About the role

We’re building modern web & mobile experiences for a high-impact platform. You’ll own end-to-end delivery across React (TypeScript) and Flutter (Dart)—fast UIs, clean state, solid tests, analytics, and dependable releases.

What you’ll do

  • Ship responsive React (TS) features and Flutter screens with excellent UX/perf

  • Write unit/integration tests (Jest/RTL, flutter_test); participate in code reviews
  • Prepare reliable mobile releases (signing, CI, App Store / Google Play submissions)
  • Contribute to design system, accessibility (WCAG), and i18n/RTL (Arabic is a plus)
  • Collaborate with Product/Backend in two-week sprints

Must-have

  • 5+ yrs building production apps; 3+ yrs React (TS); 2+ yrs Flutter (Dart)
  • Strong component architecture, hooks, state, and performance profiling
  • Testing (Jest/RTL, flutter_test), CI/CD, Git workflows
  • API integration (REST/GraphQL), forms, pagination, caching, secure auth flows
  • Track record releasing Flutter apps to both stores
  • Clear English communication; product mindset; async-friendly

Nice to have

  • Next.js, Vite, Tailwind/MUI, design-system experience
  • Push notifications, deep links, Firebase (Crashlytics/Analytics/Remote Config)
  • Basic AWS front-end ops (S3/CloudFront), performance budgets/Lighthouse
  • Experience with Arabic/RTL and accessibility best practices
