ABOUT THE ROLE
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.

TECH AT A GLANCE
Our web QE stack in plain terms:
Area & Details
Framework: React (Next.js) — SSR/SSG web app
Language: TypeScript (strict mode) — strongly typed throughout
Unit / Component: Jest, React Testing Library
End-to-End: Cypress (primary), Playwright
Cross-Browser Testing: BrowserStack, Sauce Labs (real browser clouds)
CI/CD: GitHub Actions, Vercel / custom pipeline
Bug Tracking: Azure DevOps
Crash / Error Reporting: Sentry
Analytics: Adobe Experience Platform, Quantum Metric
CMS: Adobe Experience Manager (AEM) Sites — headless & traditional
Feature Flags: LaunchDarkly (controls which features are live for which users)
Auth: AWS Cognito (token-based login/session management)

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.

WHAT WE’RE LOOKING FOR
Required:
• 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.

HOW WE WORK
We use Agile delivery in two-week sprints, tracked in Azure DevOps. Design specs come from Figma. Architecture decisions and technical docs live alongside the code in the repository. We value test coverage, thoughtful automation strategy, and incremental improvement over big-bang rewrites.
Pull requests go through automated CI checks (tests, linting, build validation) and at least one peer review before merging. We treat the CI pipeline as a quality gate, not a formality — and QE owns a critical piece of that gate.
