• Test integrations between the storefront and catalog, pricing, inventory, order, payment, and delivery services, as well as external grocery partners.
• Validate fallback and degradation scenarios when a partner or internal service is unavailable.
• Ensure consistent behavior across mobile applications, WebView, and backend APIs.
• Develop and maintain automated tests and contribute to API, integration, and end-to-end test coverage.
• Participate in requirements reviews, test strategy, release validation, and investigation of production issues, taking ownership of quality throughout the product lifecycle.

• Experience with grocery/e-commerce products
• Experience testing dynamic pricing, inventory, discounts, product availability, quantity limits, and minimum order value.
• Good understanding of grocery-specific scenarios, such as weighted products, substitutions, unavailable items, and partial orders.
• Experience testing integrations with catalog, pricing, inventory, order, payment, and delivery services, including third-party partner APIs.
• Experience with REST and/or gRPC APIs and automated API testing; familiarity with tools such as Postman.
• Experience creating and maintaining automated tests using frameworks such as Playwright, Cypress, Appium, or similar.
• Ability to validate consistency across mobile applications, WebView, backend APIs, and distributed services, and troubleshoot partial failures and partner/service outages.

Nice to have: contract testing, external partner integrations, performance/load/resilience testing, feature flags, A/B testing, and product metrics such as conversion, add-to-cart rate, checkout completion, error rate, and latency.
