Frontend Engineer (React/TypeScript) — Product Upgrade Focus

We're looking for a Frontend Engineer to lead a modernization and feature upgrade of our React + TypeScript web app. This role is fully productaligned and does not involve blockchain or smart contracts.

Engagement: Longterm fulltime or parttime (minimum 10 hours/week)

About The Project

Our codebase (socialfi-caw-test-v1) is a React 18 + TypeScript application built with Vite. It includes routing, modular screens/components, UI themes, and an Express-based backend for auth/media. Your mandate is to elevate the frontend experience: performance, UX polish, component quality, accessibility, and

maintainability.

What You'll Do

• Own the frontend upgrade roadmap endtoend: discovery, plan, execution, and measurement
• Refactor legacy components into clean, typed, reusable UI building blocks
• Improve routing, loading states, error boundaries, and datafetch handling
• Tighten state management patterns and store structure for clarity and testability
• Optimize performance (bundle size, code splitting, memoization, virtualization where needed)
• Establish UI consistency via shared design tokens, themes, and component conventions
• Raise product quality: accessibility (a11y), responsiveness, keyboard navigation, i18n readiness
• Add automated tests (unit/integration/E2E) and adopt CIfriendly checks
• Collaborate with design and backend to ship features with smooth handoffs
• Document decisions, developer ergonomics, and contributor guidelines
  
  

Required Experience

• 7+ years building production React apps with TypeScript
• Strong command of component design, props modeling, and hooks
• Proficiency with modern bundlers (Vite/webpack), code splitting, and performance profiling
• Practical experience with state management (e.g., MobX/MST, Redux, Zustand) and async flows
• Comfort with routing solutions (React Router) and data fetching patterns
• Solid CSS skills (responsive layout, theming, CSSinTS or utility styles)
• Testing experience with one or more: Vitest/Jest, React Testing Library, Playwright/Cypress
• Excellent code quality habits: typings, reviews, linting, and maintainable abstractions
  
  

Nice to have

• Familiarity with accessibility standards (WCAG) and semantic HTML
• Experience building design systems or component libraries
• Performance tuning (React Profiler, Lighthouse, bundle analysis)
• DX improvements: ESLint/Prettier configs, commit hooks, Storybook
• Basic Node/Express understanding for local integration and API contracts
  
  

What You'll Deliver (first 90 Days)

• A prioritized upgrade plan with clear milestones and success metrics
• Refactored core UI (navigation, header/footer, shared layout, loading/errors)
• Standardized state management and datafetch patterns across screens
• Performance improvements with measurable gains (LCP/TTI, bundle size)
• Accessibility and responsive checks across key flows
• A baseline test suite running in CI (unit + a few highvalue E2E checks)
• Developer docs: architecture overview, conventions, and contribution guide
  
  

Our stack (current and target)


React 18, TypeScript, Vite

Routing: React Router

State: MobX/MST (existing) — open to incremental improvements where it adds clarity

Styling: theme tokens + CSS utilities (improve consistency, avoid oneoff styles)

Testing: Vitest/Jest, React Testing Library Playwright/Cypress for E2E

Tooling: ESLint, Prettier, pnpm/npm

How We Work

Pragmatic, incremental refactors with steady feature delivery

Collaboration via issues/PRs, small reviewable edits, and clear acceptance criteria

Quality gates: typesafe code, lintclean, tests where they add value
