We're hiring proficient bilingual speakers (English & Japanese) to help make advanced AI models safer. You'll apply your language fluency and cultural judgment to evaluate and strengthen how these models handle sensitive topics in Japanese.

• Apply structured guidelines to classify prompts and conversations.

• Flag adversarial phrasings and escalation patterns, and document the reasoning behind your judgments.

What we're looking for

• Native or near-native fluency in Japanese, plus business-level written English.

• A bachelor's degree, completed or in progress.

• Strong written reasoning and a high level of attention to detail.

• Sound judgment around sensitive and dual-use information.

Nice to have

• Based in Japan or the wider East Asia region. This is a preference, not a requirement, applicants based elsewhere are welcome.

• Experience reviewing, grading, or red-teaming written or technical content.

• Background in trust and safety, content moderation, policy evaluation, or adversarial testing.
