Strong employer brand and mid-level title increase competition, but niche LLM/vector DB skills moderate applicant density.
Requires specialized LLM, vector DB, and production ML experience, making backgrounds less transferable across unrelated domains.
Explicit 4+ years requirement plus many mandatory LLM, vector DB, and production tooling requirements enforce strict filtering.
