Jonathan Bischof is an ML engineer and PhD statistician with nine years of experience building production-ready machine learning systems across Google, Facebook, Cohere, and now Microsoft AI. He specializes in applied ML for generative models, code generation, and search/ranking, and has extended the Keras ecosystem with domain-specific components for state-of-the-art NLP and vision. His work blends research rigor—novel statistical models from his Harvard PhD—with practical engineering, contributing backend text-generation utilities to the popular keras-hub project. At Facebook he led embedding-based retrieval and representation learning for Marketplace search, and at Cohere focused on synthetic data and code generation at scale. Based in Seattle, he combines deep probabilistic insight with large-scale software delivery, often surfacing subtle evaluation and sampling strategies that improve real-world model behavior.
