Overview

As a Spanish (United States) Linguistic Expert, you will assess how a large language model handles U.S. Spanish across translation, summarization, dialogue, and grammar correction. You will also refine and annotate language data, then share findings with AI researchers to support model training and improve Spanish text generation and understanding. The project partners with a leading research lab and offers remote, part-time work focused on U.S. Spanish usage and cultural context.

What You'll Do5

  • Assess the quality and accuracy of LLM-generated Spanish for translation, summarization, dialogue, and grammar correction.
  • Edit, refine, or rewrite Spanish content to meet linguistic and cultural standards for Spanish-speaking communities in the United States.
  • Annotate Spanish text for grammatical, syntactic, and semantic features.
  • Find model errors and language gaps, and work with AI researchers to improve model performance.
  • Provide detailed linguistic feedback and analysis to inform ongoing model training.

Requirements6

  • Native or near-native fluency in Spanish as used in the United States, with excellent command of grammar, syntax, and style.
  • Professional experience in Spanish translation, editing, linguistic annotation, or NLP data work.
  • Strong knowledge of U.S. Spanish nuances, regional variation, register, and context-appropriate usage, including differences from Latin American and Peninsular Spanish.
  • 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

Candidates with native or near-native U.S. Spanish, professional language or NLP data experience, and strong English skills will fit the work. A close ear for regional usage and subtle language issues will help them assess model output and give researchers useful feedback.

Salary Insight

The rate is $40 per hour. The work calls for experienced Spanish-language expertise in evaluation, editing, or annotation, with compensation tied to hourly project work.
