Portuguese Language Expert (Brazil) — Annotation & Review (micro1)
What the work involves
The Brazilian Portuguese role at micro1 is an annotation job first and a language job second, which makes it different from the audio-review work in the same family. You label and curate Portuguese language data for AI and machine learning, check it for linguistic accuracy and consistency, and keep the standard steady across a batch that other people will build on. Regional variation is where the value sits. Brazilian Portuguese shifts in vocabulary and register between states, and an annotation that flattens those differences into one neutral norm is less useful than one that records them. You also review translations and language usage, document the process, and suggest where the workflow could be tightened.
Pay is $30–$65/hr, 15 openings, part-time, contractor, fully remote, with native or near-native Portuguese and working English. No prior AI experience is required — annotation discipline is the qualification.
