• Professional experience in translation, editing, linguistic annotation, or NLP data work in Spanish.

• Strong understanding of linguistic nuances, regional variations, and context-appropriate usage.

• Interest in AI and LLM-driven language technologies (preferred but not required).

• Excellent attention to detail and ability to spot subtle errors or unnatural phrasing.

• Clear communication skills and experience working in distributed, remote teams.

Why Join

• Contribute to cutting-edge AI research in partnership with a leading research lab.
