Frontend Engineer

Summary

Join KOMOJU, a leading cross-border payment gateway in Japan, and be part of our growing engineering team. We are seeking skilled frontend engineers to build and enhance our UI layer for both developers and end-users. You will work with React and Next.js (Vue.js experience is a plus), building reliable, performant components for a globally scalable platform. Experience with large legacy web applications and a strong understanding of design systems are highly valued. The role requires collaboration, independent work, and effective communication in a remote environment. We offer a remote-first work environment with additional benefits.

Requirements

• 3+ years of professional experience with modern SPA frameworks and libraries such as React (Vue.js is a plus, but not a requirement)
• Experience in building and maintaining a design system and reusable component library
• Experience with building pages that look good and perform well at any screen size from only written product specs or low-fidelity mockups
• Comfortable with troubleshooting and debugging throughout the whole stack
• Good communicator with experience in product development in remote/asynchronous communication environments
• Experience in integrating RESTful APIs to build dynamic and data-driven user interfaces

Responsibilities

• Deliver reliable frontend pages and components in a fast-paced environment
• Support teams through code review, developer surveys, and outreach
• Write tests that validate the stability and correctness of implementations
• Reduce tech debt and be able to plan for the long term—our engineers will have to live with the systems we create for some time
• Know how to get things done independently, but be able to work within a team to develop strategy and level up your colleagues on all things frontend

Preferred Qualifications

• Experience with Typescript
• Experience with the build toolchain of JavaScript/TypeScript such as Vite, Webpack, or Turbopack
• Experience with Playwright/Storybook/BrowserStack or similar
• Experience with Ruby on Rails
• Experience with multi-lingual applications (i18n)
• Experience with accessibility (a11y)
• Experience with observability (o11y)
• Experience creating open source libraries

Benefits

• At Degica, we embrace remote work while also offering office space for those who prefer in-person collaboration
• 10 days regular vacation, additional 5 days summer and 5 days winter vacation
• Paid birthday holiday
• Budget for self-learning allowance, to ensure our employees’ skills remain current
• Language training for Japanese
