Why we read it this way (5)
All named technologies (Python, Bash, GitLab, SAST tools, Agile, Atlassian) appear under a 'preferred skills or experiences' framing — none are hard gates.
The only hard gates are the degree (Bachelor's in a STEM field, or Master's + 6 years), 8+ years of job-related experience, an active DoD Secret clearance at time of hire, and US citizenship.
The title carries no seniority level word; 'Unspecified' is used for advertised seniority. The 8+ years requirement and cross-functional technical leadership scope support a Senior classification.
The role is fully on-site at the Dedham, MA facility, which falls within the Boston-Cambridge-Newton CBSA.
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.
