Senior Front-End Engineer

Role Description

We’re looking for talented professionals to join us at a defining moment, as Symbiotic helps shape the next generation of onchain finance.

• Participate in all phases of frontend development: requirements analysis, architecture and design, implementation, documentation, testing, and delivery.
• Build responsive and accessible user interfaces based on Figma designs.
• Prototype interfaces for testing MVPs.
• Develop reusable components and maintain them in Storybook.
• Integrate new features into the existing codebase.
• Implement blockchain and wallet interactions.
• Design efficient approaches to client-side state management, server-state synchronization, caching, and error handling.
• Write unit, integration, and end-to-end tests.
• Monitor production issues and application performance using Sentry.
• Contribute to project estimation, planning, and technical decision-making.
• Review code written by other team members and help maintain engineering standards.
• Communicate effectively with engineers, designers, product stakeholders, and company partners.

Qualifications

• 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 (TanStack Query), lightweight client state (Zustand or similar), and when to use which.
• Strong CSS and responsive design fundamentals; experience with component libraries such as Chakra UI.
• Able to turn Figma designs into accessible, reusable components, ideally documented in Storybook.
• Solid testing practice across unit, integration, and E2E (Vitest, Playwright), including async and wallet-interaction flows.
• Able to optimize performance (code splitting, memoization, bundle analysis, Core Web Vitals) and debug production issues with tools like Sentry.
• Security-conscious: CSP, secure wallet interactions, input validation, and safe handling of secrets.
• Confident with Git workflows, Docker, and GitHub CI/CD; basic familiarity with Kubernetes and CDNs.
• Nice to have: experience integrating frontends with blockchain networks — wagmi/viem, wallet connection flows, transaction lifecycles, and Web3 UX.
