- Label or classify content based on project guidelines.
- Identify and flag factually incorrect, sensitive, inappropriate, or unclear material.
Requirements
- You hold or are currently pursuing a Bachelor’s, Master’s or PhD Degree in any professional field.
- You have advanced proficiency in Portugese (C1) and at least English (B2), both written and spoken.
- Experience in QA, editing, teaching, consulting, or reviewing work in a professional or academic setting, including mentoring or training others (e.g., onboarding junior staff, conducting workshops, reviewing peer work).
- Excellent written communication and ability to give clear, structured and constructive feedback
- Proven experience in annotation or data labeling.
- Attention to details and ability to understand and follow instructions.
- Genuine interest in technology and artificial intelligence.
