I performed RLHF safety annotation, adversarial red teaming, and model response scoring under Project Neon guidelines for an AI safety contract. My work involved evaluating and annotating paired model responses for policy compliance, refusal accuracy, and content risk. I also engineered prompts to probe model boundaries and reported nuanced findings with detailed justifications. • Earned recognition for work quality (Nova Badge) and received additional hours. • Annotated sensitive content and categorized model responses across numerous high-risk topics. • Provided severity ratings, preference rankings, and fact-checked citations per response. • Conducted routine quality assurance reviews and maintained high annotation standards.
