What is Mercari?
The Mercari Group operates Mercari, Japan’s largest marketplace app where anyone can exchange their loved goods from their smartphones, and Merpay, the easy-to-use mobile payment service within the Mercari app. With our mission to create value in a global marketplace where anyone can buy & sell, we have released the Mercari app in Japan and the US. Established in 2013, Mercari has grown in size to over 1,800 employees. Our diverse team members are from around 40 countries and regions, with each possessing different skills and backgrounds. Together, we are aiming to create a service from Japan which can be used anywhere in the world.
Engineering at Mercari
At Mercari, we take challenges every day in order to fulfill our mission to create value in a global marketplace where anyone can buy & sell. We are continuously striving to create a society where everyone can do the things they like. In order to make this a reality, our most important job is to give our users the best experience possible. For that, Mercari’s engineering organization aims to be a place where engineers can go bold, choose the latest and best technology to use, and autonomously make decisions and take on challenges at a rapid pace.
Engineering Bold Challenge
Creating systems, organizations, and services used around the world
The Mercari marketplace app has grown into a service used by more than 15 million people each month, but our goal is to “create value in a global marketplace where anyone can buy & sell.” We’re not satisfied with just Japan—we want to evolve Mercari into a service used all over the world. To do so, we need to select the right technology for the job and create unique services and systems with our own hands.
Taking ownership, making decisions, and taking action in an evolving organization
Mercari’s ideal engineering organization is a coordinated and flexible organization where each individual can take ownership of their work and make their own decisions. In order to provide the best user experience, everyone should be able to test out their own ideas. This is what we call “microdecisions.” We believe that the more attempts you make, the more accurate your strategies will become, and the more growth you’ll see as an engineer.
Diversity & Inclusion
Working to achieve our mission in a strong team leveraging each individual’s skills and diversity
Mercari aims to create value in a global marketplace, and we place a strong emphasis on diversity in our organization and team members. It’s not an easy task for members of all different backgrounds, including languages, cultures, and values, to come together as one, but we believe that treating these differences as strengths helps us create a strong engineering organization ready to compete on a global scale.
We have engineers with many diverse backgrounds and experiences at Mercari working towards achieving our mission.
