Why we read it this way (7)
The 'Required Skills / Qualifications' section uses an unusual gating structure: candidates must satisfy at least 4 of 7 listed requirements. No single item is individually mandatory, but the section is framed as a hard gate overall. All 7 items have been marked required to reflect that they collectively form the qualification bar; hiring managers should note that any 4 of the 7 suffice.
AI coding assistants (e.g., Claude Code, Cursor, GitHub Copilot) and building AI skills/plugins/MCP servers/agents appear within the same required 7-item list, so they are captured as required under the same 'at least 4 of 7' logic.
InterSystems IRIS is listed as 'Familiarity with InterSystems IRIS, Caché, or Ensemble' — Caché and Ensemble are captured as alternatives since any one satisfies the requirement.
Windows and Unix are listed together as a single multi-OS requirement; Unix is captured as an alternative.
The Bachelor's degree and 4+ years of experience appear under 'Desired Experience,' not a hard-requirements block, so the degree is treated as not required and the overall years minimum is set to 4 (the minimum stated in the desired section — the only explicit overall experience figure in the posting).
The title says 'Senior Application Developer' but the requirements (4+ years desired, not required; 4-of-7 skill gate) support a Mid-level assessment. Advertised seniority is Senior per the title.
The role is headquartered in Boston, MA; no remote option is stated.
