Bold in how we dream and innovate

Responsive to feedback, challenges and opportunities

Accountable for results and best in class outcomes

Visionary in future focused problem-solving

Exceptional in execution and impact

Corporate Overview

Proofpoint is a leading cybersecurity company protecting organisations’ greatest assets and biggest risks: vulnerabilities in people. With an integrated suite of cloud-based solutions, Proofpoint helps companies around the world stop targeted threats, safeguard their data, and make their users more resilient against cyber-attacks. Leading organisations of all sizes, including more than half of the Fortune 1000, rely on Proofpoint for people-centric security and compliance solutions mitigating their most critical risks across email, the cloud, social media, and the web.

We are singularly devoted to helping our customers protect their greatest assets and biggest security risk: their people. That is why we are leaders in next-generation cybersecurity.

The Role

Proofpoint is looking for a Senior Data Scientist to join our Machine Learning team. In this role, you'll drive the evolution of our email threat detection engine, which protects some of the largest enterprises globally, from sophisticated email-based threats.

You will collaborate cross-functionally and lead major initiatives end-to-end ensuring that we apply state-of-the-art machine learning techniques to identify and solve the most impactful problems. You will also help promote machine learning best practices and encourage innovative approaches to problem-solving within the team.

Key Responsibilities

Extract and derive actionable insights from massive volumes of unstructured email datasets using distributed computing tools (Spark, Iceberg, Athena) and AWS SageMaker

Engineer features that capture communication behaviors and patterns across billions of email records, translating domain expertise into scalable feature pipelines

Fine-tune LLMs for domain-specific tasks (email topic detection, NER) and train neural network models from scratch on massive volumes of email data to identify anomalous patterns and behaviors indicative of malicious threats

Apply classical machine learning techniques (e.g., boosting, bagging) to train models that classify large volumes of imbalanced datasets with low-latency inference

Deploy trained models to production using AWS SageMaker, directly impacting the effectiveness of our core threat detection products

Partner with Product and Engineering teams to identify high-impact research areas and drive data-driven decision-making

Mentor junior data scientists and drive adoption of ML best practices, fostering a culture of experimentation and continuous learning

Evaluate emerging machine learning and AI advancements, and integrate promising techniques into our threat detection solutions

What We're Looking For

Experience leading high-impact machine learning projects with demonstrated results in production environments

Deep expertise in neural network architectures with proven experience applying them to real-world problems. Experience with graph neural networks or advanced fraud detection techniques is highly desirable

Proficiency with one or more deep learning frameworks (PyTorch, TensorFlow, JAX). Experience with PyTorch Geometric or DGL is a plus

Hands-on expertise with gradient boosting frameworks (XGBoost, CatBoost, LightGBM) for imbalanced classification tasks

Experience monitoring and maintaining model performance in production, including detection and mitigation of model and data drift

Experience leveraging LLMs and agentic workflows for research and problem-solving is a plus

A collaborative mindset with genuine passion for high-impact work and a commitment to fostering innovative thinking within the team

Strong listening skills; open to input from other team members and departments
