Software Engineer, iOS - Mercoin in Tokyo, Japan
On April 28, 2021, Mercari Group established Mercoin, Inc., a company dedicated to developing services related to cryptoassets and blockchain technologies. Through its involvement in the cryptoasset business, Mercoin aims to streamline users' access to financial services within the Mercari marketplace app. This includes enabling users to receive payments for their Mercari sales in bitcoin and providing a comprehensive wallet function that encompasses not only Merpay's payment and remittance services but also credit, cryptoassets, and asset management features.
Mercari has also ventured into the realm of blockchain technologies, opening up new avenues for individuals to exchange value. The company's vision is to redefine the concept of buying and selling, making it effortless for everyone to exchange value in various forms, including not just physical possessions and currency, but also services and digital content like non-fungible tokens (NFTs).
At present, Merpay/Mercoin is actively seeking iOS engineers who can handle all aspects, from planning to the development of new payment and financial services. Merpay/Mercoin manages multiple projects running in different directions simultaneously, and each project team, typically comprising about 10 members, includes between 1 to 3 iOS engineers. Integration with the Mercari app necessitates close collaboration between our engineers and the Mercari development teams, demanding a high level of professional expertise from our iOS engineers.
In terms of technology, our development is based on MVVM architecture for UIKit and a Redux-inspired architecture for SwiftUI. We place a strong emphasis on the implementation of unit tests and UI tests, continuously testing these with CI and striving to enhance coverage.
