Ready to join a mission that matters? The future of cybersecurity starts with you.

The Crowd Strike Detection Engine (CDE) team is building a powerful, next‑generation platform designed to be a force multiplier for security teams. Our platform empowers customers who leverage multiple Falcon products to create and manage advanced, unified detections and content. This core platform capability is a strategic imperative for Crowd Strike, aiming to provide a competitive advantage that is difficult to replicate, ensuring our customers have unparalleled detection and response capabilities across the entire Falcon ecosystem.

We are seeking a highly experienced and motivated Sr. Backend Engineer to join the CDE Platform team. In this role, you will be instrumental in designing, building, and scaling the foundational services that orchestrate data, content, and execution logic across Crowd Strike’s products (e.g., NGSIEM, FCS, Endpoint). You will be a key driver in creating a highly performant, scalable, and resilient platform that processes internet‑scale data streams and enables real‑time detection generation.

This is a hybrid role based out of our office in NYC. Candidate should be comfortable visiting the office twice a week once the development center is established.
