Summary

About this role

In this hourly-paid, fully remote contractor role, you will review AI-generated responses and/or generate language content, evaluate reasoning quality and step-by-step problem-solving, and provide expert feedback so outputs are accurate, logical, and clearly explained. You will assess solutions for accuracy, clarity, and adherence to the prompt; identify errors in methodology or conceptual understanding; fact-check information; write high-quality explanations and model solutions that demonstrate correct methods; and rate and compare multiple AI responses based on correctness and reasoning quality. You will apply senior-level Japanese localization/translation judgment alongside Minimum C1 English proficiency to ensure terminology, tone, and cultural nuance are consistently correct across use cases. This role is with SME Careers, a fast-growing AI Data Services company and a subsidiary of SuperAnnotate that provides AI training data for many of the world's largest AI companies and foundation-model labs. Your work directly helps improve the world's premier AI models.

Important:
There is no immediate project for this role; however, if qualified, you will be among the first experts we reach out to when relevant opportunities arise. This will also provide you with access to future projects available through our expert network.

Your profile
  • Bachelor's degree or higher in Japanese Translation, Linguistics, Localization, Communications, or a related field.
  • Native or near-native Japanese proficiency and strong command of the locale conventions for Japan.
  • Minimum C1 English proficiency (reading/writing) for interpreting prompts, sources, and evaluation guidelines.
  • 5+ years of professional localization/translation experience (multilingual localization experience strongly preferred).
  • Demonstrated ability to apply MQM/LQA concepts (severity, category, and root-cause thinking) to produce consistent quality decisions.
  • Proficiency with CAT tools and QA workflows (translation memory, termbases, automated checks) and comfort working with structured guidelines.
  • Excellent editorial judgment (register, tone, inclusivity, and cultural nuance) with extreme attention to detail.
  • Ability to rigorously fact-check localized content (units, references, names, dates) using reliable sources and consistent reasoning.
  • Comfort working as an hourly contractor: dependable throughput, clear documentation, and responsiveness across time zones.
  • Previous experience with AI data training / annotation / evaluation is preferred.
Key responsibilities
  • Develop AI Training Content: Create detailed prompts in various topics and responses to guide AI learning, ensuring the models reflect a comprehensive understanding of diverse subjects.
  • Optimize AI Performance: Evaluate and rank AI responses to enhance the model's accuracy, fluency, and contextual relevance.
  • Ensure Model Integrity: Test AI models for potential inaccuracies or biases, validating their reliability across use cases.
