About the position

Both our KOMOJU application and engineering teams are growing rapidly, and we need a UI that can do likewise. We are looking for engineers skilled in frontend development to help us build a UI layer that brings as good of an experience to our developers as it does to our end users. As our customer base and offerings expands, you will help us build a platform that can handle payments on a global scale.

Our current application is built using React and Next, with some other application using Vue.js. and growth-mindset who can contribute regardless of frontend framework. We have a need for individuals who are passionate about making a great visual and interactive experience for end users as well as for those who know how to design great APIs and front end workflows for other developers.

Our ideal candidate has experience working with large legacy web applications and bringing them up-to-date. They will know how to build reliable, performant components that contribute to high-velocity, scalable frontend development, while also being able to make tradeoffs when needed and effectively communicate risk to our product stakeholders.

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

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.

Nice to haves

While not specifically required, tell us if you have any of the following.

  • 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

Compensation

Includes (rough estimate of) profit share. Based on experience and skill level.
