About AI Response Evaluation Work

AI training is the human side of building artificial intelligence. Contributors review model outputs, compare answers, write examples, and provide structured judgments that help AI systems become more accurate, clear, useful, and culturally appropriate.

This work is remote and often flexible, making it a strong fit for specialists who want to apply language, editorial, translation, or subject-matter expertise to cutting-edge AI development.

The Role

OpenTrain is seeking an intermediate Japanese AI Response Evaluation Specialist to assess AI-generated content and create high-quality training material. You will evaluate reasoning quality, fact-check information, compare model outputs, and write explanations or model solutions that demonstrate accurate methods.

Japanese localization expertise is central to the role. You will help preserve Japan-specific terminology, tone, cultural nuance, units, names, dates, and references while checking content for accuracy, consistency, and potential bias.

• Remote contractor position
• Part-time engagement requiring 20+ hours per week
• Compensation: $40 USD per hour
• Primary location: Japan
• Languages: Native or near-native Japanese and C1 English

What You’ll Do

You will use editorial judgment, localization knowledge, and structured evaluation methods to review and improve AI-generated content. The work includes both rating existing model responses and generating prompts, responses, explanations, and solutions for AI training.

• Review AI-generated answers for correctness, clarity, and logical reasoning.
• Compare multiple model responses and rate their quality and adherence to the prompt.
• Fact-check information and identify methodological or conceptual errors.
• Write clear explanations and model solutions that demonstrate correct methods.
• Create prompts and responses that support AI training, model improvement, and integrity checks.
• Apply Japanese localization judgment to preserve terminology, tone, and cultural nuance.
• Check localized content for units, names, dates, references, inaccuracies, and bias.
• Use MQM and LQA decision-making, including severity, root-cause, and consistency analysis.

Required Qualifications

This role requires strong Japanese localization judgment, advanced English comprehension, and the ability to make consistent quality decisions across AI-generated content. Candidates should be comfortable interpreting prompts and guidelines in English while evaluating or producing Japanese content.

• Native or near-native Japanese proficiency.

• Japanese translation or localization experience.
• Familiarity with MQM or LQA frameworks, including severity and root-cause analysis.
• Experience with CAT tools, translation memory, termbases, and QA workflows.
• Strong editorial judgment, attention to detail, and fact-checking ability.
• Experience reviewing or generating AI training content and model evaluations.
