Meridial Marketplace (by Invisible) is hiring Korean Language Specialists as freelance AI trainers to shape large language models. Contributors converse with advanced language models on Korean linguistic scenarios, verify accuracy, capture error patterns, and suggest improvements across grammar, syntax, morphology, phonetics, semantics, pragmatics, honorifics, sentence structure, verb conjugation, word order, regional dialects, idiomatic expressions and script variations. Requires deep expertise in the Korean language; a degree is not required but peer-reviewed publications, teaching experience or hands-on linguistic analysis demonstrate fit. This is a remote, worldwide contract role paying $6–$65/hour depending on experience and geographic location; contractors supply their own computer and internet, with no company benefits.
