About Mercari

Circulate all forms of value to unleash the potential in all people

"What can I do to help society thrive with the finite resources we have?" The Mercari marketplace app was born in 2013 out of this thought by our founder Shintaro Yamada as he traveled the world. We believe that by circulating all forms of value, not just physical things and money, we can create opportunities for anyone to realize their dreams and contribute to society and the people around them. Mercari aims to use technology to connect people all over the world and create a world where anyone can unleash their potential.

• Engineering Culture

Mercari has been operating marketplaces localized in two countries, Japan and the United States, and the Crossborder team recently released a new global app , already in use in Hong-kong and Taiwan that we aim to deploy  in over 100 countries. For requests from each region, it must be developed with a global perspective, including standardization and consolidation to avoid excessive localization.

The integration of Crossborder e-commerce and local business is heavily reliant on a robust logistics network and efficient operations. This necessitates working closely with numerous third-party vendors. Through this experience, you will acquire a wide range of business knowledge and apply it to engineering, collaborating closely with teams such as product and operations.

Trade-offs will have to be made to build a strong foundation while assuring a reasonable time to market. The team must balance short-term initiatives and the long term goal for the Global Product. Constructive discussions that transcend individual job roles, whether you are an engineer or a Business Developer, are essential for moving forward effectively.
