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 product‐aligned and does not involve blockchain or smart contracts.

Engagement: Long‐term full‐time or part‐time (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 end‐to‐end: discovery, plan, execution, and measurement
Refactor legacy components into clean, typed, reusable UI building blocks
Improve routing, loading states, error boundaries, and data‐fetch 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 CI‐friendly checks
Collaborate with design and backend to ship features with smooth handoffs
Document decisions, developer ergonomics, and contributor guidelines

Required Experience

3+ 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, CSS‐in‐TS 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 data‐fetch 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 high‐value 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 one‐off 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: type‐safe code, lint‐clean, tests where they add value

Intro chat (30 min): role, product, your experience
