Familiarity with Kubernetes platforms, containerized workloads, and infrastructure-level software components sufficient to write technically meaningful tests — not just UI-level validation, but tests that verify scheduling behavior, resource allocation, tenant isolation enforcement, storage mount integrity, and platform service availability under load. - Experience designing and executing systematic test campaigns for complex, multi-component software platforms — including writing unit tests, integration tests, and end-to-end system tests against documented requirements in environments where the test infrastructure must be built alongside the system under test.
