About The Team

Proofpoint Labs is an internal machine learning group that consults across Proofpoint's entire product portfolio. We are a group of data scientists and engineers who love keeping up with the latest ML research, fostering a collaborative and creative workplace, and solving challenging problems. Over the past several years, we have developed data-driven product features, leveraging a range of model architectures from tree-based models to state-of-the-art transformers. The projects have spanned the full range of modern ML techniques (deep and classical learning), approaches (supervised and unsupervised learning) and data types (textual, image, and structured data). Each new project surfaces novel puzzles to be solved, while production deployments to our cloud ML Platform expose new MLOps challenges. Recently, our organization began spearheading company-wide initiatives around large language models and their application to the business by creating resources, putting together project teams, and organizing hack days.

We are a growing team with many opportunities for ownership and impact, guided by our four values

• Human Beings, Not Human Doings We bring our whole self into every part of our work. We possess worth and value beyond our code.
• Humble But Confident We are confident in our current abilities while celebrating the strengths of our team and our own areas for growth.
• Openly Collaborative We strive for pristine documentation, transparent chat rooms, and realistic management of tech debt and tribal knowledge.
• Impactful Innovators We seek and scope meaningful work that we approach creatively but efficiently.
