Role Overview
Test Automation Engineer
About the organisation:
The organisation is a QA and software testing company focused on delivering high-quality digital solutions. We provide governance and production monitoring to ensure ongoing performance and compliance after release. Through advanced test automation and AI-driven testing strategies, we help organizations accelerate development, reduce risk and ensure reliability across the entire software lifecycle. Our goal is to transform QA into a strategic driver of innovation and efficiency.
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 messaging mini-application platform apps. You'll work on a high-impact initiative that drives automated test creation and execution inside mini-application development tools-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.

Key Responsibilities
• Collaborate with the project lead to enhance and scale our Testing Framework for mini-application development tools (messaging mini-application platform 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, test automation framework, mobile test automation framework), 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 server-side JavaScript runtime fundamentals.
• Hands-on experience with test automation frameworks and tools; knowledge of WebdriverIO preferred; mobile test automation framework and test automation framework 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 mini-application development tools or the messaging mini-application platform 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 the organisation is an Equal Opportunities Employer and committed to embracing diversity in the workplace.
