Required Qualifications Bachelor’s degree in CS, CE, EE, or a related field. Proficiency in programming languages such as Python. Strong experience in software testing (especially AI-related software) methodologies, including test case design, automation, and defect tracking. Deep experience with backend testing, including API testing (e.g., REST/gRPC) and performance testing. Experience with containerization and deployment tools like Docker and Kubernetes. Strong problem-solving skills and effective communication abilities. Preferred Qualifications Experience developing LLM-related and AI agent-related products.
