Korean/English Bilingual AI Trainer & Evaluator (Remote, Hourly Contractor)

Position Summary

This is a fully remote, hourly contractor role supporting AI data and language projects on a project-based, flexible hour basis. Project scopes vary and may include:

• Data annotation: labeling, classifying, and structuring documents, tables, and other content to support AI training datasets.

• LLM evaluation: reviewing AI-generated responses for accuracy, reasoning quality, coherence, and cultural/linguistic appropriateness.

• Content generation: writing high-quality prompts and model responses, or recording high-quality voice samples, to guide AI learning across diverse topics.

• Localization QA: ensuring terminology, tone, cultural nuance, and locale-specific details (units, references, names, dates) are consistently accurate across outputs.
  
  

You will apply senior-level Korean localization and translation judgment alongside minimum C1 English proficiency to ensure terminology, tone, and cultural nuance are consistently accurate across use cases.

Profile Requirements

• Bachelor's degree or higher in Translation, Linguistics, Localization, Communications, or a related field.

• Native Korean proficiency with strong writing and editing skills.

• Minimum C1 English proficiency (reading/writing) for interpreting prompts, source materials, and evaluation guidelines.

• Excellent editorial judgment in register, tone, punctuation, inclusivity, and cultural nuance, with extreme attention to detail.

• Ability to identify meaning drift, ambiguity, locale inconsistencies, and subtle errors, and to explain corrections clearly in writing.

• Ability to rigorously fact-check localized content (units, references, names, dates) using reliable sources and consistent reasoning.

• Ability to identify reasoning gaps, methodological errors, and unclear explanations even when language is fluent.

• Reliable, self-directed, and able to deliver consistent quality with clear communication and responsiveness across time zones.
  
  

Preferred Experience

• Professional localization or translation experience.

• Familiarity with MQM/LQA concepts (severity, category, and root-cause thinking) for consistent quality decisions.

• Proficiency with CAT tools and QA workflows (translation memory, termbases, automated checks).

• Previous experience with AI data training, annotation, or evaluation.
