Introduction
Our Mission
Mercari is a Japan-based company with the mission of “creating value in a global marketplace where anyone can buy & sell.” Having continuously worked toward this goal since our founding in 2013, we are now transforming from a startup into a global player. While this transformation brings its own specific set of challenges, we believe that solving them one after another will allow us to fully achieve our mission. Are you interested in working together to take on these exciting challenges?
Our Culture
Mercari’s culture has been central to the company since our founding, with the three core values of Go Bold, All for One, and Be a Pro. In addition, the “Trust & Openness” value was introduced to embody our culture of mutual trust, where information remains transparent and rules are kept to a minimum. Regardless of how big Mercari gets, our culture is essential to achieving our mission and will be promoted throughout our organization.
Position Overview
Work Responsibilities
On April 28, 2021, Mercari Group established Mercoin, Inc. Mercoin is a new company developing services related to cryptoassets and blockchain technologies. By taking on the cryptoasset business, we will make it even easier for users to utilize financial services within the Mercari marketplace app, such as by allowing users to receive payment for Mercari sales in bitcoin and providing a single wallet function that incorporates not only Merpay’s payment and remittance services, but credit, cryptoassets, and asset management features as well.
Mercari has also started work on blockchain technologies, which present new opportunities for individuals to exchange value. The company wants to redefine what it means to buy and sell, enabling anyone and everyone to easily exchange value in all its forms—not only as belongings and money, but services and digital content like non-fungible tokens (NFTs).
Currently at Merpay/Mercoin, we are looking to hire iOS engineers who can handle everything from planning to development of the new payment/financial services. Merpay/Mercoin has multiple projects moving in different vectors simultaneously, and the teams of 10 or so members which comprise each project have between 1 to 3 iOS engineers on board. Integration with the Mercari app requires our engineers to communicate with the Mercari development teams and study the tech used by the Mercari app, calling for a high level of professional skill from our engineers.
In terms of technologies, our development uses simple architecture based on MVVM. We work on implementation of unit tests and UI tests, while also working to constantly test these with CI and improve coverage. While naturally the team is involved with developing features for projects, our company culture encourages engineers to proactively improve development processes, automate processes using CI, and other tasks. We believe that this culture allows our software engineers to improve their abilities not only in iOS, but in many other domains as well. Specific work responsibilities include:
Launch new products for Mercoin
Design/develop new Merpay features and improve existing features
Design/develop SDK for integration with Mercari
