Why we read it this way (7)
The posting requires a TS/SCI clearance WITH polygraph — this is a hard gate explicitly stated in the opening paragraph.
The experience requirement is stated as 'Bachelors Degree + 8 years' — the 8 years appears to be tied to the degree level (i.e., 8 years of relevant experience with a Bachelor's degree), which is a common federal contracting convention. This has been interpreted as a minimum of 8 total years of professional experience.
The role is located in Chantilly, VA (within the Washington DC metro CBSA). No remote option is indicated.
Skills are drawn from the required qualifications and responsibilities sections; the JD names no specific named tools beyond the generic 'COTS/GOTS' category, so no specific product names could be extracted.
The title 'ISSE' (Information System Security Engineer) carries no explicit seniority level, hence advertised seniority is Unspecified; however, the 8-year experience requirement and breadth of responsibilities support a Senior classification.
Ignored 5 non-technology phrase(s) as skills (responsibilities/concepts, not named tools): Information System Security Engineering, Network Engineering, security controls design, configuration management, COTS/GOTS security tools.
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.
