Why we read it this way (10)
The role is titled 'Mid-Level Full Stack Software Engineer' and the Basic Qualifications gate on 4–8 years of experience with a Bachelor's (or 2–6 with a Master's). The degree requirement is treated as None because the JD explicitly accepts equivalent experience ('or related field') and the Master's path is an alternative, not a floor.
The primary work location is Gaithersburg, MD; the posting also lists Alexandria VA, Chantilly VA, Englewood CO, St. Louis MO, and Tucson AZ as permitted locations. The DC-metro CBSA is used as the primary metro since Gaithersburg is explicitly called the program's primary work location.
An active TS/SCI clearance plus the ability to pass a polygraph is a hard gate per the Basic Qualifications section.
The front-end/back-end frameworks requirement (React, Angular, Vue.js, jQuery, Spring Boot, Django, Node.js, Flask, Svelte) is listed as a single interchangeable group in the Basic Qualifications; React is used as the primary name with the others as alternatives.
Python/Java/JavaScript are listed as interchangeable OOP language options; Go is listed separately as 'Advanced Programming' and is treated as its own required skill.
JIRA and Confluence are listed together as agile collaboration tools in the Basic Qualifications; JIRA is the primary with Confluence as an alternative since they serve overlapping collaboration functions in this context.
Specific AWS services (S3, SQS, SNS, EC2, CloudFormation, RDS) appear only under Preferred Qualifications and are listed individually as preferred skills.
Geospatial tools (GeoServer, PostGIS, OGC APIs, ESRI ArcGIS) and Infrastructure-as-Code (Terraform, Ansible) appear only under Preferred Qualifications.
Certifications (AWS Certified Developer, Security+, SAFe Practitioner) are listed as preferred but are not concrete technologies or tools and are omitted from the skills list per extraction rules.
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.
