About the role

As an AI Tutor for Portuguese, you will label, annotate, and record multilingual audio data to improve Grok's voice interactions and speech recognition. Your work will focus on Portuguese-language audio, including accents and cultural context, to help Grok handle spoken language more accurately. This role directly supports making Grok accessible to Portuguese-speaking users worldwide.

A typical day

A typical day involves reviewing Portuguese audio clips, applying labels and annotations using proprietary software, and recording audio inputs as needed. You will follow detailed guidelines, maintain consistency, and communicate with a small remote team to resolve edge cases. Expect to work independently and prioritize tasks to meet project deadlines.

• Experience with data annotation, labeling, or transcription, especially for audio or speech data.
• Comfortable using proprietary software and following detailed guidelines for consistent labeling.
• Strong communication skills and ability to work independently in a remote, flat team structure.
