About the Role

The role We are hiring native and near-native Brazilian Portuguese speakers to audit AI training data in their own language, not to produce it. You will work across two Amazon Sonic audit collections:

What You'll Do

  • You listen, judge, and submit. Where you find an error you tag every applicable error code, not just the first one, and you explain in plain language why the task passed or failed. Critical errors are called out first so the reason for a failure is obvious to the reader.
  • You will complete a short calibration phase before production work begins.

You're a Good Fit If You

  • Native or near-native command of Portuguese as spoken in Brazil. You were either born and raised in a region where this language and variety is dominant, or you are fully fluent with five or more years of residence in such a region. This is a hard requirement.
  • Strong English reading and writing. All conventions, error codes, and audit rationale are written in English, so you need to read a detailed rulebook and write clear feedback in it.
  • Disciplined rubric application. The work rewards people who apply a written standard consistently across hundreds of judgments rather than relying on instinct. Prior transcription, subtitling, localization, linguistic annotation, or QA experience is a strong signal.
  • Careful listening. You can distinguish similar sounds, identify where one word ends and the next begins in continuous speech, and tell genuine acoustic ambiguity apart from a clear annotator error.
  • Helpful but not required: prior AI data annotation or model evaluation work, a phonetics or linguistics background, and experience with audio editing or waveform tools.
