How this data is collected

AI Dev Jobs scrapes curated job feeds (Greenhouse, Ashby, Lever) from 538 ATS sources across 489 AI companies daily. Listings are filtered for AI/ML relevance; generalist roles are excluded. Salary figures come directly from the publicly posted compensation ranges on each listing — we do not estimate or impute. If a role doesn't publish a salary, it is excluded from these statistics but still appears in the job listings.

Data is refreshed every 24 hours. The percentile breakdowns above (p25, p50 median, p75) are computed over the midpoint of each published range. Experience level percentiles use the same midpoint method, grouped by the experience_level field on the listing. City-level figures require at least 3 open roles in that city for Jax.
