Experience testing machine learning frameworks or other complex, non-deterministic systems.

Deep knowledge of developer tools, SDKs, or framework testing and validation methodologies.

Familiarity with continuous integration (CI) systems and advanced build automation.

Experience using Python for test automation, custom tooling, or machine learning pipelines.
