Job Responsibilities

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).
