Why we read it this way (9)
The role blends hands-on kernel/OS engineering with container infrastructure design and some software development; it sits between 15-1252 (Software Developers) and 15-1244 (Systems Administrators). The primary day-to-day work — kernel customization, building and maintaining container infrastructure, automating OS builds, and contributing to codebases — tips it toward 15-1252, but the systems-administration and infrastructure-operations duties make 15-1244 a credible runner-up.
An active DoD Secret clearance is explicitly required at hire and must be maintained throughout employment.
The degree requirement accepts an Associate's, Bachelor's, or equivalent experience, so no formal degree is hard-gated.
Linux+ and Security+ certifications are explicitly listed as required qualifications.
Configuration management knowledge is called out as 'a plus' in the opening narrative and is marked preferred accordingly.
The posting names no specific container orchestration platform (e.g. Kubernetes, OpenShift), so well-known substitutes are listed as alternatives.
No compensation figures are provided in the posting.
Ignored 3 non-technology phrase(s) as skills (responsibilities/concepts, not named tools): container orchestration, OS automation, configuration management.
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.
