Role Overview

Responsible for end-to-end quality assurance across Web and App (mobile) surfaces — combining automated and exploratory testing to ensure product stability, compatibility, and interaction experience from the user's perspective. The core requirement is cross-platform testing capability (Web + App), with the ability to design and maintain an automated testing system and to think deeply about troubleshooting and user-experience-oriented quality.

In one sentence: This role is the quality gatekeeper for Web/App products — someone who can write automation scripts, test interaction experiences, investigate data issues, and use engineering methods to replace manual testing with systematic automated quality coverage. Not a manual tester — a QA engineer with real coding ability.

Key Responsibilities

• Design and maintain comprehensive Web/App test cases and test plans covering functionality, compatibility, and interaction
• Develop and maintain UI/API automated tests using Java, Python, or JavaScript to ensure high coverage and reliability
• Combine automation and manual exploratory testing to validate user scenarios and discover potential experience issues
• Perform root cause analysis on test failures and production issues, and drive fixes to closure
• Identify blind spots in test coverage and continuously improve automation effectiveness
• Participate in testing for new features — define expected behaviors, system impact, and risk points from a user-experience perspective
• Conduct App compatibility testing across devices, OS versions, and screen sizes, as well as Web cross-browser and cross-resolution testing
• Participate in performance testing (page load time, App cold start / warm start, etc.) and ensure stability under high-concurrency and weak-network scenarios

Requirements

• Strong coding ability in at least one of Java, Python, or JavaScript (live coding assessment required)
• Extensive Web/App automation testing experience with tools such as Selenium, Appium, Playwright, etc.
• Solid understanding of Web/App testing methodologies and automation framework design
• Proficiency in SQL for data validation and issue troubleshooting
