Multilingual AI Evaluator - Portuguese & Spanish

AI models are predominantly trained on English-language data. Native Portuguese and Spanish speakers with strong academic language skills are among the most valuable contributors to closing the multilingual quality gap in frontier AI systems - and demand from the world's top LLM companies for exactly this expertise is growing rapidly.

Language Fellows contribute directly to multilingual evaluation projects commissioned by the world's leading AI labs. The companies building the most advanced models in the world need native European language speakers with academic credentials - and Sovrano AI is one of the only platforms in Europe that can supply them at verified scale. Your native language is a professional asset here.

Native fluency is necessary but not sufficient. We require evaluators who can articulate precisely why a model's output is wrong - not just that it feels off. Linguistic intuition must be backed by structured written reasoning.
