Job Description
1. Smart Contract Interaction Service Development
- Design and implement high-reliability, low-latency Java services for interacting with smart contracts on EVM-compatible chains (e.g., Ethereum, BNB Chain, Arbitrum), including function calls, event listening, and state synchronization.
- Encapsulate on-chain operations for core business processes such as multi-chain asset deposits, withdrawals, and transfers.
2. Simulation → Live System Evolution Support
- Optimize existing simulation backend logic to ensure its behavior aligns closely with future live trading systems.
- Participate in stress testing, fault drills, and canary release planning prior to live system deployment.
3. Asset & Order System Integration
- Collaborate closely with matching engines, account systems, and risk control modules to ensure data consistency between contract and application layers.
- Implement critical mechanisms including asset snapshots, balance verification, and exception rollback.
4. Security & High Availability Assurance
- Adhere to Web3 security best practices (e.g., private key management, replay attack prevention, Gas optimization).
- Build monitoring and alerting systems for real-time response to anomalies like failed transactions or block delays.
5. Technical Documentation & Collaboration
- Produce clear technical design documents and API specifications.
- Assist QA team in developing automated test cases for contract interactions.
Job Requirements
- 5+ years of Java backend development experience with proficiency in Spring Boot, MyBatis, Redis, and MySQL.
- Solid understanding of Web3 fundamentals: wallets, private keys, Gas, ABI, EVM, and event logs.
- Hands-on experience with smart contract interactions.
- Understanding of blockchain node operations (e.g., Geth, Infura, Alchemy).
- Strong capabilities in concurrency handling, transaction management, and exception recovery.
