ML Engineer vs Principal Engineer: which pays more?
The median for ML Engineer is $205,841 per year (typically $175,000–$250,750), versus $223,250 for Principal Engineer ($187,500–$275,639). That puts Principal Engineer about 8% ahead at the median.
Both figures are computed live from active listings on JobsRadar and normalized to annualized USD, so ML Engineer and Principal Engineer are compared on equal terms regardless of the currency each role was originally posted in. Only roles that publish a salary range feed the medians; numbers refresh every few hours as new roles post and older ones close, so this comparison reflects the market right now rather than a fixed survey. Use it as a directional benchmark when weighing one path against the other.
