Overview

As a Brazilian Portuguese Linguistic Expert, you’ll assess how well a large language model handles Portuguese tasks and prepare linguistic data that can improve its language understanding and generation. The work spans text evaluation, editing, annotation, and feedback for AI researchers on a project with a leading research lab. This remote, part-time role calls for strong command of Brazilian Portuguese and professional English fluency.

What You'll Do5

  • Review LLM-generated Portuguese text for quality and accuracy across translation, summarization, dialogue, and grammar correction.
  • Edit, refine, or rewrite Portuguese content to meet Brazilian linguistic and cultural standards.
  • Annotate Portuguese text for grammatical, syntactic, and semantic features.
  • Flag model errors and language gaps, then work with AI researchers on improving model performance.
  • Provide detailed linguistic analysis and feedback to inform ongoing model training.

Requirements6

  • Native or near-native fluency in Brazilian Portuguese, with excellent command of grammar, syntax, and style.
  • Professional experience in Portuguese translation, editing, linguistic annotation, or NLP data work.
  • Strong knowledge of Brazilian Portuguese nuances, regional variation, register, and context-appropriate usage, including differences from European Portuguese.
  • Professional fluency in English.
  • Careful attention to detail, including the ability to spot subtle errors and unnatural phrasing.
  • Clear communication skills and experience working with distributed, remote teams.

Preferred Qualifications1

  • Interest in AI and LLM-based language technology.

Who Should Apply

Candidates with professional Portuguese language experience and native or near-native Brazilian Portuguese fluency will be well suited to this work. Familiarity with Brazilian regional usage, strong English, and an interest in language models can help them contribute useful evaluations and training feedback.
