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.

What You Will Need:

• A proven track record for mentoring technical members in a professional setting.
• A deep understanding of recent deep learning, LLM and natural language processing algorithms and architectures.
• Fluency in the Python machine learning life cycle: designing, developing, deploying, and maintaining models in production.
• Proficiency in Linux commands, version control, unit testing, and containerization.
• A strong grasp of machine learning algorithms, both unsupervised and supervised.
• Concrete rhythms for staying current with the rapidly evolving field of machine learning.
• The ability to communicate concisely with a non-technical audience.
• The ability to collaborate frictionlessly with a wide range of technical collaborators, both inside and outside the team.
• The ability to manage several projects simultaneously, including scoping technical tasks and effectively communicating progress toward milestones.
• Passion for learning new skills and technologies.

What Will Help:

• Previous professional experience at a SaaS company.
• Knowledge of infrastructure-as-code tools such as CloudFormation or Terraform and public cloud services such as AWS or Azure.
• A graduate degree in Statistics, AI, Machine Learning, Computer Science, or technical field.
• Interest in computer, network, or email security.
