Why we read it this way (9)
No specific location is stated in the posting beyond 'onsite at a designated Lockheed Martin facility'; the CBSA/state could not be determined. The role is explicitly onsite full-time.
Degree requirement: the JD lists a Bachelor's in CS/engineering 'or equivalent experience', so no hard degree gate is set.
The top-secret clearance is a hard gate ('Active Top Secret security clearance required to start'). The posting also mentions a program-specific 'Whiskey program clearance' under Desired Skills, which is treated as preferred.
No overall years-of-experience floor is stated in the Basic Qualifications; the '3 years on the Whiskey program' appears only under Desired Skills and is program-specific, so it is not used as the overall years minimum.
Docker, Kubernetes, Helm, and Rancher are listed together as interchangeable containerization examples in the Basic Qualifications; Docker is used as the primary skill with the others as alternatives. Helm also appears separately under Desired Skills as an IaC tool, so it is additionally listed as a standalone preferred skill.
Jira and Confluence are listed together as Agile tooling examples; Jira is the primary with Confluence as an alternative.
The Lit framework appears under Desired Skills both as a general JS library example and as a specific front-end skill; it is captured as an alternative to React/Angular rather than a separate entry to avoid duplication.
HTML and CSS appear only under Desired Skills and are listed as separate skills given they are distinct technologies.
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.
