Senior QA Automation Engineer

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.

What you will do

• Build automated test frameworks for serverless applications;
• 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.

Must haves

• 4+ years of quality engineering or software engineering experience focused on backend API testing;
• Experience designing automated test suites for REST APIs in distributed or microservices environments;
• Hands-on experience with performance and load testing;
• Proficiency in JavaScript/TypeScript, Java, or Python;
• Working knowledge of AWS serverless services (Lambda, API Gateway, DynamoDB, SQS/SNS);
• Experience integrating automated tests into CI/CD pipelines (Azure DevOps, GitHub Actions);
• Proficiency with AI-assisted development tools (GitHub Copilot, Claude, or equivalent);
• Familiarity with contract testing approaches and consumer-driven contracts;
• Strong analytical and root-cause analysis skills, including distinguishing flaky tests from real defects;
• Experience validating asynchronous systems;
• Strong scripting skills;
• Clear communication and ability to translate test findings into engineering priorities;
• Collaborative approach to working within engineering sprints;
• Upper-intermediate English level.

Nice to haves

• Experience with k6, Gatling, JMeter, or similar performance testing tools;
• Postman/Newman experience;
• Familiarity with Pact or other contract testing tools;
• Cognito authentication testing experience;
• Delivery and payment integration testing experience;
• Experience with DoorDash, Uber Eats, or similar marketplace APIs;
• Chaos engineering and fault injection (AWS FIS or similar);
• Observability tooling experience (Dynatrace, Datadog, CloudWatch);
• Multi-region AWS testing and failover/latency validation;
• Background in QSR, retail, or e-commerce domains;
• AWS Certified Developer – Associate or higher.
