Why we read it this way (6)

Multiple work locations are listed (Sunnyvale CA, New York NY, Seattle WA) with different salary bands; the compensation range shown ($168,100–$261,500/yr) reflects the Seattle floor and the Sunnyvale ceiling across all three locations.

The ML framework requirement lists JAX, PyTorch, vLLM, SGLang, Dynamo, TorchXLA, and TensorRT as a group under Basic Qualifications. These are presented as a collective knowledge requirement rather than strict alternatives; PyTorch is emitted separately as the most universally expected framework, with the others captured as alternatives on the JAX entry.

The 'Knowledge of Machine Learning and LLM fundamentals' requirement is a conceptual gate rather than a named tool; it is captured via the LLMs skill entry.

The preferred qualifications section mentions 5+ years of full SDLC experience and a Bachelor's degree in computer science or equivalent. The degree is listed only as preferred and explicitly allows equivalents, so the degree requirement is set to None.

Python is inferred as a likely primary language given the ML/infrastructure context and the ML frameworks listed, but no specific language is named in the JD; it is marked preferred accordingly.

Ignored 2 non-technology phrase(s) as skills (responsibilities/concepts, not named tools): software development, system design.
