This opportunity is embedded within a high-profile project aimed at improving how AI systems process spoken language for Portuguese speakers. Your role as a Verifier is central to minimizing errors and enhancing the reliability of AI outputs. You will review transcriptions that are brief but critically important for training accuracy. The success of the project depends on your ability to apply guidelines consistently and communicate feedback effectively. By participating, you help ensure that AI models treat Portuguese with the same rigor as other major languages. The work is demanding but offers a unique chance to influence the development of responsible AI systems.

Your core responsibility is to verify that transcriptions match the spoken content in audio files accurately. You will assess each segment against detailed guidelines that govern punctuation, capitalization, and stylistic choices. When discrepancies are found, you must reject the transcription and document the exact nature of the error in written form. This feedback loop is essential for training transcribers to improve over time. You will also support Analysts by highlighting patterns that could affect data integrity. Your reviews contribute to the creation of a clean, reliable dataset that strengthens the AI's ability to understand natural Portuguese speech. Through this process, you help reduce misinterpretations that could arise from poor transcription quality. Your role ultimately ensures that the language model learns from high-quality, accurate input.

To be eligible for this position, you must possess a command of Portuguese that is native or near-native in both spoken and written forms. Your written expression must reflect expert-level grammar, punctuation, and stylistic precision. Previous experience in roles involving quality review, editing, or transcription QA is mandatory.
