Overview

As a Latin American Spanish Linguistic Expert, you’ll assess how well a large language model handles Spanish tasks and help shape the language data used to improve its responses. Your work will cover translation, summaries, dialogue, grammar correction, and other text, with attention to regional usage and cultural context. The project partners with a leading research lab and offers a remote, part-time engagement.

What You'll Do5

  • Review LLM-generated Spanish across translation, summarization, dialogue, grammar correction, and other use cases for quality and accuracy.
  • Edit or rewrite Spanish text to meet Latin American linguistic and cultural standards.
  • Annotate Spanish text for grammatical, syntactic, and semantic features.
  • Spot model errors and gaps in its handling of Spanish, then work with AI researchers to address them.
  • Provide detailed linguistic feedback and analysis to inform ongoing model training.

Requirements6

  • Native or near-native fluency in Latin American Spanish, with strong command of grammar, syntax, and style.
  • Professional experience in Spanish translation, editing, linguistic annotation, or NLP data work.
  • Knowledge of Latin American Spanish regional variation, register, context, and differences from Peninsular Spanish.
  • Professional fluency in English.
  • Strong attention to detail when identifying subtle errors and unnatural phrasing.
  • Clear communication skills and experience working with distributed, remote teams.

Preferred Qualifications1

  • Interest in AI and LLM-based language technology.

Who Should Apply
