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.
