You will leverage large volumes of cybersecurity and operational data to create models that enhance our Managed Detection and Response (MDR) capabilities, including anomaly detection, threat scoring, and automated alert triage. You'll work closely with Security Operations, Product, and Data Engineering teams to translate complex security challenges into data science problems, ensuring our AI/ML solutions are effective, scalable, and directly contribute to our clients' security outcomes. This role combines deep analytical rigor with practical engineering to deliver mission-critical AI for cybersecurity., AI/ML Model Development * Design, develop, train, and deploy high-performance machine learning models for critical security tasks such as threat detection, anomaly scoring, and behavioral analytics. * Conduct feature engineering and selection on vast, high-velocity streams of security data (logs, network telemetry, endpoint data). * Own the model lifecycle, including versioning, rigorous testing, and continuous improvement through MLOps best practices. Research & Innovation * Stay up-to-date on state-of-the-art research in data science, deep learning, and security-specific AI to drive platform innovation. * Explore novel statistical methods and machine learning techniques to tackle emerging and sophisticated cyber threats. * Design and implement A/B testing and evaluation frameworks to measure the impact and performance of deployed models. Data & Feature Engineering * Partner with Data Engineers to define, preprocess, and structure large, complex datasets for model training and inference. * Implement and manage data pipelines specifically for feature extraction and model serving. * Leverage vector databases and RAG (Retrieval-Augmented Generation) pipelines for enhanced security context and large language model applications. Cross-Functional Collaboration * Work closely with Security Operations to understand real-world threat landscapes and ensure model outputs are actionable and integrated into workflows. * Collaborate with Product Managers to define AI features and translate model performance into measurable business value. * Present complex analytical findings and model behavior clearly to technical and non-technical audiences. ## Related Videos - [Data Science in Retail](https://www.wearedevelopers.com/videos/586-data-science-in-retail) - [From Messy Queries to Scalable Systems - How Data Engineering actually works](https://www.wearedevelopers.com/videos/100203-from-messy-queries-to-scalable-systems-how-data-engineering-actually-works) - [Advanced Typing in TypeScript](https://www.wearedevelopers.com/videos/496-advanced-typing-in-typescript) - [Vectorize all the things!
