Project Perseus | Data Labeling Associate - Portuguese (Portugal) Speakers (Human-in-the-Loop AI)

What You’ll Do

• Evaluate AI model outputs and provide structured, high-quality feedback

• Perform audit-based reviews of data and model behavior — identifying patterns, edge cases, and failure modes

• Apply guidelines thoughtfully — and flag when they don’t reflect real-world scenarios

• Contribute to improving evaluation frameworks, not just executing them

• Identify trends in model performance and communicate insights clearly

• Participate in team discussions, calibrations, and stakeholder syncs

• Partner with leads and cross-functional teams to refine quality standards

• Document findings in a clear, concise, and actionable way

What We’re Looking For

• Native-level Portuguese (Portugal) language proficiency and a university degree (Bachelor’s or higher).

• B2 or superior level of English.

• 1–2 years of professional writing experience with strong, structured writing skills

• Ability to apply complex writing rules and guidelines consistently

• Strong understanding of safety considerations in GenAI data delivery, with 2+ years of relevant experience

• Strong critical thinking and attention to detail

• Ability to make sound judgment calls in ambiguous situations

• Naturally curious about AI, technology, and how systems behave

• Comfortable speaking up, asking questions, and contributing ideas

• Strong written and verbal communication skills

• Ability to stay consistent while working with evolving guidelines

• Experience in data quality, QA, annotation, or analysis is helpful — but not required
