Are you a LaTeX 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, enhance academic publishing, and streamline document preparation for researchers 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 LaTeX specialists who live and breathe document typesetting, mathematical formatting, bibliographic management, package customization, template development, and cross-referencing techniques. You’ll challenge advanced language models on topics like complex equation formatting, multi-language document support, Beamer presentations, TikZ graphics, package troubleshooting, and collaborative editing workflows—documenting every failure mode so we can harden model reasoning.

On a typical day, you will converse with the model on document preparation scenarios and theoretical LaTeX questions, verify formatting accuracy and logical consistency, capture reproducible error traces, and suggest improvements to our prompt engineering and evaluation metrics.

A bachelor’s or master’s degree in Computer Science, Mathematics, Physics, or a closely related field is ideal; professional experience in academic publishing, technical writing, or scientific communication signals fit. Clear, metacognitive communication—“showing your work”—is essential. Fluency in Spanish (Spain) is required.

Ready to turn your LaTeX 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.
