Job description

Are you a Spanish (Mexico) language expert eager to shape the future of AI? Large-scale language models are evolving from clever chatbots into powerful tools for communication, education, and cultural preservation. With high-quality training data, tomorrow's AI can better understand regional language nuances, context, and tone - empowering global accessibility and fostering cross-cultural exchange. That training data begins with you - we need your expertise to help power the next generation of AI.

We're looking for Spanish (Mexico) language specialists who live and breathe grammar, orthography, vocabulary, idiomatic expressions, and cultural references unique to Mexico. You'll challenge advanced language models on topics like regional colloquialisms, contextual interpretation, tone adaptation, syntactic accuracy, and semantic precision - documenting every failure mode so we can harden model reasoning.

On a typical day, you will converse with the model in Spanish (Mexico) across a wide range of topics, verify linguistic accuracy and cultural relevance, capture reproducible error traces, and suggest improvements to our prompt engineering and evaluation metrics.

A Master's degree in Linguistics, Translation, Spanish Language, Literature, or a related field is ideal; professional experience in teaching, translation, localization, or editorial work signals fit. Clear, metacognitive communication - "showing your work" - is essential.

Ready to turn your Spanish (Mexico) expertise into the knowledge base for tomorrow's AI?

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.
