Role Description - 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. Qualifications - Bachelor’s degree or higher in Computer Science, Software Engineering, or a related field. - 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., Web3.js, Ethers.js). - Capable of developing automated testing scripts using JavaScript/TypeScript, 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. Requirements - 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 GitHub or demonstrable testing case portfolios.

• Design, create and implement an automation framework from scratch. • Evaluate and recommend the starting automation toolset (Selenium With Java). • Execute functional, integration and regression testing plans and scripts. • Work closely with engineers and product owners locally. • Log, track and document bugs discovered during testing as well as gather all necessary information. • Perform regression, installation, and upgrade testing in every release cycle.
