AI Safety & Data Quality Analyst (HITL) - Washington

Join the Human Intelligence Behind the World’s Leading AI – Washington

 

Are you sharp, curious, and obsessed with the details? Welo Data is looking for Data Quality Analysts who can go beyond simple labels to help define how AI should behave in the real world.

This is a Human-in-the-Loop (HITL) role where your judgment is the product. You won't just be following guidelines—you’ll be refining them, identifying failure modes, and ensuring that the next generation of AI is safe, accurate, and helpful.

The Mission: Beyond Annotation

• Model Evaluation : Critique AI outputs and provide structured, high-level feedback that drives model improvement.
• Safety Engineering : Use your 2+ years of GenAI safety experience to identify bias, risks, and edge cases.
• Trend Analysis : Spot patterns in how models fail and communicate these insights to stakeholders.
• Framework Architecture : Don’t just execute workflows—help improve the evaluation frameworks themselves.
• Collaborative Calibration : Partner with leads and cross-functional teams to set the gold standard for AI quality.
