Partner with QA to build the reproducible test fleet and deployment test harness that proves a release works across the Kubernetes distributions, identity providers, and version states our customers actually run, and that produces our published compatibility matrix as a by-product rather than as a document somebody maintains by hand. You'll build and maintain a compatibility matrix customers can self service without engineering support, build automation to test and validate releases for deployability before they ship rather than after, and architect and deliver observability and diagnostics a customer can run and act on without us in the room.
