Machine Learning Engineer - Fraud Risk

Design, build, and operate production machine learning systems that detect and prevent fraud, from data ingestion and feature engineering through model training, deployment, and continuous monitoring.

Responsibilities

• Architect and build scalable ML systems for fraud detection, anomaly detection, and behavioral analysis
• Develop and maintain end-to-end ML pipelines including data ingestion, feature engineering, model training, deployment, and monitoring
• Design and implement low-latency real-time decision systems using transaction and behavioral data streams
• Own ML infrastructure including model versioning, automated retraining, and safe deployment strategies
• Build monitoring and alerting for model performance, latency, data quality, and drift
• Lead experimentation on model explainability, drift detection, and adversarial robustness
• Develop tooling and processes to improve the ML development lifecycle
• Partner with platform teams to meet SLAs for availability, latency, and accuracy
• Collaborate with engineers, data scientists, and compliance teams

Requirements

• 5+ years of experience building ML systems in production, including 2+ years in fraud, risk, or anomaly detection
• Degree in Computer Science, Engineering, Statistics, Applied Math, or a related technical field
• Track record designing and maintaining ML models at scale
• Advanced proficiency in Python and ML frameworks such as PyTorch, TensorFlow, and scikit-learn
• Strong understanding of supervised learning, unsupervised learning, anomaly detection, and statistical modeling
• Ability to work autonomously, manage ambiguity, and collaborate with data scientists
• Experience productionalizing predictive real-time and offline fraud detection models
• Experience collaborating with cross-functional teams to deploy ML solutions at scale
