We are seeking a Machine Learning Engineer with at least 3-4 years of software engineering and ML systems experience to join our collaborative Machine Learning Engineering Team at Proofpoint.
This role is integral to designing, building, and scaling production ML systems for cybersecurity challenges.
You will take ownership of the full ML lifecycle—from data pipelines and feature engineering to model training, serving, and monitoring at scale.
You will work closely with data scientists, data engineers, and security teams to build robust, performant systems that detect and prevent cyber threats in real time.
What You Bring to the Team
As a core team member, you will play a crucial role in architecting scalable ML systems and ensuring production excellence.
You will own the end-to-end development and deployment of ML models, from infrastructure design to optimization and monitoring.
You work closely with data scientists, MLOps engineers, data engineers, and security specialists to ensure models scale, perform reliably, and integrate seamlessly into our production environments.
Day-to-Day Responsibilities
Design and build scalable ML pipelines and data infrastructure for high-throughput threat detection systems.
Own the end-to-end deployment and monitoring of ML models in production, including A/B testing and performance optimization.




Architect model serving solutions (REST APIs, batch prediction, streaming) that meet latency and throughput requirements.
Build feature pipelines and data infrastructure to support model training and inference at scale.
Collaborate with data scientists to understand model requirements and translate them into production systems.
Implement monitoring, logging, and alerting for ML models in production to detect performance degradation and failures.
Optimize model performance and resource utilization, managing compute costs and inference latency tradeoffs.
Actively engage with the team including data scientists, engineers, ML platform specialists, security analysts, and product management to deliver robust solutions.
Desired Skills & Experience
Strong software engineering fundamentals: proficiency in Python, solid understanding of data structures, algorithms, and system design.
Experience building ML systems end-to-end: data pipelines, feature engineering, model training, model serving, and monitoring.
Hands-on experience with ML frameworks: PyTorch, TensorFlow, or Scikit-learn in production settings.
Familiarity with ML deployment and serving frameworks: MLflow, TensorFlow Serving, KServe, or similar.
Familiarity with goLang
Experience with cloud platforms, particularly AWS (EC2, S3, SageMaker, Lambda, RDS) for building scalable systems.
Understanding of software engineering best practices: testing, CI/CD, code review, and version control.
Basic understanding of adversarial ML concepts and security analytics is a plus.
