• *Why This Role Exists**

Mercor partners with leading AI teams to improve the quality, usefulness, and reliability of general-purpose conversational AI systems. These systems are used across a wide range of everyday and professional scenarios, and their effectiveness depends on how clearly, accurately, and helpfully they respond to real user questions. In healthcare-related scenarios, accuracy and clarity are essential. This project focuses on evaluating and improving how conversational AI systems respond to medical and healthcare topics. Your expertise helps ensure responses are factually correct, clearly explained, and aligned with real-world healthcare knowledge and communication standards.
