1. Job Responsibilities:

- Development of test cases and API concurrency stress testing;

- Writing and maintaining automated test cases for smart contracts, covering scenarios such as functionality, boundaries, exceptions, and attack vectors;

2. Test Platform Setup

- Building contract testing frameworks and CI/CD testing platforms based on tools like Hardhat / Foundry, achieving automated construction, deployment, testing, and regression;

3. Fuzz & Security Testing

- Writing Fuzz tests and integrating static analysis tools (such as Slither, Mythril) to uncover contract vulnerabilities and operational boundaries;

4. On-chain Simulation Testing

Constructing on-chain fork testing environments to simulate real user and fund flow testing (mainnet fork or testnet simulation);

5. Script Development

- Writing TypeScript/Python scripts to simulate contract invocation processes, batch deployment, state tracking, and on-chain verification;

6. Testing Monitoring

- Integrating with platforms like Tenderly/Forta/Graph to continuously monitor on-chain contract behavior and performance metrics;
