Every role here links straight to the employer's own careers page, and each row names the domain it will open. Roles that could only be linked through an aggregator are not listed: those links are restricted by country and break for anyone outside the posting's own, so they are counted in the market index but never shown as something to click.
Search covers the 20,000 most recently posted roles. Older postings still count toward the market index but are left out of search, because the whole searchable set is downloaded with this page and the full corpus would make that slow on a phone.
Salary shows only where the employer published it — roughly 99% of figures in the source are estimates and are excluded. Visa labels come from Department of Labor filings, not from job text.
