Overview

A leading research lab needs a part-time Spanish (Spain) specialist to judge how well a large language model handles Peninsular Spanish. You will review model output in tasks such as translation, summarization, dialogue, and grammar correction, then annotate and edit Spanish text to meet Spain-specific standards. The project pairs close linguistic analysis with LLM evaluation and NLP data work, and your feedback goes to AI researchers who tune model behavior. The role runs remotely and calls for professional fluency in both Spanish (Spain) and English.

What You'll Do5

  • Review Spanish text produced by a large language model across translation, summarization, dialogue, and grammar correction use cases.
  • Edit or rewrite Spanish content so it meets linguistic and cultural standards for Spain.
  • Annotate Spanish passages for grammar, syntax, and meaning.
  • Flag model errors and language gaps, then share findings with AI researchers to shape improvements.
  • Give detailed linguistic feedback and analysis that guides model training.

Requirements6

  • Native or near-native command of Spanish (Spain), including grammar, syntax, and style.
  • Professional background in Spanish translation, editing, linguistic annotation, or NLP data work.
  • Deep familiarity with Peninsular Spanish register, regional variation, and context-specific usage, plus how it differs from Latin American Spanish.
  • Professional fluency in English.
  • Sharp eye for subtle errors and unnatural phrasing.
  • Clear communication and experience in distributed remote teams.

Preferred Qualifications1

  • Interest in AI and LLM-driven language technologies
