Senior Frontend Developer

Senior Front-End Engineer (React/TypeScript • Web + Mobile)

Join us to own major product features end-to-end in a modern, well-architected monorepo,no legacy rescue work here. Youll ship polished experiences across web and mobile using React 19 + TypeScript 5.9, React Router 7 (SSR), Vite, and a shared design system. If you care about craft, autonomy, and AI-augmented speed, you’ll fit right in.

What You’ll Do

• Lead complex product work such as

  payment flows

  with Stripe, robust form validation, real-world edge cases,and ship with tests and monitoring.
• Build

  cross-platform features

  that share logic across React (web) and React Native 0.81/Expo 54 (iOS/Android) using our custom shared packages, with Cloudflare Workers powering SSR for fast first paint.
• Evolve our

  design system

  (100+ components) with accessible, composable primitives built with Tailwind CSS; contribute extensible component patterns, design tokens, and comprehensive docs; ensure WCAG AA+ and great keyboard/screen-reader support.
• Deliver

  data-heavy interfaces

  using TanStack Query and React Table (virtualization, sorting, filtering, optimistic updates), while keeping performance and UX crisp.
• Partner with design and product to clarify requirements, surface risks, propose alternatives, and plan incremental rollouts; measure outcomes via Sentry and FullStory.
  

What We’re Looking For

• 8+ years building production applications for thousands+ users; 4+ years deep React expertise (hooks-era and beyond); 6+ years JS/TS.
  
• Proven in large-scale products: real CI/CD, code review, observability, incident response, and long-term maintenance,not just prototypes or internal tools.
  
• 3+ years implementing

  high-fidelity designs

  from Figma/Adobe XD in a product environment: pixel/snapping discipline, responsive intent, motion/micro-interactions, and typography craft.
• Experience in

  React Native

  (2+ years strongly preferred) shipping to both iOS and Android with Expo; comfortable sharing code across platforms.
• Fluency with our stack’s patterns: pnpm + Turbo monorepo, Vite, React Router 7 SSR, TanStack Query, Formik, Storybook, Vitest/Playwright, and visual regression testing.
  
• Strong systems thinking for

  design systems

  : tokens, theming, accessibility, composable APIs (Ariakit-based components), and avoiding one-offs.
• AI-augmented workflow: you regularly use tools like Claude/Copilot/Cursor for research, scaffolding, tests, and refactors,and you

  critically review

  every line.
• Clear communicator: writes concise docs, reviews PRs thoughtfully, and explains trade-offs to technical and non-technical partners.
  

Why This Role Is Different

• Modern foundation, not a cleanup job:

  a 2025-grade React/TypeScript monorepo with conventions, tests, and a mature component library so you spend time building,not untangling debt.

• Real ownership:

  take a Figma spec to production, shape the architecture, call out risks, and drive incremental launches backed by metrics.

• AI-forward culture:

  we expect AI to accelerate craft, not replace it,use it for speed, keep judgment and quality as the bar.

• End-to-end impact:

  from API contracts and state strategy to polish, accessibility, and performance.
