Job Description
Core Responsibilities:
• Design and implement automated testing frameworks for oracle smart contracts, covering unit tests, integration tests, and end-to-end tests
• Develop and execute security test cases, focusing on core scenarios such as price data feeds, off-chain data retrieval, multi-party consensus mechanisms, and resistance to Sybil attacks
• Simulate various on-chain and network abnormal conditions (e.g., high Gas fees, network latency, node failures) to conduct stress testing and fault tolerance testing
• Work closely with the development team to perform vulnerability scanning and assist in code audits before contract deployment, ensuring no critical security risks
• Create and maintain clear test documentation, defect reports, and quality assessment reports
• Participate in verifying the accuracy of oracle node data and conducting performance benchmarking
Continuously follow blockchain testing tools and best practices, and introduce new testing methodologies to enhance efficiency

• 3+ years of experience in smart contract testing or development, with proficiency in Solidity and mainstream testing frameworks (e.g., Hardhat, Truffle, Foundry)
• Deep understanding of oracle mechanisms (e.g., Chainlink, Band Protocol) and awareness of common attack vectors (e.g., flash loan attacks, data tampering)
• Familiar with fundamental blockchain concepts (consensus mechanisms, Gas optimization, event logs, etc.) and tools (e.g., Web
3.js, Ethers.js)
• Capable of developing automated testing scripts using JavaScript/Type Script, Python, or similar languages
• Experience in security testing or code auditing is preferred, with knowledge of common vulnerabilities (e.g., reentrancy, integer overflow) and mitigation methods
Strong communication skills and a collaborative mindset, adaptable to agile development environments
•
Preferred Qualifications:
• Hands-on experience in testing or developing oracle projects, with familiarity in decentralized data sources and node networks
• Knowledge of zero-knowledge proofs, TEE (Trusted Execution Environment), and other privacy-related oracle technologies
• Experience with performance testing tools (e.g., K6, Gatling) or on-chain monitoring tool development
• Open-source contributions to blockchain projects on Git Hub or demonstrable testing case portfolios
