Requirements
- At least 6 years of experience in data science or machine learning, using programming languages such as Python or R to build and deploy models in production environments; cybersecurity, fraud, or risk domain experience is preferred.
- At least 4 years of experience working with security-relevant datasets and tools, such as Security Information and Event Management platforms, endpoint protection, identity and access data, or network telemetry, in an enterprise environment.
- Strong understanding of statistical modeling, feature engineering, and model evaluation techniques, including handling class imbalance in threat and fraud detection use cases.
- Experience building and maintaining data pipelines that ingest, transform, and operationalize large-scale structured and unstructured data.
- Ability to translate complex analytical findings into clear, actionable insights for technical and non-technical audiences.
- Bachelor's degree in Computer Science, Data Science, Statistics, or a related field, or equivalent professional or military experience.
Responsibilities

- Engineer security data pipelines for ingestion, cleansing, feature engineering, and model monitoring using structured and unstructured cyber data sources such as logs, alerts, network flows, and endpoint data.
- Analyze outputs from security tools and platforms to identify control gaps, policy deviations, and emerging threat patterns, and translate findings into prioritized remediation recommendations.
- Partner with cybersecurity engineering, the Security Operations Center, and infrastructure teams to embed artificial intelligence and advanced analytics into security controls, playbooks, and incident response workflows.
- Evaluate model performance, analyze bias and drift, and continuously tune models to improve detection efficacy while minimizing false positives.
