QA STEM Expert (Physics, Chemistry, Biology)
We are hiring a QA STEM Expert to serve as a high-caliber quality gatekeeper for AI-generated responses to complex STEM questions. This is not traditional academic proofreading. You will evaluate whether questions truly challenge frontier AI models and whether the model outputs meet rigorous standards of factual accuracy, logical soundness, and scientific validity.

Key Responsibilities

• Review and refine STEM questions (Physics, Chemistry, Biology) to ensure they effectively test conceptual depth and challenge AI models.
• Evaluate AI-generated responses for factual accuracy, scientific correctness, logical consistency, step-by-step derivation accuracy (including math, units, terminology), absence of hallucinations, flawed assumptions, or incomplete explanations.
• Assess whether a question successfully stumps the model and classify failure modes (reasoning-based, knowledge-based, interpretation, co...
