We’re looking for German speakers who understand the nuances of grammar, usage, spelling, tone, and cultural context in both formal and informal German. You’ll challenge advanced AI models with linguistic edge cases, cultural subtleties, translation ambiguities, and phrasing differences—documenting model failures and guiding improvements with clarity and precision. On a typical day, you will engage in text-based conversations with the model, evaluate its responses for accuracy and fluency, annotate linguistic patterns, test comprehension across a range of German language inputs, and suggest refinements to prompts and evaluation methods.

We’re looking for Korean language specialists who live and breathe Korean grammar, syntax, morphology, phonetics, semantics, and pragmatics. You’ll challenge advanced language models on topics like honorifics, sentence structure, verb conjugation, word order, regional dialects, idiomatic expressions, and script variations—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.
