. Are you a bilingual professional fluent in Korean and Japanese eager to shape the future of AI?

Large-scale language models are transforming the way we learn, work, and communicate—enabling cross-cultural understanding and more natural multilingual interactions. With high-quality training data, tomorrow’s AI can deliver more accurate, reliable, and culturally aware communication across languages and contexts. That training data begins with you—your expertise will help power the next generation of AI.

We’re looking for a Korean–Japanese Bilingual Specialist who can bring linguistic precision, cultural knowledge, and critical thinking to training data. You’ll work with cutting-edge AI tools, evaluate translations and conversations between Korean and Japanese, and provide structured feedback to improve accuracy, fluency, and cultural alignment.

On a typical day you will review AI-generated translations, annotate errors, assess responses for naturalness and context, and collaborate with our team to refine prompts, evaluation methods, and linguistic guidelines. Tasks may include verifying terminology, testing conversational flow, and ensuring accurate rendering of idiomatic expressions and domain-specific language.

Fluency in both Korean and Japanese is required, with strong reading, writing, and communication skills in each. Experience in translation, interpretation, localization, or linguistics is a strong plus. Attention to detail and the ability to explain linguistic or cultural nuances clearly are essential.

Ready to channel your bilingual expertise into building the AI tools of tomorrow? Apply today and help train the model that will support multilingual communication for millions worldwide.

Pay range: $8 to $65 per hour, with the exact rate determined after evaluating your experience, expertise, and geographic location. As a contractor, you’ll supply a secure computer and reliable internet connection; company-sponsored benefits such as health insurance and PTO do not apply.
