Understanding of modern Quality Engineering practices, including test automation, API testing, CI/CD, performance testing, observability, and integration testing tools such as Playwright, Postman, Rest Assured, GitHub Actions, Azure DevOps, Jenkins, JMeter, K6, Gatling, SonarQube, Splunk, Dynatrace, Datadog, and MuleSoft. More important than deep expertise in specific tools is the ability to develop and lead an automated, risk-based quality strategy integrated throughout the software delivery lifecycle and an understanding of operating systems, hardware interaction, or platform services.
