Test Automation Engineer in City of Westminster

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 generation, 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's 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 preferred; 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.
