This role works closely with data engineers, security researchers, and threat intelligence analysts to operationalize machine learning models that directly support threat hunting detection and automated defense., * Design, develop, and deploy machine learning models in collaboration with security researchers and threat intelligence analysts to identify and validate malicious actors and behaviors across large-scale network telemetry.

• Work with petabyte-scale datasets and distributed data platforms to operationalize ML models in production environments supporting real-time or near-real-time detection.
• Collaborate with threat intelligence analysts and security researchers to translate attacker TTPs into scalable ML-driven detections.
• Build data pipelines and feature engineering workflows that enhance intelligence datasets with more actionable insights and context.
• Document models, methodologies, and results for internal stakeholders.

Ideally, we’re looking for someone that has a strong background in software development that exhibits:

• Strong programming skills in Python with experience building production-grade ML pipelines.
• Experience working with large-scale or distributed data systems (e.g., Spark, Hadoop-based ecosystems, or similar)
• Understanding of data structures, algorithms, and statistical analysis.
• A strong desire to learn and play with new technologies and techniques.
• Experience with iterative development methodologies and practices.

The following are not required, but are things that we look for to raise resumes up to the top of our stack:

• Experience applying ML in cybersecurity, threat intelligence, threat detection, or network analysis domains.
• Familiarity with graph analytics, network flow data, or internet infrastructure modeling.
• Exposure to MLOps practices, model monitoring, and production deployment at scale.
• Background working alongside security analysts, reverse engineers, or security research teams.
