Korean Linguistic Specialist for LLM-Powered Chatbot Development F/M

NAVER LABS Europe is part of the R&D division of NAVER, Korea's leading Internet portal and a global tech company with a range of services that include search, commerce, content, fintech, robotics and cloud.

We are seeking a native Korean speaker with a linguistic background to support our Research & Development team in building a large language model (LLM)-powered chatbot. The goal of this chatbot is to provide natural and engaging conversations that allow users to order coffee and various beverages in Korean.

Key Responsibilities

• Language Quality Evaluation
  Assess the fluency, accuracy, and naturalness of Korean text generated by the chatbot's LLM. Identify grammatical issues, unnatural phrasing, and cultural inconsistencies.
• Error Analysis and Model Feedback
  Identify systematic weaknesses or limitations in the model's Korean outputs and document detailed examples illustrating these issues.
• Improvement Strategy Development
  Propose strategies to improve Korean generation quality, including linguistic guidelines, prompt design enhancements, or data augmentation approaches.
• Synthetic Data Creation
  Support the generation and validation of synthetic conversational data in Korean to help train and refine the model's dialogue capabilities.
• Cross-Team Communication
  Serve as a communication bridge between the R&D team and Korean colleagues at NAVER, ensuring a shared understanding of linguistic goals, quality standards, and model updates.

•  

• Type: Fixed-term contract or freelance (depending on candidate's location and availability). Part time.
• Duration: Initial 3–6 months, renewable based on project needs and performance
