Senior Qulaity Engineer

The Senior Quality Engineer I (SDET - Web) is responsible for ensuring the quality, reliability, and performance of Marriott's global digital web platforms through the design and implementation of scalable, maintainable automated testing solutions. This role partners closely with product, design, and engineering teams to validate complex front-end browser experiences and API integrations across a large-scale, multi-locale web ecosystem. The engineer plays a key role in advancing quality engineering practices by building robust UI and API automation, integrating tests into CI/CD pipelines, and driving a shift-left quality mindset across teams. This is a hands-on senior individual contributor role requiring strong technical depth, collaboration skills, and a passion for modern test automation.
Responsibilities:
Design, build, and maintain scalable automation frameworks for web UI and API testing using modern tools and best practices.
Develop and maintain automated browser tests for large-scale web and mobile web applications, including cross-browser and cross-device coverage.
Create, execute, and maintain automated REST and GraphQL API test suites, including functional, contract, and schema validation.
Foster an AI-first culture within the team and leverage GenAI-based tools (such as ChatGPT, Claude, or similar) to execute technical tasks, including component development, QA automation, and workflow optimisation.
Integrate UI and API test suites into CI/CD pipelines to support continuous testing and high-quality releases.
Partner with developers, product owners, and QE leads to ensure testability, clear acceptance criteria, and comprehensive quality coverage.
Perform root cause analysis on defects and collaborate with engineering teams to validate fixes.
Implement regression, visual validation, and accessibility testing to reduce manual testing effort and improve coverage.
Drive shift-left quality engineering practices and provide technical guidance and mentoring to other QE and SDET team members.
Improve automation reporting, test data management, and environment readiness.
Own automation quality for one or more major web domains or platforms.
Contribute to Quality Engineering Centre of Excellence (COE) standards, reusable frameworks, and shared testing accelerators.
Requirements:
Bachelor's degree in Computer Science, Engineering, or equivalent practical experience.
5+ years of experience in software quality engineering with a strong focus on web and API automation.
Hands-on experience with modern test automation frameworks and tools, including: Selenium WebDriver with Java and TestNG or JUnit, Playwright with JavaScript or TypeScript, BrowserStack or similar cloud-based cross-browser testing platforms, REST API testing tools such as Postman, REST Assured, ReadyAPI or equivalent, and GraphQL API testing, including queries, mutations, and schema validation
Strong programming skills in Java, JavaScript/TypeScript, or Python.
Solid understanding of HTML5 CSS3 DOM, browser behaviour, and developer tools.
Exposure to agentic GenAI development tools like Claude, ChatGPT, or other tools.
Experience integrating automated tests into CI/CD pipelines using tools such as Jenkins, GitHub Actions, Harness, or equivalent.
Proven ability to design and execute complex testing strategies beyond basic functional testing.
Strong debugging, problem-solving, and analytical skills.
Experience working in fast-paced Agile/Scrum environments.
Excellent communication and collaboration skills.
Familiarity with API mocking and service virtualisation tools (e. g., WireMock, MSW).
Experience with containerised or distributed test execution environments (Docker, Kubernetes).
Experience testing microservices and distributed systems.
Experience with AI-assisted development or testing tools (e. g., GitHub Copilot, Cursor) to improve automation development productivity.
Experience testing AI-enabled web or API-based applications is a plus.
Knowledge of Marriott digital platforms or prior experience in hospitality, travel, or e-commerce domains is a plus.
