Japanese Linguistic Expert | $40/hr | Part Time | Remote

Mercor is hiring Japanese linguistic experts for an AI research project run in partnership with a leading research lab. You will evaluate how well a large language model (LLM) handles Japanese-language tasks and curate high-quality Japanese linguistic data to improve the model's understanding and generation.

What you'll do

• Evaluate the quality and accuracy of LLM-generated Japanese text across use cases such as translation, summarization, dialogue, and grammar correction.
• 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.
• 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.

Who this is for

• Native or near-native fluency in Japanese, with a strong command of grammar, syntax, and stylistics.
• Professional experience in translation, editing, linguistic annotation, or NLP data work in Japanese.
• Understanding of Japanese nuances, regional variations, register, and context-appropriate usage.
• Professional fluency in English.
• Interest in AI and LLM-driven language technologies (preferred, not required).
• Attention to detail, including the ability to spot subtle errors or unnatural phrasing.
• Clear communication skills and experience working in distributed, remote teams.
