About The Role

What if your native ear for spoken Brazilian Portuguese could directly shape how AI understands one of the world's most widely spoken languages? We're looking for detail-oriented transcriptionists — including Berlin's internationally connected Brazilian community — to produce accurate, high-quality transcriptions of spoken audio that teach AI systems how real people actually talk.

We're looking for detail-oriented transcriptionists — including Berlin's internationally connected Brazilian community — to produce accurate, high-quality transcriptions of spoken audio that teach AI systems how real people actually talk.

Your ability to capture what's actually being said — with precision and consistency — is what makes this role essential.

This is a fully remote, flexible contract role. No prior AI experience needed — just native-level Brazilian Portuguese, strong listening skills, and a commitment to following detailed guidelines.
