About the role

Role Overview

Senior Front-End Engineer (React) working across the full frontend lifecycle to build user-facing experiences for onchain financial infrastructure.

What You’ll Do

Participate in all phases of frontend development: requirements analysis, architecture/design, implementation, documentation, testing, and delivery.
Build responsive, accessible UI from Figma designs.
Prototype interfaces for MVPs.
Create and maintain reusable components documented in Storybook.
Integrate new features into the existing codebase.
Implement blockchain and wallet interactions.
Design client-side state management strategies, including:
- server-state synchronization, caching, and error handling
- client state management and when to use which approach
Write unit, integration, and end-to-end tests.
Monitor production issues and performance using Sentry.
Contribute to estimation, planning, and technical decision-making.
Review peers’ code and help maintain engineering standards.
Communicate effectively with engineers, designers, product stakeholders, and partners.

Who You Are

Expert in modern React and TypeScript, with strong instincts for component architecture and type-safe design.
Production experience with Next.js, Vite, and pnpm-based monorepos.
Deep understanding of state management:
- server state with TanStack Query
- lightweight client state with Zustand (or similar)
Strong CSS and responsive design fundamentals; experience with component libraries such as Chakra UI.
Ability to translate Figma designs into accessible, reusable components, ideally documented in Storybook.
Solid testing practice across unit/integration/E2E, including Vitest and Playwright, especially for async and wallet-interaction flows.
Strong performance optimization skills (e.g., code splitting, memoization, bundle analysis, Core Web Vitals) and production debugging with Sentry.
Security-conscious (e.g., CSP, secure wallet interactions, input validation, safe secret handling).
Confident with Git workflows, Docker, and GitHub CI/CD; basic familiarity with Kubernetes and CDNs.

Nice to Have

Experience integrating frontends with blockchain networks using wagmi/viem, including wallet connection flows, transaction lifecycles, and Web3 UX.
