About the role

Role Overview

Build highly responsive, intuitive user interfaces for complex web applications. You’ll own frontend architecture end-to-end—from concept through deployment—ensuring seamless, high-performance experiences across devices and modern browsers.

Responsibilities

  • Develop and maintain consumer-facing web applications using React, TypeScript, and modern styling (e.g., Tailwind CSS)
  • Optimize application performance to meet Core Web Vitals (rendering speed, code-splitting, lazy loading, asset optimization)
  • Build and maintain a reusable UI component library aligned with a design system and WCAG 2.1 AA accessibility requirements
  • Integrate with RESTful APIs and GraphQL endpoints; manage client-side state efficiently using Zustand, Redux, or React Query
  • Write and maintain automated tests: unit, integration, and end-to-end using Jest, React Testing Library, and Cypress
  • Participate in code reviews and technical design discussions; collaborate with backend teams to define clean API contracts

Requirements

  • 3–7 years of professional software engineering experience in modern frontend web development
  • Strong proficiency in TypeScript, modern JavaScript (ES6+), HTML5, and CSS3, including browser rendering fundamentals
  • Proven experience building and scaling production applications with React and its ecosystem
  • Experience with frontend tooling/build pipelines: Vite, Webpack, ESLint, and CI/CD automation
  • Bachelor’s degree in Computer Science (or equivalent practical experience)

Nice to Have

  • Next.js
  • GraphQL with Apollo Client
  • Node.js integration (backend)
  • React Native (mobile development)
