Software Engineer, Backend - Mercari in Tokyo, Japan
Team Mission / Work Responsibilities
Mercari is gearing up to introduce a new venture aimed at bolstering the development of a circular economy. The team responsible for this new endeavor is diligently crafting a resale service platform that's accessible to both individuals and businesses. Their goal is to establish a mechanism for reinvigorating the substantial 43.7 trillion yen worth of "hidden assets" in Japan. The overarching aim is to further broaden Japan's secondhand market, which is presently valued at around 3 trillion yen.
To be more specific, our enterprise revolves around normalizing the reuse of items by erasing the boundaries between online and offline domains, as well as between primary and secondary distribution channels. This represents Mercari's first foray into such a challenge, and it harbors significant untapped potential.

Specific work responsibilities include the following:
- Take the lead in spearheading the launch of a novel platform in the Recommerce sector.
- Determine the appropriate technologies and formulate the system architecture and specifications required for the development of this new platform.
- Devise and execute APIs by leveraging the Google Cloud Platform and employing the Go programming language.
The term "hidden assets" refers to the valuation of unused items present in Japanese households, converted into Japanese yen based on the average transaction values on Mercari. "Unused items" are items that have not been utilized for at least one year but continue to be retained in households without a specific purpose.

Given that this team consists of a limited number of individuals, you'll be tasked with shouldering a diverse array of responsibilities to ensure the successful inauguration of this new venture.
In your capacity, you'll be instrumental in the development of a fresh platform that fosters secondary distribution and play a crucial role in the decision-making processes during the initial phase of transitioning from 0 to 1 in our business. Consequently, we are seeking someone who is not merely content with utilizing and expanding Mercari's existing systems but is eager to surpass those boundaries.

- A track record of launching new services and addressing the challenges associated with the growth phase of a service.

- Experience in developing and maintaining large-scale, high-traffic systems.
