What You'll Do

• Design Complex Clinical Scenarios: Create detailed case studies and clinical reasoning tasks across specialties to test how systems interpret symptoms, assess risks, and prioritize care.
• Evaluate Decision-Making Approaches: Review and critique structured outputs for clinical safety, accuracy, and sound judgment. Identify errors in logic or inappropriate treatment suggestions.
• Shape Reasoning Frameworks: Provide structured, example-driven feedback to improve how models understand differentials, guidelines, and clinical narratives.
• Work Across Specialized Projects: Contribute to targeted workstreams in internal medicine, emergency care, radiology, psychiatry, and other domains aligned with your background.

Who Should Apply

• Nurse practitioners, physician assistants, and registered nurses with deep clinical experience may also be considered.
• Fluency in written English is required.

• Pathways for Growth: High-impact contributors may be invited to join additional review projects, advisory roles, or research collaborations.
