About Pay Pay Card

Pay Pay Card Corporation was established in 2021 to provide users a Fin Tech service that is more accessible and convenient compared to previous credit cards and credit services, by integrating with the Pay Pay payment platform, which has surpassed
70 million users since its launch (as of July 2025).

We are looking for people who are passionate about refining our products at an overwhelming speed that other companies cannot match, as well as professionals who are interested in promoting the spread of cashless payments in Japan and the use of these payments as a financial life platform. Let us work together to create new value for users.

※ Please note that you cannot apply or be selected in parallel with Pay Pay Corporation, Pay Pay Card Corporation and Pay Pay Securities Corporation.

We are looking for web frontend engineers to work on the Pay Pay Card mini-application, and other web frontend, with a laser focus on scalability and maintainability.

Pay Pay Card aims at revolutionizing the credit card industry, making payment easier than ever, from two different angles:

• Bring the credit card experience to the next level: we have many functionalities in the pipe to improve our product, not to mention the integration into the Pay Pay ecosystem as Pay Pay Card is part of the Pay Pay Group.
• (Re-)architect our systems landscape: we want to reassess our frontend systems relevancy and update the architecture according to our product & technical roadmap. It is bundled with difficult design challenges to solve: we simply want to get it right.

As a fast-paced company leading the payments industry, we need our engineers to be versatile and enthusiastic to take on new challenges in order to stay at the forefront. Indeed, we strive for continuous improvement within our systems as well as outside our systems. Additionally, we value communication, to smoothly cooperate with other teams, and inclusivity, to efficiently navigate in a multicultural environment.
