About the job
As a Smart Contract Quality Assurance Engineer specializing in Oracle technologies, you will be pivotal in maintaining the integrity and security of our smart contract ecosystem. Your core responsibilities will include:
- Crafting and implementing automated testing frameworks specifically tailored for Oracle smart contracts, encompassing unit tests, integration tests, and comprehensive end-to-end testing.
- Creating and executing security test cases targeting critical scenarios such as price data feeds, off-chain data retrieval, multi-party consensus mechanisms, and resistance to Sybil attacks.
- Simulating various on-chain and network irregularities (e.g., high gas fees, network latency, node failures) to conduct stress testing and evaluate fault tolerance.
- Collaborating closely with the development team to perform vulnerability scans and assist in code audits prior to contract deployment, ensuring the absence of critical security threats.
- Producing and maintaining comprehensive documentation for tests, defect reports, and quality assessments.
- Engaging in the verification of oracle node data accuracy and conducting performance benchmarks.
- Staying updated with blockchain testing tools and best practices while proposing innovative testing methodologies to improve efficiency.
