Counts on this page come from AirTA's own daily checks of each company's careers page. When a number cannot be measured reliably, it is hidden rather than estimated. Industry describes the company, not the individual role, so an employer with several businesses appears under each industry it operates in. Report a data issue.

Counts are per-employer averages; shares are across all live postings on October 3, 2026. English rows use the English-level classification (a subset of postings), so they differ from the share of postings mentioning English in the Market Snapshot. A row is hidden when either side has too few postings to compare fairly.
