About the role

Pay: $40 per hour (USD).

Mercor is seeking experienced European Portuguese 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 European Portuguese-language tasks and on curating high-quality Portuguese linguistic data to train and improve the model's understanding and generation capabilities.

Key Responsibilities:

  • Evaluate the quality and accuracy of LLM-generated Portuguese text across various use cases (e.g., translation, summarization, dialogue, grammar correction).

  • Edit, refine, or rewrite Portuguese content to meet linguistic and cultural standards for Portugal.

  • Annotate Portuguese 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 European Portuguese, with excellent command over grammar, syntax, and stylistics.

  • Professional experience in translation, editing, linguistic annotation, or NLP data work in Portuguese.

  • Strong understanding of European Portuguese nuances, regional variations, register, and context-appropriate usage, including how it differs from Brazilian Portuguese.

  • Professional fluency in English.

  • 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.
