Why we read it this way (7)
The Basic Qualifications state 'Must have Kubernetes or Linux' — these are listed as a disjunctive gate (either/or), so both are captured as required but with each as an alternative of the other. In practice the role clearly expects both, given the Essential Capabilities section.
The clearance gate is 'must be able to obtain' a Secret — not a requirement to hold an active clearance at hire, but it is a hard eligibility gate.
The role is a genuine hybrid between software integration/build engineering (15-1252) and systems/infrastructure administration (15-1244); the primary day-to-day work — integrating containerized software, automating builds, scripting — tips it toward Software Developers.
The Master's degree path (Master's + 6 months) is an alternative to the Bachelor's + 2 years path; Bachelor's is reported as the minimum formal degree since equivalent experience is not explicitly accepted in lieu of a degree.
Cyber hardening of Linux-based OS is listed as 'a plus' in the job summary narrative, so it is not captured as a required skill.
Red Hat System Administrator/Engineer certification appears under Desired Capabilities and is preferred only.
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.
