What this job asks for AI summary
An Information Systems Security Engineer role focused on designing and implementing security controls within software-based systems supporting government space communications infrastructure.

Why we read it this way (9)
The job location is not specified in the posting; Peraton is headquartered in Herndon, VA, but no city or site is stated. CBSA left blank.
The clearance gate is Secret (minimum required), with an expectation to upgrade to TS/SCI. Active TS/SCI is listed under Desired Qualifications, so it is marked preferred.
Degree requirement is set to None because the JD explicitly accepts equivalent work experience in lieu of a degree at every level (Associates + 10 yrs, BS + 8 yrs, MS + 6 yrs, PhD + 3 yrs, or 4 additional years in lieu of a bachelor's).
Total years minimum is set to 8, reflecting the lowest experience threshold tied to a bachelor's degree — the most common baseline. The Associates + 10 yrs path is also valid but represents a higher bar.
The role title is ISSE (Information Systems Security Engineer); the primary day-to-day work is applying security controls, compliance documentation, and security architecture — closest to Information Security Analysts (15-1212). Systems Analyst (15-1211) is noted as a runner-up given the systems engineering framing.
'Security documentation' covers control implementation statements, system security artifacts, and compliance evidence as described in the required qualifications; no specific platform or tool is named.
Linux and Windows are presented as an 'and/or' pair for the hardening/monitoring environment requirement — emitted as one skill with Windows as an alternative.
Ignored 4 non-technology phrase(s) as skills (responsibilities/concepts, not named tools): cybersecurity engineering, NIST SP 800-53, security control inheritance documentation, security documentation.
Requires a 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.
