- Log, prioritize, and validate defect fixes using Azure DevOps/Jira; provide clear reproduction steps and supporting evidence
- Create deterministic test data, stubs/mocks, and environment configurations; manage secrets securely and ensure test repeatability
- Maintain living test plans, suites, and dashboards; publish sprint quality reports and release readiness summaries
- Integrate tests into CI/CD pipelines (Azure DevOps/GitHub Actions) and contribute to pull-request quality gates (coverage, static analysis, linting)
- Author test runners and Docker files; execute suites inside Docker and assist with Kubernetes job orchestration for parallel test runs
- Capture structured logs and traces (OpenTelemetry/App Insights), triage failures, and support root-cause analysis with engineers

- Exposure to MuleSoft Anypoint Platform or other enterprise integration testing
- Exposure to containerized test execution (Docker, Kubernetes)
- Exposure to observability tooling (OpenTelemetry, App Insights)
- Strong analytical and problem-solving skills with the ability to triage complex failures and drive root-cause analysis
