Senior RLHF Specialist – Medical Domain & Clinical Alignment

Scale AITextRLHF

Managed the end-to-end RLHF pipeline for a clinical LLM. My core tasks involved performing Factuality Auditing on 1,500+ complex medical prompts to identify and eliminate hallucinations in diagnostic reasoning. I conducted Pairwise Ranking (Human Preference) to align model outputs with USMLE-standard clinical protocols and safety guardrails. Additionally, I authored Golden Set responses to fine-tune the model's professional tone and adherence to medical ethics
