Why we read it this way (9)
SOC classification is Medium confidence: the role is primarily an IT/network systems administration and operations role (15-1244), but the significant emphasis on security operations — Defender, Sentinel, Conditional Access, CMMC/NIST 800-171, CUI handling, and security posture improvement — makes 15-1212 (Information Security Analysts) a credible runner-up.
The posting is explicitly part-time ('part-time Senior IT & Network Systems Administrator'), which is unusual for a senior-level role at this salary range; the $95K–$130K figure may be prorated or represent a full-time equivalent — the posting does not clarify.
Juniper/JunOS appears in both the 'What you'll do' section and the Preferred Qualifications section. Because it is not listed under Required Qualifications, it is treated as preferred.
PowerShell, Python, and JavaScript appear in both the responsibilities narrative and the Preferred Qualifications section; they are not listed under Required Qualifications, so they are treated as preferred.
CMMC and NIST SP 800-171 appear in both the responsibilities narrative and Preferred Qualifications; they are not listed under Required Qualifications and are treated as preferred.
No degree requirement is stated anywhere in the posting.
No security clearance is explicitly required; the role supports a government contractor environment but the JD does not gate on holding or obtaining a clearance.
Ignored 1 non-technology phrase(s) as skills (responsibilities/concepts, not named tools): NIST SP 800-171.
Posting is for a part-time engagement — the market benchmarks below price full-time roles, so read the comp comparison with that in mind.
