To build our Payment services, we got technical cooperation from Paytm (A large payment service company in India). And based on their customer-first technologies , we created and expanded the smartphone payment service in Japan. Therefore, we have decided to establish a development base in India, because it is a major IT country with many talented engineers, as evidenced by the fact that cutting-edge mobile payments can continue to be generated.
OUR VISION IS UNLIMITEDPayPay is looking for a Frontend Developer to build and scale UI/Product experiences for our web applications. You’ll work closely with Product, Design, and Backend teams to deliver high-quality features, contribute to a growing design system.
Primary Responsibilities- Deliver product features end-to-end: translate requirements into clean, scalable UI implementations with well-structured components and predictable data flow.
- Build reusable UI components and patterns: contribute to and extend our design system using tools like Storybook; prioritize consistency, accessibility basics, and developer ergonomics.
- Integrate APIs and handle real-world states: implement robust data fetching patterns (pagination, caching, retries), and manage loading/error/empty states with clear UX behavior.
- Write maintainable, modular code: apply good separation of concerns (presentation vs business logic vs API layer), meaningful abstractions, and clear naming; keep codebase easy to extend.
- Optimize performance and reliability: identify bottlenecks (rendering, network, bundle size), apply pragmatic improvements (memoization, debouncing, virtualization where relevant), and avoid async pitfalls (stale responses, race conditions).
- Improve engineering quality: participate actively in code reviews, raise the bar on standards, and help enforce best practices around testing strategy, i18n, and build tooling.
- Collaborate cross-functionally: work closely with PM/Design/Backend to clarify requirements, propose tradeoffs, and deliver iteratively with high ownership.
- Support operational excellence: use observability tooling (e.g., Sentry, New Relic, Kibana) to debug production issues, measure impact, and improve stability.
- Grow toward full-stack ownership (optional path): partner with backend teams and gradually take on BFF/API contributions using Node.js (NestJS/Express) as needed.
Frontend: Typescript/Javascript , React/Vue, single-spa, Webpack, Jest, Storybook, i18n , micro-frontend
Middlewear : NestJS, Express
Infra/CI: AWS, Docker, Kubernetes, ArgoCD, Terraform, GitHub Actions, Jenkins
Obs/Analytics: Sentry, Kibana, New Relic, Google Analytics, Firebase
Qualifications- 4+ years of professional frontend development experience.
- Strong JavaScript fundamentals.
- Solid experience in React and/or Vue.
- Proven ability to write readable, modular, production-quality code.
- Strong problem-solving skills with practical DSA (web-relevant) comfortable reasoning about time/space complexity.
- Performance awareness: can identify bottlenecks and implement pragmatic optimizations.
- Ability to do low-level design (LLD) for frontend features: break down requirements into components/modules, define interfaces, and plan implementation in milestones.
- Good communication: can explain approach and tradeoffs clearly.
- Leverage AI/LLM based tools in daily workflows
- Experience with Nest.js (routing, SSR/CSR tradeoffs, data fetching strategies).
- Experience with Node.js or API integration patterns (REST, pagination, auth flows, error handling).
- Familiarity with design systems, accessibility basics, and responsive UI patterns.
- Exposure to frontend observability (error logging, basic performance metrics).
- Experience with micro-frontends (e.g., single-spa) or large-scale frontend architectures.
- You can independently deliver a feature end-to-end with clean architecture and reliable async handling.
- Your code is modular, maintainable, and performance-conscious.
- You contribute to consistent UI patterns and raise team quality through reviews and collaboration.

What We Do
PayPay, a FinTech company, that achieved more than 60M users within around 5 years since its launch in 2018 has hugely diversified employees who are from about 50 different countries. The number of employees by now is more than 1,000 staff members, and yet the company is still incomplete and at a growing stage. To build "PayPay", we allied with Paytm, the biggest payment service company in India. Based on their customer-first technologies , we created and expanded the smartphone payment service in Japan. Our biggest competitor is "cash". We are seeking for people who can accept this challenge positively, brush up the product at a tremendous speed that other companies could never achieve, and who are passionate about promoting and spreading such a financial life platform in a short time along with professionalism. About our working style, we had introduced a new personnel system called WFA (Working From Anywhere*). At PayPay, we work fully remotely in Japan. Therefore, the working place or your living place doesn't matter. Even if you are living in a local area, the salary and benefit package will be at an international level while you enjoy working with world class colleagues. You will find such a way of working at PayPay! *This WFA policy is applicable only within Japan
