We believe the world needs a place where people can exchange their loved goods. That’s why we built Mercari—to connect people who want to buy and sell things of emotional value through their mobile phones. Mercari has grown to become a leading community-powered marketplace in Japan that brings together millions of people every day.
▼About this position
Mercari's Backend Team is currently entering a major transition phase as part of the company's efforts to fulfill our mission of "creating value in a global marketplace where anyone can buy & sell.” The Mercari app has been growing at an incredible pace ever since its release and is now the largest C2C platform in Japan. The Mercari API codebase has also expanded in line with the service's growth and the variety of challenges faced.

Our backend engineers are expected to uphold the values “Go Bold” and “All for One” as they work to transform our systems and organization and contribute to our service's growth.
