About The Position

Welo Data is seeking Data Labeling Associates for Project Perseus.

The mission is to achieve Human-in-the-Loop Excellence by critiquing Spanish AI outputs for accuracy, fluency, and tone, providing structured feedback to drive model improvement. Associates will also use their GenAI safety experience to identify bias, risks, and failure modes in Spanish datasets, apply complex linguistic guidelines thoughtfully, and help refine evaluation frameworks to reflect real-world Spanish dialects and contexts. They will also identify trends in model performance, communicate findings clearly to technical stakeholders, and participate in team syncs to ensure consistent quality across global AI workstreams. This is a W2 Full-Time Employee position, 40 hours/week, located On-Site in New York City, with a pay rate of $34 per hour.
