Data Annotation Specialist, Simplified Chinese / Mandarin

Who are we?

Our mission is to scale intelligence to serve humanity. We’re training and deploying frontier models for developers and enterprises who are building AI systems to power magical experiences like content generation, semantic search, RAG, and agents. We believe that our work is instrumental to the widespread adoption of AI.

Why this role?

We are on a mission to build machines that understand the world and make them safely accessible to all. Data quality is foundational to this process. Machines (or Large Language Models to be exact) learn in similar ways to humans – by way of feedback. By labelling, ranking, auditing, and correcting text output, you will improve large‑language‑model performance for future iterations, thus having a lasting impact on Cohere’s tech.

Cohere seeks dynamic and dedicated Data Annotators with exceptional Chinese writing, translation, and data manipulation skill.
