Why we read it this way (10)
The role is posted for two locations — King of Prussia, PA and Colorado Springs, CO. The Philadelphia CBSA is used as the primary metro; the Colorado Springs CBSA (17820) is a valid alternate location.
The title carries no seniority level word; 'Experienced Professional' is Lockheed Martin's internal career-level label, not a standard band, so the title states no level.
A Bachelor's degree is listed under Basic Qualifications but the posting explicitly states 'equivalent experience may be considered,' so the degree requirement is set to None.
Linux and Windows are listed as an 'and/or' gate in the Basic Qualifications; both are captured as a single interchangeable requirement.
The role blends cybersecurity engineering (RMF, hardening, vulnerability management) with DevSecOps pipeline work, making it a genuine hybrid between Information Security Analysts (15-1212) and a broader systems/software security engineering occupation (15-1299); 15-1212 is chosen as the primary because RMF, ATO, and security architecture are the dominant framing.
The posting is part-time remote (hybrid), not fully remote.
OCONUS deployment willingness is required per the posting — candidates should be aware this role involves potential international travel/deployment.
DoD 8570 IAT Level II certification (e.g., CISSP, CAP) appears under Desired Qualifications only.
Container scanning and IaC scanning are mentioned in the responsibilities narrative as pipeline integrations, not as standalone gated skills; they are subsumed under the SAST/DAST/DevSecOps gates rather than emitted separately.
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.
