About PayPay

Since its launch in 2018, PayPay, a fintech company, has surpassed 70 million users in approximately 7 years and is composed of diverse members from about 50 countries and regions.

OUR VISION IS UNLIMITED_

We believe that a clear vision is not necessary to create a future beyond our imagination. PayPay's stance is to always remember it's Day 1 and to realize a vision (future) that no one can imagine. We are looking for colleagues who are passionate about tackling this grand vision, refining products at an overwhelming speed that cannot be imitated by other companies, and professionally promoting the widespread adoption of cashless payments in Japan and its use as a financial life platform. We seek individuals who can proactively identify challenges, collaborate with others, and jointly promote the creation of new value.

About the Work

Introduction to the PayPay Financial Business Strategy Division

This is the execution unit that aims to achieve the company-wide mission of making PayPay the No.1 Fintech company by creating all money-related use cases on the PayPay app (in addition to "spending," also "saving," "increasing," "borrowing," "preparing," and "managing"). We will also be inventing UI/UX for smartphone-first financial services, so our members consist of individuals with diverse experiences, skills, and perspectives, such as those who have experienced new business development at major financial institutions, those involved in new businesses overseas, and those with expertise in data. We want to work with people who have a strong passion for improving current financial services.

• Organizational Structure: The current Financial Strategy Division consists of about 50 members, ranging from late 20s to late 40s. There are also nearly 10 data analysts and data scientists within the division.

Background of Recruitment

To expand the UI/UX of smartphone-first financial services, we need to realize solutions to user problems (most of which do not yet exist in the world) through UI/UX and services. However, user problems are often invisible. Users won't tell you about them. We believe that only those with a strong passion for improving financial services can discover these problems, structure them, and elevate them to solutions. We want new hires to achieve truly user-first financial services.
