Sr. Software Engineer, Windows Sensor - CTIO; Hybrid

About the Role

Crowd Strike Falcon Host is a two‑component security product. One component is a “sensor”: a driver installed on client machines that observes system activity and recognizes malicious behavior, then provides on‑box prevention capability and remote telemetry to the Falcon Host cloud. The sensor processes thousands of events per second to provide deep visibility into operations on the endpoint, and performs rich correlation and computation to identify malicious events and block malicious activity.

The cloud component aggregates sensor telemetry for each customer’s network, correlates malicious behavior across multiple machines, and presents our customers’ operations teams with a prioritized summary of the threats detected in their environments.

As a Senior Software Development Engineer (SDE) in the CTIO team, you will design and develop core features for the lightweight agent that runs on critical Windows OS platforms. Features will cross‑cut core operating‑system subsystems such as file system, memory, process, and networking, and many will share components across Linux and Mac. The team follows Agile principles and ships frequently.
