The Role
We are seeking an AI Knowledge Engineer to join our AI and Machine Learning organization at Proofpoint.



This role is focused on enabling AI systems to operate across distributed enterprise knowledge ecosystems by creating semantic representations, governance frameworks, and knowledge architectures that unify information while preserving ownership, lineage, and trust.

As an AI Knowledge Engineer, you will help design and build semantic knowledge systems that enable AI agents, retrieval systems, and decision-support applications to reason over complex organizational information. You will work at the intersection of knowledge representation, semantic modeling, governance, and generative AI, helping establish the foundations that allow AI systems to operate effectively across federated and distributed knowledge sources.
