• Develop API testing strategies for distributed systems (REST/GraphQL)
• Collaborate with developers to embed testing into the CI/CD pipeline (GitLab + Harness)
• Validate deployments in Kubernetes (EKS) environments
• Implement test data management and environment strategies
• Drive shift-left testing practices and improve test coverage early in development
• Perform root cause analysis on failures across services and pipelines
• Contribute to performance, scalability, and reliability testing initiatives
• Continuously improve testing frameworks, tooling, and processes
