Methodology

All figures come from salary ranges companies publish on their own job postings, pulled from their applicant tracking systems hourly. Nothing is self-reported or estimated.

Pay in other currencies is converted at fixed recent exchange rates. Hourly, weekly, and monthly pay is annualized. Everything is base salary only. Equity and bonus are excluded because postings rarely quantify them.

Stats are medians and quartiles of each posting's range midpoint, weighted by open roles. Groups with fewer than 30 openings (8 for a single company) are not shown.

Numbers reflect currently open roles, not historical offers. About 56% of tracked openings post pay. US pay-transparency laws drive most disclosure, so coverage skews to US roles. Explore hiring patterns in the hiring report.
