As an Automation QA Engineer, you'll design and implement test frameworks for Oracle projects, focusing on automation testing for APIs and web interfaces, collaborating with development teams to identify and resolve defects.
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.
Requirements:
- 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.
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 GitHub or demonstrable testing case portfolios.
