Why we read it this way (10)
The role title is 'Systems Administrator' but the posting is set in a cyber/DoD context with security-adjacent duties (STIG/SCAP hardening, ACAS, Splunk, SolarWinds). Primary day-to-day work is operating and maintaining infrastructure (servers, VMs, AD, storage, patching), which maps to 15-1244; 15-1212 is the runner-up given the security mission framing.
Clearance requirement is 'Active TS clearance, SCI eligible' — this is a Top Secret clearance with SCI eligibility, not a full TS/SCI adjudication; classified as TopSecret accordingly.
Education requirement accepts a Bachelor's + 5 years, Master's + 3 years, PhD + 0 years, or 4 years of additional relevant experience in lieu of a Bachelor's — no single degree is a hard gate, so the degree requirement is set to None.
The 5-year minimum (Bachelor's path) is used as the overall years minimum; the Master's path (3 years) is a lower-floor alternative.
FITSP-O and GFACT are listed under Desired Certifications but are niche/less-common credentials; they are omitted from the skills list as they are not widely recognized canonical tool/technology names.
Disaster recovery planning is listed under Desired Qualifications but names no specific tool, so it is omitted per the generic-concept rule.
Backup technologies are mentioned in Required Experience with only 'familiarity' language and no specific product named; omitted as no canonical tool is identified.
Ansible and Terraform appear together under 'CI/CD automation (Ansible/Terraform)' in Desired Qualifications — emitted as a single preferred skill with Terraform as an alternative, reflecting the interchangeable framing.
Azure and AWS appear together under 'Cloud services (Azure/AWS)' in Desired Qualifications — emitted as a single preferred skill with AWS as an alternative.
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.
