About the Role

We are looking for a Senior QA Automation Engineer to own quality strategy for serverless middleware services powering ordering, loyalty, payments, and third‑party integrations across a major consumer platform. You will design and maintain automated test suites for RESTful APIs and event‑driven architectures on AWS, execute performance and load testing, validate partner integrations including delivery and payment platforms, and integrate quality gates into CI/CD pipelines using Azure DevOps and GitHub Actions. The role expects active use of AI‑assisted tools as a core part of daily quality engineering work.

• Validate event‑driven workflows and asynchronous messaging;
• Execute performance and load testing;
• Validate resiliency and failure scenarios;
• Design, build, and maintain automated test suites covering functional, integration, and contract testing for middleware APIs and services ensuring correct behavior in isolation and across dependencies;
• Leverage AI‑assisted tools for test case generation, synthetic data creation, failure analysis, and coverage documentation;
• Own performance and reliability validation including load, stress, spike, and soak testing, establishing baselines and identifying bottlenecks;
• Partner with engineers throughout the development cycle to align on test strategy, acceptance criteria, and CI/CD integration via Azure DevOps or GitHub Actions;
• Validate third‑party integrations through contract testing, sandbox/staging validation, and failure mode analysis;
• Track and report quality metrics, maintain documentation, and contribute to incident post‑mortems.
