Senior Software Engineer

About Caribou

International tax is a rigged system where giant corporations funnel billions into the Big Four, offloading the burden onto smaller businesses.

Global SMEs face overpayments and fines because they lack the expertise to grok complex tax rules - the Big Four and other advisors profit from this chaos.

Caribou is a tax platform designed to make international tax accessible to every global business. We’re fixing Transfer Pricing first, where one million businesses are in need, but only ten thousand experts exist.

Our backers include Y Combinator, Accel, Lakestar and angel investors who were founders or executives of leading companies in London and SF.
