Sr. Data Scientist (Remote)

About The Role

CrowdStrike is seeking an exceptional Senior Data Scientist to join our NGSIEM Agentic AI team. In this role, you will design, build and deploy advanced AI systems that analyze and prioritize millions of security events per second, enabling organizations to rapidly identify and respond to emerging threats. You will develop intelligent models for anomaly detection, event classification, ranking, correlation, and automated security reasoning. As a key contributor, you will take ownership of complex technical challenges, drive innovation across the AI stack, and help shape the next generation of AI-powered security operations.

What You'll Do

• AI, Search & Retrieval Strategy: Lead the architecture and technical strategy for large-scale retrieval, ranking, vector search, RAG, and anomaly detection systems operating at enterprise scale. Drive innovation across LLMs, AI-powered discovery, personalization, and autonomous AI workflows. Define the future direction of AI-driven reasoning, ranking and investigation capabilities across the platform.
• AI/ML Architecture & Technical Leadership: Own end-to-end AI/ML architecture, including data pipelines, feature engineering, model development, deployment, monitoring, evaluation, and continuous improvement. Establish scalable architecture patterns, engineering standards, experimentation frameworks, and operational best practices across multiple teams. Drive foundational investments and technical direction across AI platforms, retrieval infrastructure, model-serving systems, and ML tooling. Balance model quality, customer experience, latency, scalability, reliability, security, and infrastructure cost when making architectural decisions.
• Product & Business Impact: Define evaluation methodologies, experimentation strategies, and success metrics to assess product, model, and business impact. Partner closely with Product, Engineering, Security, Infrastructure, and Operations teams to identify high-value opportunities and deliver scalable AI solutions. Communicate technical trade-offs, recommendations, and results clearly to both technical and executive audiences.
• Technical Leadership: Lead highly ambiguous, multi-quarter initiatives spanning Product, Engineering, Data Science, and other stakeholders. Influence organization-wide technical strategy, investment priorities, and long-term AI roadmap decisions. Represent the organization in executive reviews and drive alignment on major technical and product initiatives. Mentor junior scientists while fostering a culture of technical excellence and innovation.
