Why we read it this way (6)

The posting lists four distinct work locations with different salary bands: Cambridge Crossing, MA ($151,280–$183,319); Madison/Giralda, NJ and Princeton, NJ ($137,530–$166,654); and Seattle, WA ($151,280–$183,319). The compensation range reported here spans the full cross-location minimum to maximum. The CBSA is set to Cambridge, MA (the first-listed location); hiring managers should note this role may be filled at any of the four sites.

The degree requirement states 'Bachelor's or higher degree … or a related field' but does not explicitly accept equivalent experience in lieu of a degree. However, the phrasing 'or higher' and the broad field list make this a soft gate in practice; the degree requirement is set to None because the JD does not hard-gate on a specific level.

Python/FastAPI and TypeScript/Node are listed together as a paired requirement ('Python and FastAPI and/or TypeScript/Node'); Python is treated as the primary must-have with TypeScript/Node as an alternative, reflecting the JD's 'and/or' framing.

AI coding agents (Claude Code, Codex, Cursor, Windsurf, GitHub Copilot, Gemini CLI) are explicitly required under the Required Qualifications section as a demonstrated ability, not merely preferred.

MCP servers, FastMCP, vector/graph/relational databases for retrieval, LangSmith/promptfoo, and multi-agent systems all appear exclusively under Desired Qualifications and are marked preferred accordingly.

The alternative occupation code 15-2051 (Data Scientists) is noted as a runner-up given the heavy ML/AI modeling and evaluation work described, but the primary day-to-day work is clearly software engineering — building and shipping cloud-native AI applications — making 15-1252 the clear primary.
