PaypayPayPay Bank is responsible for developing the financial infrastructure that supports the financial services of the PayPay Group. Our team is driven by our in-house engineers, from the design and development of the core system to its operation. Our role is not just to develop functions, but to evolve the system while maintaining high reliability, design an architecture that anticipates future service expansion, and create the development organization and development process itself. Because it is a new organization, you can proactively participate in technology selection and the creation of development culture. After joining the company, you are expected to be seconded to PayPay Bank as a member of the above project. We are accelerating the modernization of PayPay Bank’s customer-facing website and internal back-office systems. To support this transformation, we are looking for hands-on and collaborative Frontend Engineers who can take ownership of product delivery, work closely with cross-functional teams, and help us build scalable foundations for future development. You will have the opportunity to contribute not only to individual product features, but also to frontend architecture, development processes, and engineering standards across the organization. Work with Product Managers, Designers, Backend Engineers, and QA Engineers to deliver features. Review product requirements and Figma designs, and suggest improvements. Design and implement frontend solutions using Vue.js and TypeScript. Align API requirements with Backend Engineers. Work with QA Engineers on testing and issue resolution. Monitor released features and resolve production issues. Participate in code reviews and improve frontend best practices. Some important banking services still run on legacy JSP systems. Their business rules and workflows may be spread across old code, documents, and team knowledge. Frontend Engineers work with Product Managers and business teams to understand the current behavior, clarify hidden requirements, and simplify complex workflows. Based on this understanding, engineers propose modern and maintainable technical solutions. The challenge is not simply rewriting old code. It is to understand the existing business rules and dependencies, decide what should be kept, improved, or removed, design modern frontend architecture and API integrations, migrate step by step without disrupting banking operations, and turn complex legacy systems into solutions that are easier to maintain and develop. For new features, you will not only receive a design and implement it. You will be involved from the beginning to the end: understand the product idea, suggest product and design improvements, review Figma designs with Designers, design the frontend solution, align API requirements with Backend Engineers, implement and test the feature, support QA and release, and monitor the feature after release. You will have the freedom to propose solutions and take ownership of your feature. We encourage engineers to identify problems and create improvement proposals. You can propose improvements to the product, user experience, architecture, or development process. We also keep meetings simple and protect engineers’ focus time.
