Job description

Mathematics Specialist (Fluent in Spanish - Spain) – AI Trainer

Join to apply for the Mathematics Specialist (Fluent in Spanish - Spain) – AI Trainer role at Invisible Expert Marketplace.

Are you a mathematics expert fluent in Spanish (Spain), 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 academic work for students and professionals everywhere. That training data begins with you—we need your expertise to help power the next generation of AI.

We’re looking for mathematics specialists who love algebra, calculus, number theory, linear algebra, differential equations, statistics, geometry, mathematical logic, and discrete mathematics. You’ll challenge advanced language models on topics like real and complex analysis, optimization theory, mathematical proofs, set theory, probability distributions, cryptographic algorithms, and applied mathematics—documenting every failure mode so we can improve model reasoning.

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

A master’s or PhD in mathematics or a related field is ideal; peer-reviewed publications, teaching experience, research, or hands-on experience with mathematical modeling are a plus. Clear, detailed communication—"showing your work"—is essential.

Ready to turn your mathematics expertise into the foundation for tomorrow’s AI? Apply today and help teach the model that will teach the world.

We offer a pay range of $6 to $65 per hour, with the final rate based on your experience, expertise, and location. As a contractor, you’ll provide a secure computer and high-speed internet; benefits such as health insurance and PTO are not included.
