• Automate validation for AI‑driven systems, including Agentic AI, LLMs, and data pipelines.
• Test and validate RESTful APIs, data services, and backend microservices for reliability and performance.
• Build and maintain automated regression suites for large‑scale, data‑intensive systems.
• Integrate automated tests within CI/CD pipelines using Azure DevOps, GitHub Actions, or Jenkins.
• Work with data teams to validate data transformations, ETL pipelines, and batch processing jobs.
• Ensure consistent testing coverage across AI services, data APIs, and integration layers.
• Contribute to framework enablement, mentoring peers and improving test automation standards.

Required Qualifications

• Ideally have experience in Python for test automation.
• Proficiency in API testing frameworks such as PyTest, Requests, Robot Framework, or Behave.
• Good understanding of RESTful APIs.
• Experience working with data‑heavy systems and validating ETL pipelines or data transformations.
• Familiarity with CI/CD, Git, and Azure DevOps pipelines.
• Strong understanding of test design, debugging, and failure analysis.
• Hands‑on experience testing or validating AI services (e.g., LLMs, Cognitive Services, or Agentic AI systems).
