems engineering, requirements development, ICD development, system integration and test, trade study methodology.
Requires a Top 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.
