Mercor is seeking experienced Spanish Linguistic Experts to join a cutting-edge AI research project in partnership with a leading research lab. This role centers on evaluating how effectively a large language model (LLM) performs in Spanish-language tasks and on curating high-quality Spanish linguistic data to train and improve the model's understanding and generation capabilities.

Key Responsibilities

  • Evaluate the quality and accuracy of LLM-generated Spanish text across various use cases (e.g., translation, summarization, dialogue, grammar correction).
  • Edit, refine, or rewrite Spanish content to meet linguistic and cultural standards.
  • Annotate Spanish text for grammatical, syntactic, and semantic features.
  • Identify model errors and language gaps, and collaborate with AI researchers to improve LLM performance.
  • Provide detailed linguistic feedback and analysis to guide ongoing model training efforts.

You're a strong fit if you have

  • Native or near-native fluency in Spanish, with excellent command over grammar, syntax, and stylistics.
  • Professional experience in translation, editing, linguistic annotation, or NLP data work in Spanish.
  • Strong understanding of linguistic nuances, regional variations, and context-appropriate usage.
  • Interest in AI and LLM-driven language technologies (preferred but not required).
  • Excellent attention to detail and ability to spot subtle errors or unnatural phrasing.
  • Clear communication skills and experience working in distributed, remote teams.

Why Join

  • Contribute to cutting-edge AI research in partnership with a leading research lab.
  • Work on high-impact projects that directly support the development of advanced AI systems.
  • Gain hands-on exposure to state-of-the-art AI research and development.
  • Join a fast-moving project where your expertise and judgment can have a meaningful impact.
