Software Engineer, Frontend - Mercari in Tokyo, Japan
Mercari is gearing up for a new venture aimed at advancing the concept of a circular economy. The dedicated team is working diligently to establish a user-friendly resale service platform accessible to both individuals and businesses. The ultimate goal is to create a system that can unlock the estimated 43.7 trillion yen worth of "hidden assets" in Japan, thereby further expanding the country's secondhand market, which is presently valued at around 3 trillion yen.
To put it concretely, our business approach revolves around normalizing the reuse of items by breaking down the conventional boundaries between online and offline platforms, as well as between primary and secondary distribution. This represents Mercari's maiden endeavor in such an ambitious undertaking, and it harbors significant untapped potential.
*(Learn more about Mercari's mission and values here.)
*The concept of "hidden assets" refers to the value derived from the quantity of unused items present in households across Japan, as determined through surveys. This value is converted into Japanese yen by utilizing the average transaction value observed on Mercari. In this context, "unused items" pertain to items that have not been put to use for at least one year, yet continue to occupy space in households without a specific reason for their retention.
Specific work responsibilities include the following:
- Lead the initiation of a novel platform within the Recommerce sector.
- Opt for the appropriate technologies and devise the system architecture and requisite specifications essential for platform development.

In your capacity, you'll be actively engaged in the development of a fresh platform aimed at advancing secondary distribution. Furthermore, you will play a pivotal role in various decision-making processes during the 0 to 1 phase of our business.
