Korean Linguistic Expert at Mercor

Korean Linguistic Expert | $40/hr | Remote | Part-Time

Mercor is hiring Korean Linguistic Experts for a remote, part-time AI research project run in partnership with a leading research lab. The work centers on evaluating how well a large language model (LLM) performs on Korean-language tasks and on curating high-quality Korean linguistic data to train and improve the model's understanding and generation capabilities.

What the work involves

• Evaluating the quality and accuracy of LLM-generated Korean text across use cases such as translation, summarization, dialogue, and grammar correction.
• Editing, refining, or rewriting Korean content to meet linguistic and cultural standards for Korean-speaking audiences.
• Annotating Korean 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.

Who this is for

• Native or near-native fluency in Korean, with excellent command of grammar, syntax, and stylistics.
• Professional experience in translation, editing, linguistic annotation, or Korean NLP data work.
• Strong understanding of Korean nuances, regional variations, register, and context-appropriate usage.
• Professional fluency in English.
• Excellent attention to detail, including spotting subtle errors or unnatural phrasing.
• Clear communication skills and experience working in distributed, remote teams.
• Interest in AI and LLM-driven language technologies is preferred but not required.
