Why we read it this way (10)
The role is titled 'Tier 1 Systems Administrator' and is explicitly described as an early-career IT position, supporting the Junior seniority classification despite the wide posted salary range.
The clearance requirement is stated as an active Top Secret with the ability to obtain/maintain SCI — this is a TS/SCI gate.
Security+ (or equivalent DoDD 8140 451-Intermediate Matrix Qualification) is listed under required skills and treated as a hard gate.
Windows Active Directory and Red Hat Identity Manager (IdM) are listed as interchangeable alternatives for the same domain/identity management requirement.
A two- or four-year degree in Computer Science or related field is listed under 'Nice to Have' and is explicitly marked 'preferred', so the degree requirement is set to None.
Elastic (SIEM) is listed under 'Nice to Have' as the preferred SIEM tool; the broader SIEM experience is framed as preferred, not required.
Automation tools (Chef, Puppet, Ansible, Python, Bash) and hardware stack knowledge all appear under 'Nice to Have' and are marked preferred.
An Information Security Analyst (15-1212) runner-up is noted because the role includes assisting the security team with cyber reports and SIEM monitoring, though primary duties are clearly sysadmin.
Ignored 1 non-technology phrase(s) as skills (responsibilities/concepts, not named tools): Linux package management.
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.
