“or” means any one of them counts — you don't need all of them.
We read this from the posting text with AI. Skim the description below before ruling yourself out.
Why we read it this way (7)
The role is titled 'Model Based Systems Engineer' (MBSE) — a discipline that sits between systems analysis and software engineering. 15-1211 (Computer Systems Analysts) is the closest SOC match for MBSE work; 15-1299 (Computer Occupations, All Other) is a reasonable runner-up given how specialized the discipline is.
Cameo (or MagicDraw) appears in the Responsibilities section as the primary modeling tool ('primarily using Cameo'), making it a hard gate despite also being listed under Preferred Skills. MagicDraw is the same product family (No Magic/Dassault) and is listed as an interchangeable alternative.
SysML, Java/Python, and UAF all appear exclusively under the 'Preferred Skills and Experience' heading and are treated as preferred accordingly.
The posting states an Interim Secret clearance is required; candidates must be able to obtain one (US citizenship required). This is a hard gate.
The wide compensation range ($72K–$140K) reflects the posting's note that level is determined by experience, education, and clearance — no specific years of experience are stated at the role level.
The role is on-site in Fredericksburg, VA with weekly presence required at NSWC Dahlgren; telework opportunities are described as limited. The CBSA is mapped to the Washington-Arlington-Alexandria metro, which encompasses Fredericksburg/Stafford County.
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.
