Why we read it this way (9)
Location is not explicitly stated in the posting, but the role is described as 'primarily onsite at the customer location' with limited telework — likely a cleared facility in the National Capital Region or a major intelligence community hub, but the specific CBSA cannot be confirmed from the text.
An active TS/SCI with Polygraph is a hard gate — candidates without it will not be considered.
The 'Hadoop or Cloud Developer certification' requirement is listed under the main Requirements section and is further clarified at the bottom: one of AWS Certified Developer – Associate, AWS DevOps Engineer – Professional, or CKAD is required and will be verified. This is treated as a hard gate; Hadoop is also listed as a standalone required skill reflecting the 'Hadoop or Cloud certification' phrasing.
The scripting language requirement (Python, Bash, Ruby, or Perl) is a hard gate on proficiency in at least one; Python is listed as the primary with the others as alternatives. Python also appears separately under Preferred Skills in the context of Spring Framework and Bash scripting — those preferred mentions do not change the required gate.
Bash appears both as an alternative to the required scripting language and in the Preferred Skills section alongside Spring Framework; it is captured as an alternative to the required scripting skill.
The 6-year Java requirement and 5-year Linux requirement are stated as minimums in the experience section and are treated as hard gates with the years demanded set accordingly.
C and C++ are mentioned as examples of high-level languages alongside Java in the experience requirement, but the Requirements section separately calls out 'Strong Java development experience' as the specific gate — Java is the named hard requirement; C/C++ are not separately gated.
AWS appears under Preferred Skills and is not a hard gate despite the cloud certification requirement.
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.
