Experience with AI/ML-driven systems would be an advantage, but curiosity and a desire to learn in this space are just as valuable.

• Strong knowledge of Python and/or C# for backend and API testing
• Experience with Cypress or Playwright for frontend automation
• Hands‑on experience building and managing test pipelines in CI/CD

• Solid understanding of the test pyramid and applying test approaches across unit, integration, and UI layers
• Exposure to Azure environments and cloud‑native systems is desirable
• Interest or experience in AI/ML products is a plus
