About this role

Are you a STEM expert fluent in Portuguese (Brazil), eager to shape the future of AI? Large‑scale language models are evolving from clever chatbots into powerful engines of scientific discovery and technical problem-solving. With high‑quality training data, tomorrow’s AI can democratize world‑class education, keep pace with cutting‑edge research, and streamline work for engineers, scientists, and analysts everywhere. That training data begins with you—we need your expertise to help power the next generation of AI.

We’re looking for STEM specialists who live and breathe mathematics, physics, chemistry, engineering, data science, computer science, and scientific computing. You’ll challenge advanced language models on topics like thermodynamics, mechanics, calculus, statistics, materials science, electronics, algorithm design, and quantitative modeling—documenting every failure mode so we can harden model reasoning.

On a typical day, you will converse with the model on real-world STEM problem-solving scenarios and theoretical technical questions, verify factual accuracy and logical soundness, capture reproducible error traces, and suggest improvements to our prompt engineering and evaluation metrics.

A bachelor’s or master’s degree in a STEM discipline is ideal; published research, engineering design experience, data analysis projects, or coding portfolios signal fit. Clear, metacognitive communication—“showing your work”—is essential.

Ready to turn your STEM 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.
