We’re looking for a highly skilled Cantonese language specialist who can bring linguistic depth, cultural context, and precision to training data. You’ll work with cutting‑edge AI tools, evaluate and refine Cantonese text outputs, and provide expert feedback on grammar, syntax, semantics, style, and cultural appropriateness to strengthen model performance.

On a typical day, you will review and annotate Cantonese content, assess AI-generated outputs for accuracy and fluency, identify and document error patterns, and collaborate with our team to refine prompts, evaluation methods, and linguistic guidelines.

Fluency in Cantonese is required, along with demonstrated experience in translation, linguistics, language teaching, editing, or related professional work. Experience in training, coaching, or linguistic annotation is a plus. Clear communication skills, cultural knowledge, and attention to detail are essential.
