AI Data Specialist - Spanish

About the role

This role owns the complete lifecycle for AI text in Spanish. You will design intake rules, construct datasets, audit quality, and release validated outputs to partners. The contract requires 3-5 fluent residents of Mexico City who will guard tone and meaning while moving files through defined stages. You will translate strategic goals into concrete data tasks that keep the Spanish experience consistent and reliable. Every decision you make will influence how AI systems understand and respond to Mexican users in everyday contexts. You will work independently, managing your schedule while maintaining clear communication with remote engineering partners. This position is ideal for detail-oriented individuals who take pride in delivering high-quality data work on time.
