We read this from the posting text with AI. Skim the description below before ruling yourself out.
Why we read it this way (8)
All technical skills (Python, Bash, GitLab, Atlassian, SAST tools, Agile, object-oriented development) are listed under a 'preferred skills or experiences' section — none are hard gates.
The degree requirement is a hard gate: a Bachelor's in Software Engineering or a related STEM field is explicitly required. A Master's + 3 years is offered as an alternative path, but a Bachelor's + 5 years is the baseline.
An active DoD Secret clearance is required at time of hire — this is a firm gate, not merely preferred.
U.S. citizenship is required due to the nature of the work.
The role is fully on-site at the Dedham, MA facility (within the Boston metro CBSA).
The title carries no seniority level; the 5+ years requirement and scope (member of a cross-functional team, no explicit leadership mandate) support a Mid-level classification.
Ignored 1 non-technology phrase(s) as skills (responsibilities/concepts, not named tools): Object-oriented development.
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.
