About the role

• Identifying model errors and language gaps, and collaborating with AI researchers to improve LLM performance.

Who this is for

• Native or near-native English fluency, with excellent command of grammar, syntax and stylistics.
• Professional experience in translation, editing, linguistic annotation or NLP data work in English.
• Strong understanding of linguistic nuances, regional variations and context-appropriate usage.
