Job description

Overview

Japanese exposes AI quickly: it mishandles keigo, mixing polite, humble, and honorific speech in ways that would embarrass a real speaker, and it fumbles counters and particles. It can build grammatical sentences that still land at the wrong level of politeness, and a native reader is who feels the mismatch.

As a Japanese Expert, you'll judge and correct AI output in Japanese, teaching models to match the register a real reader expects.

What you’ll actually do

• Review translations between English and Japanese for meaning, flow, and the right level of keigo.
• Score and rank model output in Japanese, catching misused honorifics, wrong counters, and stiff particles.
• Write the better version when the model misses, natural enough to read as native.

Roles this fits

Common backgrounds: Japanese Linguist, Bilingual Reviewer, Localization Specialist.

What we look for

• Native or near-native fluency in Japanese.
• Command of keigo and the registers of everyday speech.
• Clear written English: your explanations are the training signal.
• No degree required. We care about what you can do, not where you learned it.

Compensation

Up to $40/hr depending on task difficulty and specialization. Many contributors add $100k–$200k a year; some make it their full-time income.
