Job Responsibilities

Design and Develop Core Trading Interface: Responsible for the design, development, and maintenance of the core user interface of the DEX platform, including but not limited to essential functional modules such as token exchange, liquidity pool management, transaction history, and asset management, ensuring high performance, high responsiveness, and an exceptional user experience.

Deep Integration of Web3 Technology Stack: Proficiently integrate mainstream Web3 libraries (such as ethers.js / web3.js, wagmi) with user wallets (such as MetaMask, WalletConnect, Coinbase Wallet, etc.), to achieve secure wallet connections, transaction signing, status listening, and on-chain interactions.

Real-time Display and Interaction of On-chain Data: Implement real-time acquisition, parsing, and visualization of on-chain data (such as price charts, depth charts, gas fee estimates, transaction status updates) and facilitate secure user interaction with smart contracts.

Optimizing Frontend Performance and Security: Have a deep understanding of the performance bottlenecks in blockchain applications (such as RPC call optimization, state update management) and continuously optimize frontend performance. Strictly adhere to security best practices, writing robust and secure code to prevent frontend-level attacks (such as phishing, state manipulation).

State Management and Complex Interaction Logic: Efficiently manage complex application state using modern state management solutions (such as Redux, Zustand, MobX, Context API + Hooks), handling asynchronous operations and transaction processes.

Responsive and Multi-end Adaptation: Ensure that the DEX platform provides a consistent and excellent user experience on both desktop and mobile (Web) platforms.

Collaboration and Quality Assurance: Work closely with UI/UX designers to implement design drafts. Collaborate efficiently with smart contract developers and backend engineers to define interface specifications. Write high-quality, maintainable code and develop unit tests and integration tests (such as Jest, React Testing Library, Cypress) to ensure frontend quality.

Technical Exploration and Documentation: Stay updated on the development trends of Web3 frontend technologies, evaluate and introduce appropriate new technologies. Write clear technical documentation.
