Role Overview: Are you passionate about Test Automation and building robust frameworks? We are seeking a Test Automation Expert to lead and evolve our testing framework for WeChat Mini Program apps. You\'ll work on a high-impact initiative that drives automated test creation and execution inside Weixin DevTools while exploring innovative approaches (including functional agents) to speed up authoring, maintenance, and reliability. You\'ll work closely with a supportive team focused on quality at scale, engineering excellence, and continuous improvement. Along the way, you\'ll gain hands-on experience with modern JavaScript tooling, multi-platform automation, and end-to-end CI/CD practices. This role offers strong long-term growth, giving you ownership over the framework\'s direction, best practices, and meaningful innovation in the test automation space.

Responsibilities

• Collaborate with the project lead to enhance and scale our Testing Framework for Weixin DevTools (WeChat Mini Program E2E and regression testing)
• Design and develop JavaScript/TypeScript modules, utilities, and helpers for test authoring, data management, and execution
• Integrate and optimize third-party tools for orchestration and evaluation (e.g., WebdriverIO, Selenium, Appium), including parallelization and CI/CD pipelines
• Define and support QA testing phases (smoke, regression, integration, E2E, UAT) and implement best practices in test design and maintainability
• Build reusable patterns (page objects/screenplay), selectors, fixtures, and stubs/mocks to stabilize and scale the test suite
• Introduce innovations to accelerate testing such as functional agents for code, smart selectors, self-healing locators, and automated test data strategies
• Contribute to metrics and reporting: coverage, stability, flakiness rate, pass/fail trends, and time-to-detect/repair
• Support continuous validation, experimentation, and automation throughout development cycles; mentor contributors to the framework

About the candidate

• A minimum Bachelor\u2019s degree in Computer Science or a technology-related field
• Strong expertise in JavaScript (and ideally TypeScript) with solid Node.js fundamentals
• Hands-on experience with test automation frameworks and tools; knowledge of WebdriverIO; Appium and Selenium are welcomed
• Proven QA tester background with understanding of testing phases, test design techniques (e.g., equivalence partitioning, boundary values), and defect lifecycle
• Experience building or maintaining automation frameworks, including utilities for data management, reporting, and CI integration
• Familiarity with mobile or mini-program testing; exposure to Weixin DevTools or the WeChat Mini Program ecosystem is a strong plus
• Comfort with asynchronous programming, selectors strategy, network interception/mocking, and flaky test mitigation
• Curiosity, autonomy, and a collaborative mindset especially on exploratory and framework-level initiatives
