About the Role:

\n

This is a full stack backend engineering position on the Spotlight platform team. You will design, build, and operate the cloud-native services and infrastructure that power CrowdStrike's endpoint vulnerability assessment capabilities at global scale. This role requires a strong focus on distributed systems, service reliability, scalability, and cloud architecture across AWS and GCP.

\n

\n

This role also requires reasoning and judgment over large volumes of continuously changing data, at the scale CrowdStrike operates — work that conventional rule-based systems have only partially addressed. We're treating agentic reasoning as a core architectural element rather than a feature layered onto an existing system, which means real decisions are still open: where reasoning belongs, where determinism is the better answer, and how to make either hold up in production.

\n

The Product and Platform:

\n

\n

Falcon Vulnerability Assessment is the industry's first scan-less endpoint vulnerability assessment solution, delivering real-time, zero-impact assessments of endpoint security posture. Falcon Vulnerabiity Assessment adds preparation and readiness to the unparalleled prevention, detection and response provided by the Falcon platform, resulting in a stronger security posture and unprecedented breach protection.

\n

\n

CrowdStrike Falcon is a two-component security product. One component is a "sensor", which is a lightweight agent installed on client machines that observes system activity and recognizes malicious behavior, then provides on-box prevention capability and remote telemetry to the Falcon cloud. The cloud component aggregates sensor telemetry for each customer's network, can correlate malicious behavior across multiple machines, and presents our customers' operations teams with a prioritized summary of the threats detected in their environments.
