This role combines modern Python engineering, advanced analytics, and responsible AI practices to strengthen security outcomes at scale.
What you will do:
- Build and maintain Python-based AI and machine learning applications supporting threat detection, risk scoring, operational analytics, and intelligent automation.
- Develop reusable Python modules, APIs, and services for cyber data ingestion, feature engineering, and model execution.
- Partner with cybersecurity engineering, threat analysts, and platform teams to operationalize ML pipelines within enterprise data platforms and security tooling.
- Analyze structured and unstructured cybersecurity data (logs, alerts, network telemetry, identity data, behavioral signals) to generate insights and identify automation and detection improvements.
- Evaluate, validate, tune, and monitor models to meet performance, reliability, and governance requirements.
- Apply MLOps practices to support model lifecycle management, monitoring, and versioning in controlled environments.
- Document technical designs, workflows, and processes to support transparency, reproducibility, and operational readiness.

- Experience integrating machine learning components into production systems or enterprise platforms.
- Strong understanding of algorithms, statistical methods, and machine learning evaluation techniques.
- Experience with cloud services such as GCP, AWS, or Azure.
- 6–10 years of an equivalent combination of educational background, related experience, and/or military experience.
What would be great to have:
- Hands-on experience developing ML models for NLP, anomaly detection, clustering, or graph analytics in security contexts.
- Exposure to MLOps and model governance tooling (e.g., MLflow, Kubeflow, SageMaker, Databricks, Azure ML).
- Experience building or integrating APIs, microservices, or automation frameworks in cybersecurity environments.
- Understanding of MITRE ATT&CK, threat intelligence workflows, or adversary behavior modeling.
- Experience working with cybersecurity telemetry/datasets (SIEM logs, EDR alerts, identity events, network flow data, vulnerability data).
- Familiarity with threat detection, behavior analytics, identity security, or risk scoring concepts.
- Experience with security tools/platforms (e.g., Splunk, CrowdStrike, Tanium, Sentinel, Chronicle).
- Background in the financial services industry.
- Relevant certifications (e.g., Security+, CySA+, AWS Machine Learning Specialty, GCTI, or other data/AI/cyber credentials).
