About OpenTrain AI

OpenTrain AI is the #1 platform for discovering and building careers in AI training and data labeling. We hire and contract contributors directly, help people build lasting portfolios of AI-training work, and make it easy to grow experience across projects.

This role is offered and managed by OpenTrain AI. Creating an OpenTrain account is free and gives you access to opportunities, project details, and your portfolio of completed work.

Why AI Training Work Matters

AI training (data labeling / human feedback) is the human side of building modern AI systems. Contributors create examples, evaluate outputs, and shape how models behave—work that’s remote, flexible, and accessible to many skill levels.

As a Korean-language quality analyst you’ll be on the front line of personalization: your judgments and written rationales directly influence how conversational AI uses personal information and responds naturally in real-world exchanges.

The Role

You will evaluate personalized Korean AI interactions for a model personalization feature. Work involves creating multi-turn prompts grounded in personal context, rating side-by-side model outputs for helpfulness and naturalness, checking grounding and debug information, and writing concise rationales explaining your decisions.

This is a contract, part-time position requiring 20+ hours per week. Work is remote and open worldwide; compensation is $15.00 USD per hour.

• Employment type: Contractor, Part-time
• Time requirement: 20+ hours/week
• Pay: $15.00 USD per hour
• Language: Korean (reading and writing fluency required)
• Data type: Text; label types: Evaluation rating, RLHF

What You’ll Do Day-to-Day

Your core responsibilities focus on designing and running tests, evaluating outputs, and documenting decisions with clear evidence from each conversation.

• Create and run multi-turn conversational prompts that draw on personal experiences and information.
• Evaluate personalized responses for grounding, natural integration of personal data, and overall helpfulness.
• Compare side-by-side model outputs and select the stronger response based on quality and naturalness.
• Write concise, structured explanations that reference exact parts of the conversation where strengths or issues occur.
• Verify debug information, spot poor inferences or forced connections, and keep evaluation conversations clean by removing them after use.

Requirements

Candidates must meet the essential language and ability criteria below. The role values careful judgment and clear writing more than prior technical credentials.

• Fluent Korean reading and writing ability (required).
• Comfort evaluating grounded, personalized AI responses and designing multi-turn prompts.
• Strong analytical judgment for nuanced AI response review and concise written rationales.
• Attention to detail and the ability to reference exact conversation excerpts when explaining ratings.
• Prior data annotation, AI quality evaluation, or content moderation experience is preferred but not mandatory.
• A BS or BA degree or equivalent experience in an analytical field is preferred.

Who Should Apply

This role is a fit for people who enjoy language, conversation design, and careful quality work. Good candidates are patient, analytical, and able to express why one response is better than another in a few clear sentences.

You do not need advanced machine-learning credentials—strong Korean skills, creative prompt-building, and prior annotation or moderation experience are the primary qualifications.
