Epidemiology Specialist - Freelance AI Trainer Project
About the role
Are you a master of epidemiology 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, accelerate public health insights, and support evidence-based decision-making across the globe. That training data begins with you - we need your expertise to help power the next generation of AI.
We’re looking for epidemiology specialists who live and breathe study design, disease surveillance, outbreak investigation, biostatistics, risk factor analysis, transmission dynamics, public health interventions, and evidence synthesis. You’ll challenge advanced language models on topics like cohort and case-control studies, incidence and prevalence, R₀ and herd immunity, confounding and bias, causal inference, diagnostic test performance, and global health surveillance systems - documenting every failure mode so we can harden model reasoning.
On a typical day, you will converse with the model on real-world epidemiological problems and theoretical scenarios, verify factual accuracy and logical soundness, capture reproducible error traces, and suggest improvements to our prompt engineering and evaluation metrics.
A PhD degree in epidemiology, public health, biostatistics, or a closely related field is ideal; peer‑reviewed publications, applied research in population health, or work in public health agencies or field epidemiology signal fit. Clear, metacognitive communication - “showing your work” - is essential.
Ready to turn your epidemiology 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 $8-to- $65 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.
