Job Description
We are seeking a skilled Blockchain Developer to join our team. The ideal candidate will be responsible for designing and developing core blockchain modules and sidechain services. This role involves working on smart contract interaction layers, P2P network layers, and transaction packaging/broadcasting logic. You will optimize critical functions like transaction signing, Nonce management, block packaging, and consensus message processing. Collaboration with the smart contract team is essential to ensure on-chain/off-chain data consistency, event monitoring, and state aggregation. Additionally, you'll implement high-performance RPC/message queue services, conduct performance analysis, and write comprehensive unit/integration tests to ensure system security and stability. The role also requires continuous improvement of monitoring, logging, and alerting systems to promptly address chain anomalies and reorganization events.
