Safety Policy Language Specialist with Japanese language
We are seeking a Safety Policy Language Specialist (Japanese) to work at the intersection of generative AI, Trust & Safety, and sociocultural linguistics. In this role, you will be responsible for developing, adapting, and applying safety policies and annotation guidelines through a regional and linguistic lens.
You will ensure generative AI safety policies reflect the linguistic realities, societal norms, and sensitive topics unique to the Japanese market. Serving as the critical bridge between global safety principles and localized execution, you will identify emerging risk patterns, build culturally authentic ground-truth datasets, evaluate LLM outputs, and diagnose model safety failures on complex, nuanced Japanese language.
Essential functions
- Guideline & Policy Development: Partner with other teams to draft, adapt, and refine market-specific safety guidelines, and policy definitions for the target locale.
- Linguistic & Cultural Contextualization: Translate abstract safety policies into actionable local standards, providing clear definitions and localized examples of edge cases, regional slang, euphemisms, and indirect harmful intent.
- Exemplar Dataset Creation: Develop and validate high-quality, culturally authentic ground-truth (exemplar) datasets to calibrate autograders and guide third-party annotation teams.
- Prompt & Evaluation Adaptation: Adapt English safety prompts and test sets into culturally natural, dialectally accurate language rather than literal translations.
- Model Failure Analysis: Investigate safety-related model failures, diagnosing whether errors stem from regional dialectal quirks, coded language, or cultural misunderstandings, and update guidelines accordingly.
- Regional Safety Advisory: Act as the subject matter expert on local sensitive topics, emerging internet culture, social context, and regulatory or cultural taboos for the target region.
Qualifications
Native-level fluency with deep, current cultural immersion and living experience in the target market (Japanese - Japan).
Demonstrated experience developing, adapting, or refining content policies and safety guidelines in the target language/market.
Experience applying or working with harm and risk taxonomies, classification frameworks, or core safety policy principles.
Proven ability to analyze nuanced language: identifying market-specific slang, regional idioms, double entendres, veiled speech, and cultural sensitivities.
Professional background in Linguistics, Translation/Localization, Trust & Safety, Content Moderation, or AI Policy Evaluation.
Experience evaluating sensitive, policy-violating, or Responsible AI content.
Experience working with LLM evaluation, prompt assessment, or data labeling workflows.
