Why we read it this way (4)
The clearance requirement is nuanced: the JD states the candidate 'must be able to obtain and maintain a security clearance' (ability to obtain, not an active clearance), while noting 'Active MBI Clearance preferred.' Neither condition is a hard gate on holding an active clearance today, so the clearance requirement is set to None; however, US citizenship or Lawful Permanent Resident status is a hard requirement.
SOC classification is a genuine judgment call. The role is titled 'Senior System Engineer' and emphasizes infrastructure architecture, networking, virtualization, and security compliance — primarily operating and maintaining systems (15-1244). However, it also calls for DevSecOps automation and infrastructure provisioning work, which edges toward software development (15-1252). 15-1244 is chosen as the primary given the dominant infrastructure/operations framing.
AWS is listed first among the cloud platforms (AWS, Azure, GCP); all three are named together as a single interchangeable requirement, so Azure and GCP are captured as alternatives.
Scripting languages (PowerShell, Python, Bash) are listed together as a single proficiency requirement; PowerShell is used as the primary with Python and Bash as alternatives.
