Multilingual AI jobs
AI training jobs for Portuguese speakers
AI models are far weaker outside English, and closing that gap takes native speakers. Bilingual Portuguese speakers evaluate how models write, reason and stay safe in Portuguese, and catch the mistakes only a native speaker would notice.
Some Portuguese roles are open to generalists; others need a PhD-level background in a STEM field alongside native Portuguese.
