Senior Fullstack QA Engineer

About the job

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.

• Strong experience in functional, integration, API, and end-to-end testing across the full customer journey: catalog, search, PDP, cart, checkout, payment, and order creation.
• Experience testing dynamic pricing, inventory, discounts, product availability, quantity limits, and minimum order value.
• Experience testing location- or store-specific assortment, including warehouse and geo-based availability.
• 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.
• Strong understanding of microservices, event-driven and asynchronous architectures, including retries, timeouts, idempotency, duplicate events, and eventual consistency.
• 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 investigate issues using logs, metrics, traces, databases, and message queues; experience with tools such as Grafana, CloudWatch, Kibana, Kafka, and SQL.
• Experience working with CI/CD pipelines, Docker, and AWS-based environments.
• Ability to validate consistency across mobile applications, WebView, backend APIs, and distributed services, and troubleshoot partial failures and partner/service outages.
• Experience contributing to test strategy, requirements reviews, release validation, and production issue analysis, with a focus on business risks and product quality throughout the entire development lifecycle.

Nice to have: experience with grocery/e-commerce products, mobile testing, 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.
