Job Description

Key Responsibilities

• Lead the design and implementation of Navi Protocol’s DEX aggregator, with a focus on React-based frontends and Node.js/TypeScript backends, optimizing liquidity routing, price aggregation, and cross-exchange transaction flows.
• Collaborate with in-office and remote team members—including product managers, blockchain engineers, and UI/UX designers—to integrate new DEX partners and enhance platform functionality.
• Develop responsive, low-latency React UIs that deliver real-time price comparisons, transaction simulations, and intuitive trading experiences for users.
• Build and maintain Node.js/TypeScript backend services, including liquidity aggregation algorithms, API integrations with partner DEXs, and transaction routing logic.
• Optimize smart contract interactions (e.g., multi-step swaps, gas estimation) to ensure cost-efficiency and reliability across EVM and non-EVM chains.
• Troubleshoot cross-stack issues, from React frontend state management to Node.js/TypeScript backend performance and blockchain transaction execution.
• Drive innovation in DEX aggregation, such as refining routing efficiency, reducing slippage, and enhancing user trust through transparent transaction mechanics.
• Mentor junior engineers in React/Node.js best practices, conduct code reviews, and enforce standards for maintainable, secure code.

Required Qualifications

• 5+ years of full stack engineering experience, with 2+ years specializing in DEX aggregators or decentralized trading platforms.
• Expertise in Node.js and TypeScript for backend development, including RESTful API design, WebSocket integration, and performance optimization.
• Advanced proficiency in React for frontend development, with experience in state management (Redux, Context API), component architecture, and responsive design.
• Deep understanding of DEX aggregator mechanics: liquidity routing algorithms, price aggregation logic, and cross-exchange compatibility.
• Strong knowledge of blockchain fundamentals, including smart contracts (Solidity/Rust/Move), EVM chains, and layer-2 solutions (e.g., Arbitrum, zkSync).
• Experience with blockchain development tools: Ethers.js, Web3.js, Hardhat, and integration with DEX APIs (e.g., Uniswap, SushiSwap, PancakeSwap).
• Familiarity with security practices for DEX aggregators, including front-running mitigation, transaction validation, and smart contract interaction auditing.
• Ability to thrive in a fast-paced environment, adapting to evolving DeFi protocols and Navi Protocol’s roadmap.
• Eligibility to work in the United States and willingness to participate in a hybrid work model in the Bay Area.
• Bachelor’s degree in Computer Science, Engineering, or equivalent practical experience.

Preferred Qualifications

• Direct experience building or scaling DEX aggregators (e.g., 1Inch, Matcha, 0x Protocol).
• Familiarity with cross-chain aggregation technologies and bridge integrations.
• Experience with DevOps for Node.js/React applications (CI/CD, Docker, AWS/Azure, monitoring tools like Datadog).
• Contributions to open-source DeFi or React/Node.js projects.
• Highly preferred: Experience with Sui blockchain development and on-chain integrations.
• Understanding of yield optimization or advanced trading features (e.g., limit orders, TWAP).
