About the Role:
CrowdStrike 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 blocks 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.
This is a Sr. Software Development Engineer (SDE) role in the CTIO team that delivers the cutting edge innovation for our sensor (lightweight agent) for macOS platforms. The Sr. SDE’s in the team own design and development of core features on the platform. Features will cross-cut most core OS subsystems such as file system, memory, process, and networking. Many features are also built in a way that they will have shared components across Linux and Windows. The team operates under the Agile development principles and ships frequently.
The CTIO team at CrowdStrike is responsible for defining and executing the company's technology vision and strategy, driving innovation and overseeing the development and evolution of the Falcon platform. The CTIO ensures CrowdStrike maintains its position as a technology leader by fostering engineering excellence, aligning technical capabilities with business objectives, and anticipating emerging threats and market trends.
