Why we read it this way (11)
The role requires the ability to obtain and maintain a Secret Security Clearance as a hard gate; an active Secret clearance is listed under Preferred Qualifications as a bonus.
The degree requirement is a Bachelor's in CS or a STEM field; a Master's degree reduces the experience floor from 8 to 6 years. The 8-year figure is used as the overall years minimum (the higher, more common path).
Source control/configuration management tools are required but no specific tool is named; Git is used as the canonical representative.
The Atlassian suite (Jira, Confluence) is listed under Preferred Qualifications; Jira is used as the primary skill name with Confluence in alternatives since they are co-listed as a suite.
Automated build processes (Bamboo, Jenkins) are listed under Preferred Qualifications; Jenkins is used as the primary name with Bamboo as an alternative.
Front-end development frameworks are listed as preferred alongside Java but no specific framework is named; no skill entry is emitted for the unnamed category.
Relational database experience is preferred; Oracle is used as the primary name with the other named options (MySQL, PostgreSQL, MariaDB, SQL Server) as alternatives.
TCP/IP, UDP, and DDS are listed together as interface communication standards under Preferred Qualifications; TCP/IP is the primary with UDP and DDS as alternatives since the posting treats them as a group of interchangeable protocol options.
Game theory, AI, petri nets, and safety-critical software are mentioned under Preferred Qualifications as domain knowledge concepts rather than named tools; no skill entries are emitted for these.
Up to 25% travel is required to support field testing and client engagements.
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.
