Ai Ml Data Scientist @Turing

Palo Alto, CA, US

Currently working as an AI/ML Data Scientist (Contract) at Turing, contributing to high-impact projects at the frontier of artificial intelligence. I specialize in evaluating and enhancing large language models (LLMs) through structured prompt development, reasoning assessment, and Retrieval-Augmented Generation (RAG) pipelines.My work includes crafting complex analytical tasks to test model capabilities across reasoning, abstraction, coding, and factual grounding. I collaborate with research teams to benchmark LLM behavior and design datasets that surface model strengths, weaknesses, and ethical considerations. Actively contributing to LLM testing pipelines (reasoning, math, multilinguality)Strong focus on prompt engineering and quality annotation for model alignmentSkilled in analyzing hallucinations, factual consistency, and edge-case behaviorCross-functional collaboration with AI labs and Turing’s model partnersCommitted to model safety, interpretability, and performance transparency
