Real-world linguistics experience such as teaching, peer‑reviewed publications, or hands-on linguistic analysis projects
Experience evaluating or prompting language models, documenting error traces, and communicating reasoning clearly (metacognitive communication)
Ability to articulate and document model failures and propose improvements to prompt engineering and evaluation metrics

Requirements:

Interact with large language models in Japanese on topics like verb conjugation, sentence structure, honorifics, formal and informal speech, regional dialects, kanji readings, and writing nuances; document failure modes to harden model reasoning
Verify factual accuracy and logical soundness of model outputs; capture reproducible error traces
Provide actionable feedback to improve prompts, evaluation metrics, and training data quality for future model iterations

Job description

Are you a Japanese language expert eager to shape the future of AI? Large‑scale language models are evolving from clever chatbots into powerful engines of linguistic discovery. With high‑quality training data, tomorrow’s AI can democratize world‑class education, keep pace with cutting‑edge research, and streamline communication for Japanese speakers everywhere. That training data begins with you—we need your expertise to help power the next generation of AI.

We’re looking for Japanese language specialists who live and breathe Japanese grammar, syntax, morphology, kanji, hiragana, katakana, phonology, and pragmatics. You’ll challenge advanced language models on topics like verb conjugation, sentence structure, honorifics, formal and informal speech, regional dialects, kanji readings, and the nuances of Japanese writing systems—documenting every failure mode so we can harden model reasoning.

On a typical day, you will converse with the model on language scenarios, verify factual accuracy and logical soundness, capture reproducible error traces, and suggest improvements to our prompt engineering and evaluation metrics.

A degree is not required for this role; real-world experience speaks louder. Peer‑reviewed publications, teaching experience, or hands‑on linguistic analysis projects signal fit. Clear, metacognitive communication—“showing your work”—is essential.

Ready to turn your Japanese language expertise into the knowledge base for tomorrow’s AI? Apply today and start teaching the model that will teach the world.

We offer a pay range of $8-to- $65 per hour, with the exact rate determined after evaluating your experience, expertise, and geographic location. Final offer amounts may vary from the pay range listed above. As a contractor you’ll supply a secure computer and high‑speed internet; company‑sponsored benefits such as health insurance and PTO do not apply.
