About Mercari

Mercari is a marketplace app that makes it easy for people to safely sell and ship their things. Launched in 2013, the Mercari app has been downloaded over 100M times, and is now among the largest peer-to-peer selling platforms globally.

Our mission

The world is full of objects and services being produced and sold, but many of them are thrown away without people realizing that they might be valuable to someone else, wasting valuable natural resources. To contribute towards eliminating waste, we have launched Mercari, a marketplace where people can buy and sell easily and safely.

The goal of the engineering organization

At Mercari, our organization constantly welcomes changes and new challenges, cooperates and co-creates, is diverse, offers freedom, and encourages all of us to take ownership and make our own decisions.

We are open to overseas candidates looking to relocate to Japan, and will support you in obtaining your visa.

About the position

Although the Mercari API was designed and implemented as a monolithic API, we are working on migrating the API to microservices. This will allow us to divide responsibilities and make technological investments for a stronger system and organization capable of handling even greater expansion. Of course, we will continue to run our services as we implement these changes, and we aim to make daily improvements to provide an even better experience for our customers.
