Web 3 Full-Stack Developer

Web 3 Full-Stack Developer Employment: Full-time Location: Hong Kong

1. Frontend Development -Build streaming DApp frontends using React/Vue3, integrating Web3Modal to support multi-wallet login. -Develop TVOS interfaces: use the Enact framework (WebOS) or Leanback library (Android TV) to display on-chain content. 2. Backend Middleware -Set up Node.js middleware to handle video metadata on-chain operations (e.g., IPFS CID generation) and store ad click event logs. -Design high-concurrency architectures: use Redis caching to accelerate on-chain data queries (e.g., user token balances). 3. Off-Chain Services -Develop off-chain computation tasks: dynamically adjust video bitrate based on blockchain storage costs using AWS Lambda. -Integrate with decentralized storage: implement automatic scaling for IPFS clusters triggered by video upload volume. 4. On-Chain Services -Develop smart contract wallets: implement wallets based on ERC-4337/EIP-6551 standards, supporting basic wallet functionalities. -NFT & DeFi development: create trading pools for NFT-Token/Token-Token pairs and monitor pool liquidity. -Contract deployment and upgrades: provide upgrade functionality for all deployed contracts, supporting single or batch upgrades for specified contracts. -Contract interaction interfaces: encapsulate contract interaction APIs to ensure consistent interface calls. Job Requirements -Experience: At least 3 years of experience as a full-stack developer, with at least one live blockchain DApp project (preferably in streaming media/digital content). Experience with TVOS app store deployments (provide package name/download link) is a plus. -Decentralized Streaming Protocols: Experience in the ecosystem development of decentralized streaming protocols (e.g., LivePeer/Theta). -Frontend Development: Proficiency in React/Vue3 + TypeScript, with experience in complex state management (e.g., Redux/Pinia). Familiarity with multi-wallet integration solutions like Web3Modal or Web3-Onboard. -Backend Development: Skilled in Node.js (NestJS/Express) for high-concurrency services, designing REST/GraphQL APIs to bridge on-chain and off-chain data. Expertise in Redis caching strategies (e.g., preventing cache penetration/avalanche) to accelerate on-chain data queries. -Smart Contract Interaction: Proficiency in ethers.js/web3.js for smart contract interaction. Experience in developing The Graph subgraphs (indexing on-chain events) and handling IPFS file uploads/retrievals (generating CIDs and storing metadata). -Smart Contract Development: Expertise in Solidity smart contract development and testing, capable of independently handling complex interaction scenarios (preferred). -NFT & Wallet Protocols: Familiarity with NFT standards, EIP wallet-related protocols, and DeFi protocols (preferred). -Blockchain Security: Knowledge of blockchain security, capable of testing contract security and preparing risk assessment reports (bonus). ‍ Contact Apply now including your resume and salary expectations via email to [email protected]
