Overview

As a Japanese Linguistic Expert, you will assess how well a large language model handles Japanese tasks and prepare language data that helps improve its understanding and text generation. The work covers translation, summarization, dialogue, and grammar correction, along with linguistic annotation and detailed feedback for AI researchers. The project runs remotely on a part-time basis and supports research with a leading lab.

What You'll Do5

  • Review LLM-generated Japanese across translation, summarization, dialogue, grammar correction, and other use cases for quality and accuracy.
  • Edit, refine, or rewrite Japanese content to meet linguistic and cultural standards for Japanese-speaking audiences.
  • Annotate Japanese text for grammatical, syntactic, and semantic features.
  • Spot model errors and gaps in Japanese language performance, then work with AI researchers to address them.
  • Provide detailed linguistic analysis and feedback to inform ongoing model training.

Requirements6

  • Native or near-native Japanese fluency, with strong command of grammar, syntax, and stylistics.
  • Professional experience in Japanese translation, editing, linguistic annotation, or NLP data work.
  • Strong understanding of Japanese nuance, regional variation, register, and context-appropriate usage.
  • Professional fluency in English.
  • Careful attention to detail when identifying subtle errors or unnatural phrasing.
  • Clear communication skills and experience working with distributed, remote teams.

Preferred Qualifications1

  • Interest in AI and LLM-based language technologies.

Who Should Apply

Japanese language specialists with professional experience in translation, editing, annotation, or NLP data work will find a close fit here. The role suits candidates who can judge nuance across registers and regional variations and communicate findings in professional English.
