An entry-level systems engineering role supporting the Navy's Fleet Ballistic Missile program, focused on developing environmental definition documentation and CAMEO-based models, writing requirements, and supporting verification and validation activities. The position suits early-career engineers with some familiarity with model-based systems engineering tools such as CAMEO or DOORS, and requires at minimum a Secret clearance with the ability to obtain Top Secret.

Why we read it this way (8)
The role is posted with two possible locations: Valley Forge, PA and Littleton, CO. Valley Forge (Philadelphia metro) is listed first; the Colorado location falls under the Denver-Aurora CBSA (19740). The salary range quoted explicitly covers Colorado among other states.
The Basic Qualifications gate on a Secret clearance with the ability to obtain and maintain a Top Secret. The Clearance Level header says 'Top Secret', but the hard gate in the requirements section is Secret — the clearance requirement is set to Secret accordingly. Active Top Secret is listed only under Desired Skills.
CAMEO and DOORS appear together in the Basic Qualifications as 'Knowledge or Familiarity in CAMEO or DOORs', making them interchangeable alternatives for the same hard-gate requirement. They are emitted as a single skill with alternatives rather than two separate entries.
Requirements writing also appears in Basic Qualifications as a hard gate ('Knowledge or familiarity in Requirements writing'). Despite the soft 'familiarity' phrasing, it is placed in the required qualifications block.
MBSE and systems engineering experience appear only under Desired Skills and are marked preferred.
The SOC classification is Medium-confidence: Systems Engineering in a defense/aerospace context sits closest to 15-1299 (Computer Occupations, All Other) given the model-based systems engineering (MBSE/CAMEO) focus, but 15-1211 (Computer Systems Analysts) is a reasonable runner-up.
Ignored 1 non-technology phrase(s) as skills (responsibilities/concepts, not named tools): systems engineering.
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.
