With high-quality training data, tomorrow's AI can democratize world-class education, keep pace with cutting-edge research, and streamline communication for Spanish speakers everywhere. That training data begins with you—we need your expertise to help power the next generation of AI.

You'll challenge advanced language models on topics like verb conjugation, noun-adjective agreement, subjunctive usage, sentence structure, regional dialects, word order, idiomatic expressions, and cultural nuances - documenting every failure mode so we can harden model reasoning.

A master's or PhD in Spanish language, linguistics, or a closely related field is ideal; peer-reviewed publications, teaching experience, or hands-on linguistic analysis projects signal fit. Clear, metacognitive communication - "showing your work" - is essential.

Ready to turn your Spanish language expertise into the knowledge base for tomorrow's AI? Start teaching the model that will teach the world.
