Job Description
We’re looking for an experienced web quality engineer to help ensure web and e-commerce experience meets the highest standards of performance, reliability, and user experience — the digital storefront millions of guests use to order food, manage their loyalty rewards, find nearby restaurants, and check out with their preferred payment method.
You’ll work in a collaborative product team alongside developers, product managers, and designers, championing quality throughout the development lifecycle. Testing coverage, automation depth, and accessibility compliance are core priorities: every release is expected to maintain the seamless cross-platform web experience our guests expect.

WHAT YOU’LL 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 our 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 our ongoing AEM content platform evolution.

Requirements (MUST-HAVE)

• 3–5 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.
• Bachelor’s degree in Computer Science, Engineering, or a related field — or equivalent hands-on experience.

Nice to have: 

• 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
