Description:

Design and implement automated testing frameworks for oracle smart contracts, including unit, integration, and end-to-end tests.
Develop and execute security test cases focusing on price data feeds, off-chain data retrieval, and multi-party consensus mechanisms.
Simulate on-chain and network abnormal conditions for stress testing and fault tolerance testing.
Collaborate with the development team for vulnerability scanning and code audits before contract deployment.
Create and maintain test documentation, defect reports, and quality assessment reports.
Verify the accuracy of oracle node data and conduct performance benchmarking.
Stay updated on blockchain testing tools and best practices, introducing new methodologies to enhance efficiency.

Requirements:

Bachelor’s degree in Computer Science, Software Engineering, or related field.
3+ years of experience in smart contract testing or development, proficient in Solidity and testing frameworks (e.g., Hardhat, Truffle, Foundry).
Deep understanding of oracle mechanisms (e.g., Chainlink, Band Protocol) and common attack vectors.
Familiarity with blockchain concepts and tools (e.g., Web3.js, Ethers.js).
Ability to develop automated testing scripts using JavaScript/TypeScript, Python, or similar languages.
Experience in security testing or code auditing preferred, with knowledge of common vulnerabilities and mitigation methods.
Strong communication skills and a collaborative mindset, adaptable to agile environments.
