1. Responsible for writing, reviewing, and executing functional test cases for the iterative development of the backend systems, official website, DApp, and mobile APP in Web3 projects, ensuring stable front-end and back-end coordination across all platforms;

2. Independently complete interface testing for both on-chain and off-chain systems, including test case design, execution, and issue regression for scenarios such as on-chain transaction calls, wallet authorization, Token transfers, and contract invocations;

3. Write and maintain automated test scripts suitable for Web and App, covering UI automation (Selenium/Appium) and API automation (Python + Requests), and adapt testing for multi-chain wallet connections (e.g., MetaMask, Phantom, OKX Wallet);

4. Assist the development and product teams in troubleshooting online issues in Web3 projects on a daily basis, including typical problems such as wallet connection failures, on-chain transaction anomalies, Gas calculation errors, and Token non-receipt;

5. Participate in issue tracking and continuous improvement after product launch, collect on-chain/off-chain exception logs and user feedback, and promote optimization and fixes for DApp or backend services;

6. Regularly execute centralized regression testing tasks, covering backend, frontend, DApp, wallet authorization, and other modules, with a focus on the impact of new features on on-chain interactions and the accuracy of data synchronization.

1. Familiarity with the basic architecture of Web3/DApp products and blockchain interaction logic, possessing comprehensive experience in software testing processes, and being able to independently write test plans, cases, reports, and other testing documentation;

2. Proficient in using tools such as Chrome F12/Fiddler/Postman for packet capturing and locating on-chain and off-chain interface issues;

3. Familiar with defect management processes, skilled in using tools like JIRA for defect submission, tracking, and management;

4. Proficient in using MySQL and common Linux commands, able to assist in verifying the consistency of off-chain database data with on-chain data;

5. Familiar with performance testing processes, understanding on-chain transaction performance indicators (such as transaction confirmation delay, throughput, transaction failure rate, etc.) and capable of designing and executing performance scripts;

6. Able to write UI automation scripts for web applications, adapting to complex interactions such as wallet authorization pop-ups and multi-wallet switching in DApps;

7. Capable of conducting UI automation testing for mobile Web3 applications, including processes for multi-chain wallet interactions, transfer authorizations, and on-chain asset displays;

8. Bonus points: Understanding EVM contract calls, familiarity with the multi-chain interaction logic of Solana/TON/BSC, and preference for candidates with experience in contract testing or security testing.
