About the Role
You will design and build machine learning systems that power enterprise search, retrieval, recommendations, and AI agents. You will develop evaluation frameworks and metrics to measure the quality, performance, and business impact of LLM-powered applications, and build scalable data and ML pipelines that process large-scale AI interaction data. You will apply statistical modeling, experimentation, and causal inference to guide product development, analyze product usage and customer behavior, and prototype, evaluate, and deploy new AI capabilities using foundation models, embeddings, and retrieval-augmented generation techniques. You will define key performance indicators and build analytical frameworks that inform product strategy, while mentoring junior team members and establishing best practices across data science and machine learning.
