SDET III, Windows Sensor (Remote)

OverviewCrowdStrike, Inc. — Full time As a global leader in cybersecurity, CrowdStrike protects the people, processes and technologies that drive modern organizations. Since 2011, our mission has been to stop breaches with the world\'s most advanced AI-native platform.

We process large scale distributed systems and handle massive event throughput. We are a mission-driven company that values autonomy and ownership of careers, and we’re always looking to add talented CrowdStrikers to the team.

About the RoleCrowdStrike Falcon Host is a two-component security product.

One component is a \"sensor\": a driver installed on client machines that observes system activity, recognizes malicious behavior, and provides on-box prevention and remote telemetry to the Falcon Host cloud.

The sensor processes thousands of events per second to provide deep visibility into endpoint operations and to identify and block malicious activity.

The cloud component aggregates sensor telemetry, correlates behavior across machines, and presents a prioritized threat summary to customers’ operations teams.

This is a Software Development Engineer in Test (SDET) position on the Windows sensor engineering team, in the detection space. SDETs at CrowdStrike collaborate with SDEs in combined engineering teams.

SDETs focus on the sensor’s quality, build tools and specialized tests, participate in design and code reviews, and collaborate with research, hunting, and cloud teams to ensure end-to-end sensor functionality.

Successful engineers in this role understand Windows kernel and user space, have a passion for continuous learning, and design new code validation methods to improve quality, performance and reliability of shipped code.
