Senior Fullstack QA Engineer (Grocery)

The Grocery Team is responsible for building and evolving the customer experience for grocery delivery — from discovering stores and products to browsing the catalog, managing the cart, and completing checkout. We’re looking for a QA Engineer to join our team

Test the full grocery customer journey, including store selection, catalog, search, product details, cart, checkout, payment, and order creation.
Validate prices, discounts, inventory, product availability, and store-specific assortment across different locations and partners.
Test grocery-specific scenarios such as weighted products, substitutions, unavailable items, quantity limits, and minimum order values.
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.
