RemoteHybridUkraine · Remote-firstFull-timeMiddle

We're hiring a Middle Frontend Developer who ships polished interfaces and cares about performance, accessibility, and maintainable React code. You'll own features from implementation through code review and release, working with designers, backend engineers, and QA on client products. You balance speed with quality and can explain trade-offs clearly to the team.

Key responsibilities

  • Build responsive web interfaces with React, Next.js, and TypeScript in production codebases
  • Implement and extend design systems, shared UI primitives, and layout patterns
  • Integrate REST or GraphQL APIs, manage client-side state, and handle async data flows
  • Improve Core Web Vitals, bundle size, and perceived performance on real user devices
  • Apply accessibility standards (WCAG-oriented markup, keyboard navigation, ARIA where needed)
  • Write and maintain unit, component, or E2E tests for critical user flows
  • Participate in code review, sprint planning, and estimation for frontend work
  • Debug production issues across browsers and devices with structured reproduction steps
  • Collaborate with designers on feasibility, responsive behaviour, and interaction details
  • Document component APIs, conventions, and setup steps for other engineers on the project

Requirements

  • 2+ years of commercial experience building web products with React
  • Strong TypeScript skills and confidence refactoring legacy or inherited UI code
  • Production experience with Next.js App Router, routing, SSR/SSG, and metadata patterns
  • Solid command of modern CSS, including Tailwind CSS or similar utility-first workflows
  • Understanding of accessibility, responsive layout, and cross-browser compatibility
  • Experience integrating APIs, handling auth flows, and managing forms with validation
  • Comfortable with Git workflows, feature branches, and collaborative pull request culture
  • Ability to break down tasks, estimate effort, and deliver within agreed sprint scope
  • English: Upper-Intermediate (B2) or higher for stand-ups, documentation, and client calls

Nice to have

  • Experience with React Native, Expo, or shared component strategies across web and mobile
  • Familiarity with Playwright, Vitest, Testing Library, or Storybook
  • Contributions to internal component libraries, design tokens, or documentation sites
  • Exposure to analytics, error tracking (Sentry), or feature-flag tooling
  • Previous work in agencies, product studios, or fast-moving startup environments
