Why we read it this way (6)
The title reads 'O&M Systems Administrator' with no seniority level word, but the body explicitly states 'senior level Systems Administrator' — advertised seniority is treated as Unspecified (title-only) while the actual requirements support Senior.
The clearance requirement is stated as 'must be able to obtain and maintain' TS/SCI with poly — this is a hard gate even though the candidate need not currently hold it.
Red Hat Satellite is listed in the required section with the qualifier 'or other provisioning software'; alternatives are not named, so common peers (Foreman, Puppet) could substitute, but the provisioning capability itself is a hard gate.
The role is primarily Linux systems administration and operations (provisioning, configuration management, security compliance, end-user support) rather than software development, supporting 15-1244. The Bash/Ansible scripting component introduces some 15-1252 signal, hence the alt SOC.
HPC/supercomputing context (Lustre filesystem, RHEL/SE Linux) is noted as background; Lustre and NFS appear only under Desired Skills.
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.
