Senior QA Engineer

About the role

We are looking for a Senior QA Engineer to own automation quality for a global QSR brand’s customer-facing web platforms built on React and Next.js. You will develop and maintain automated test suites using Cypress and Jest, validate AEM headless content delivery, execute cross-browser testing via BrowserStack, and integrate quality gates into CI/CD pipelines through GitHub Actions. The role spans functional, accessibility, and performance testing with attention to Core Web Vitals and ADA/WCAG compliance.

What you will do

• Develop and execute test plans and test cases for React/Next.js web applications across desktop and mobile browsers;
• Perform manual and automated testing to validate functionality, UI/UX, performance, and cross-browser compatibility;
• Build and maintain automated test suites using Cypress for end-to-end flows, Jest and React Testing Library for unit and component coverage, and real-browser validation via BrowserStack or Sauce Labs;
• Validate integration and content rendering within Adobe Experience Manager (AEM) Sites CMS, including headless content delivery and personalization surfaces;
• Collaborate with cross-functional teams — developers, product managers, and designers — to define test requirements and ensure testability and accessibility of features (including ADA/WCAG compliance);
• Analyze test results, identify root causes of failures, and work closely with developers to drive resolution;
• Identify, document, and track bugs and issues in Azure DevOps; monitor open defects through to closure;
• Monitor app performance and user feedback signals (Quantum Metric, Sentry) proactively identify quality improvements;
• Help keep CI/CD quality gates healthy: automated test runs, build validation, and deployment pipelines via GitHub Actions;
• Write and maintain test documentation — test plans, test cases, coverage maps — and contribute to architecture decision records where testing strategy is relevant;
• Participate in Agile ceremonies: standups, sprint planning, refinement, and retrospectives;
• Stay current with the React and web testing ecosystem and contribute to team-wide quality improvements, including ongoing AEM content platform evolution.

Must haves

• +4 years of professional web QA experience, with at least 1 year focused on React applications;
• Strong understanding of web technologies including HTML, CSS, JavaScript, and React;
• Hands-on experience with Cypress or Playwright for end-to-end testing;
• Experience with automated testing frameworks: Jest, React Testing Library, or equivalent;
• Familiarity with CI/CD tools (e.g., GitHub Actions, Jenkins) and version control (Git);
• Experience with cloud-based browser testing platforms (e.g., BrowserStack, Sauce Labs);
• Experience testing web applications built on Adobe Experience Manager (AEM) Sites CMS;
• Knowledge of web analytics and error monitoring tools (e.g., Quantum Metric, Sentry, Google Analytics);
• Basic understanding of TypeScript and React architecture;
• Clear communicator who works well in a collaborative, cross-functional team;
• Upper-intermediate English level.

Nice to haves

• Experience testing payment integrations (Adyen, Apple Pay, Google Pay) in a web context;
• Familiarity with feature flag systems (e.g., LaunchDarkly) and testing flag-gated features;
• Exposure to mobile analytics platforms (Adobe Experience Platform, Quantum Metric);
• ADA/accessibility testing experience and familiarity with WCAG standards;
• Performance testing — Core Web Vitals, time-to-interactive, and Lighthouse audits;
• Internationalization (i18n) and multi-language web app testing;
• Experience with headless CMS architectures and content-driven web applications.
