• Provide clear, structured feedback to improve downstream AI training quality
• Maintain high accuracy across repetitive, high-volume workflows
• Flag unclear instructions or ambiguous cases proactively

What We're Looking For

• Exceptionally detail-oriented and quality-obsessed mindset
• Prior experience as a CB/reviewer/rater in human data or AI training pipelines
• Proven ability to follow nuanced instructions without deviation
• Strong written communication and reasoning skills
• High reliability, consistency, and comfort with repetitive precision work
• Ability to work independently and maintain focus over long task batches

Nice to Have

• Experience with large-scale AI data annotation or evaluation programs
• Background in QA, operations, trust & safety, or structured review work
• Familiarity with multi-step rubric-based evaluations
• Comfort giving calibrated feedback aligned with strict quality bars

Why Join

• Work directly on training next-generation AI systems
• Clear expectations and quality-first culture
• Long-term opportunity for consistent, high-quality contributors
