About this role
Mercor is seeking experienced 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 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.
- 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 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 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.
