Overview

General Translation seeks a Spanish Linguistic Expert for a remote, part-time AI research project with a leading research lab. You will assess Spanish output from a large language model across tasks such as translation, summaries, dialogue, and grammar correction, then help shape Spanish-language data for model training. Your language expertise will also help researchers identify gaps and improve the model’s Spanish comprehension and generation.

What You'll Do5

  • Review LLM-generated Spanish for accuracy and quality across translation, summarization, dialogue, and grammar correction.
  • Edit, improve, or rewrite Spanish material to suit the linguistic and cultural expectations of Spanish-speaking audiences.
  • Annotate Spanish text for grammatical, syntactic, and semantic features.
  • Flag model errors and language gaps, and work with AI researchers on improvements to Spanish performance.
  • Write detailed linguistic feedback and analysis to inform ongoing model training.

Requirements6

  • Native or near-native Spanish fluency and excellent command of grammar, syntax, and style.
  • Professional experience in Spanish translation, editing, linguistic annotation, or NLP data work.
  • Strong knowledge of Spanish regional variation, nuance, register, and context-appropriate usage.
  • Professional fluency in English.
  • Close attention to detail, including the ability to catch subtle errors and unnatural phrasing.
  • Clear communication skills and experience working with distributed, remote teams.

Preferred Qualifications1

  • Interest in AI and LLM-based language technologies.

Who Should Apply
