Why we read it this way (9)
The role is a genuine hybrid between Linux/systems administration (O&M, security hardening, incident response, multi-site infrastructure) and DevOps/software engineering (CI/CD pipelines, IaC, automation code). It was classified as 15-1244 because the primary framing is operating and maintaining enterprise Linux infrastructure across classified networks; 15-1252 is the close runner-up given the significant automation and DevOps engineering scope.
Experience requirement varies by degree: 12 yrs (BS/BA), 10 yrs (MS/MA), 7 yrs (PhD), 16 yrs (HS diploma). The overall years minimum is set to 10 (the most common graduate-degree threshold); the actual gate depends on the candidate's education level.
No work location or CBSA is specified in the posting. The role references 'multiple sites and classified networks,' suggesting an on-site or multi-site requirement; remote=false is set accordingly.
GitLab and Jenkins are listed together as examples of a DevOps toolchain ('GitLab, Jenkins, Ansible, or equivalent'); they are treated as alternatives for the same toolchain requirement rather than separate mandatory skills.
Ansible appears both as part of the DevOps toolchain and as an IaC tool; it is captured once as a required skill.
CloudFormation and Ansible are listed as examples of IaC tools ('CloudFormation, Ansible, or equivalent'); CloudFormation is captured as the primary with common alternatives noted.
AWS C2S is listed under Preferred as a distinct classified-cloud environment; it is grouped with GovCloud under the preferred AWS GovCloud skill.
The degree requirement is set to None because the JD accepts equivalent years of experience in lieu of any specific degree (HS diploma + 16 years is an explicit path).
Requires a TS/SCI 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.
