Corporate Data

Join the first and only tech unicorn in Japan!

Mercari’s mission is to create value in a global marketplace where anyone can buy & sell. Today, we proudly count over 75 million downloads of the Mercari app worldwide, making us one of the most downloaded apps in Japan.

We have always been committed to our goal of expanding overseas, and within a year and half of the Mercari app launch, we started our service in the US. With the recent release of the app in the UK, the majority of our product team is working on the global expansion of our service.

Mercari’s culture allows you to continually demonstrate a high level of professionalism, do everything possible to succeed, and to think and act boldly.

Our core values are simple:
• “Go Bold”: Aim for innovation and creative destruction that impacts the world.
• “All for One”: As team, collectively and cooperatively work towards a unified goal.
• “Be Professional”: Use your talent and expertise to the fullest potential; take ownership, and be willing to enhance your skills and abilities through work.

We still have to increase our presence in each region, targeting not only North America and Europe, but countries in Asia and Africa as well. Once we have established ourselves in many regions, our next hurdle will be crossborder transactions. At that point, we will need to tackle global logistics and payments, as well as create our own automated translation system using natural language processing.

We strive to bring our vision to reality. We are continuously looking for young talent to spearhead the development of our marketplace app and global expansion of our services.

Mercari is seeking software engineers and changemakers to join the Tokyo headquarters. If you’re looking for a job where you will be challenged, encouraged to revamp your skills with new technology, grow professionally, and collaborate with a team of extremely capable engineers, developers, and business managers: this job is for you.
