European Portuguese Linguistic Expert at Mercor

European Portuguese Linguistic Expert | $40/hr | Part-Time | Remote

Mercor is hiring European Portuguese Linguistic Experts for an AI research project run in partnership with a leading research lab. The work focuses on evaluating how effectively a large language model (LLM) performs on European Portuguese tasks and curating high-quality Portuguese linguistic data to train and improve the model's understanding and generation.

What the work involves

• Evaluating the quality and accuracy of LLM-generated Portuguese text across use cases such as translation, summarization, dialogue, and grammar correction.
• Editing, refining, or rewriting Portuguese content to meet linguistic and cultural standards for Portugal.
• Annotating Portuguese text for grammatical, syntactic, and semantic features.
• Identifying model errors and language gaps, and collaborating with AI researchers to improve LLM performance.
• Providing detailed linguistic feedback and analysis to guide ongoing model training efforts.

Who it's for

• Native or near-native fluency in European Portuguese, with excellent command of 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.
• Excellent attention to detail and ability to spot subtle errors or unnatural phrasing.
• Clear communication skills and experience working in distributed, remote teams.
• Interest in AI and LLM-driven language technologies (preferred but not required).
