Python, Java, and Scala are listed together as interchangeable coding language options; Python is named first and is the most common in ML contexts, so it is the primary with the others as alternatives.
PyTorch and TensorFlow are listed as interchangeable framework options.
LLMs appear under both the responsibilities narrative and the Bonus/Plus Qualifications section; production LLM experience is listed as a bonus, so LLMs are marked preferred.
Spark and distributed training/real-time inference are cited under minimum qualifications with 'e.g.' framing, but they sit within a hard-requirements block and represent the class of capability required, so they are marked required.
