We’re looking for Dutch (Suriname/Caribbean) language specialists who live and breathe grammar, orthography, regionalisms, pronunciation patterns, idiomatic expressions, and cultural references unique to these regions. You’ll challenge advanced language models on topics like colloquial usage, contextual interpretation, tone adaptation, syntactic accuracy, and semantic precision—documenting every failure mode so we can harden model reasoning. On a typical day, you will converse with the model in Dutch as used in Suriname and the Caribbean across a wide range of topics, verify linguistic accuracy and cultural relevance, capture reproducible error traces, and suggest improvements to our prompt

We’re looking for a highly skilled Mandarin Chinese voice acting professional who can bring nuance, clarity, and authenticity to training data. You’ll work with cutting-edge AI tools, record and evaluate Mandarin Chinese speech samples, and provide expert feedback on pronunciation, tone, pacing, and emotional expression to strengthen voice models. On a typical day, you will record scripted material, assess AI-generated outputs for linguistic accuracy and naturalness, annotate errors, and collaborate with our team to refine prompts, evaluation methods, and voice design guidelines.
