Physician Assistant jobs in London

Are you a medical doctor eager to shape the future of AI? Large-scale language models are evolving from clever chatbots into powerful engines of scientific discovery. With high-quality training data, tomorrow's AI can democratize world-class education, keep pace with cutting-edge research, and streamline clinical work for healthcare professionals everywhere. That training data begins with you—we need your expertise to help power the next generation of AI.

We're looking for medical professionals who live and breathe internal medicine, pharmacology, pathology, clinical diagnostics, medical ethics, human physiology, epidemiology, immunology, and evidence-based medicine. You'll challenge advanced language models on topics like differential diagnosis, drug interactions, treatment protocols, pathophysiological mechanisms, clinical trial design, public health interventions, and diagnostic imaging interpretation—documenting every failure mode so we can harden model reasoning.

On a typical day, you will converse with the model on clinical scenarios and theoretical medical questions, verify factual accuracy and logical soundness, capture reproducible error traces, and suggest improvements to our prompt engineering and evaluation metrics.

An MD or DO is required for this role. Clear, metacognitive communication—explicitly articulating reasoning and decision processes "showing your work"— is essential.

Ready to turn your medical expertise into the knowledge base for tomorrow's AI? Apply today and start teaching the model that will teach the world.

We offer a pay range of $40 - $120 per hour, with the exact rate determined after evaluating your experience, expertise, and geographic location. Final offer amounts may vary from the pay range listed above. As a contractor you'll supply a secure computer and high-speed internet; company-sponsored benefits such as health insurance and PTO do not apply.
