Senior Front-End Engineer

What You’ll Do

• Lead complex, real-world product initiatives (e.g., payment flows, advanced validation, state-heavy UX) with reliability, tests, and observability.
• Build

  shared, cross-platform features

  from a unified monorepo across React Web and React Native (Expo), with SSR powered by Cloudflare Workers for exceptional performance.
• Evolve a

  mature design system (100+ components)

  —creating accessible, composable, well-documented primitives using Tailwind, tokens, and WCAG-AA+ standards.
• Deliver

  data-intensive experiences

  with TanStack Query + React Table (virtualization, filters, sorting, optimistic updates) while keeping UX fast and fluid.
• Collaborate with Product & Design to clarify requirements, de-risk decisions, plan incremental rollouts, and measure outcomes via Sentry / FullStory.
• Contribute to engineering excellence: CI/CD maturity, code quality, architectural clarity, and long-term maintainability.
