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) to 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.
