About Symbiotic

Symbiotic is the infrastructure beneath collateral markets, where capital can secure financial obligations, remain productive, and be enforced by code.

By changing the economics of onchain collateral, Symbiotic enables new categories of neofinance applications that were previously impossible to build - including credit, insurance, RWA liquidity, and more.

As institutional capital increasingly moves onchain, Symbiotic is positioned to become the coordination layer connecting capital and risk across the onchain economy.

Backed by Paradigm, Pantera, Cyber.fund, and Coinbase Ventures, we power 80+ vaults, 74,000+ active stakers, and 111 operators - with Chainlink, Nexus Mutual, and Cap Labs among the teams live in production.

See how Symbiotic is powering the next generation of onchain finance: symbiotic.fi

Our People

We’re a tight-knit team of experienced builders working at the forefront of financial infrastructure. Our backgrounds span high-growth tech start-ups, leading crypto companies, major banks, insurers, and financial institutions. We work with ownership, a high bar for craft, and the urgency of an early-stage company - in an environment where people are trusted to take initiative and supported to do their best work.

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

What You'll Do

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.

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 (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
