About the Role:

CrowdStrike Falcon protects customers with a lightweight endpoint sensor that observes system activity, blocks malicious behavior, and streams telemetry to the Falcon cloud for correlation across the fleet. Reliable telemetry is what makes all of this possible.

This is a Principal Software Engineer role and the senior technical architect for sensor telemetry and observability. You will own the architecture and direction for how the sensor collects, transports, and surfaces reliability data end-to-end — from the on-endpoint collection SDK through cloud ingestion and analytics — across Windows, macOS, and Linux. This is a builder's role with significant greenfield scope and broad technical influence across the sensor organization.

What You'll Do:

• Own the architecture and technical strategy for a unified telemetry and observability platform, from endpoint collection SDK to cloud ingestion, decode, and analytics.

• Design for the realities of the endpoint: crash-survivable in-memory telemetry, resource-constrained collection, priority stream separation, and performance-sensitive paths.

• Drive structured logging and data governance — type safety, PII auditability, and privacy compliance for telemetry collected at scale.

• Evolve the platform without breaking existing consumers, and serve as the connective technical authority for telemetry across multiple teams.

• Own designs from concept through shipped code, on-endpoint and in-cloud, with cross-platform deliverables.

• Lead, mentor, and raise the technical bar across a distributed engineering team.

What You'll Need:

• Deep, hands-on experience architecting at-scale telemetry, observability, or crash-reporting platforms end-to-end — agent SDK through cloud ingestion and analytics — with systems you designed running in production.

• Strong low-level and systems engineering in C/C++, with a track record of performance-sensitive, resource-constrained design.

• Experience with structured logging, telemetry data governance, and privacy/PII handling at scale.

• A record of shipping and evolving platforms without breaking consumers, and of influencing technical direction across teams.

• Strong debugging fundamentals: crashes, memory issues, contention, and system performance.

• Ability to lead, mentor, and collaborate in a distributed team.

• Proven experience utilizing AI technologies to enhance decision-making, streamline workflows and processes, improve efficiency and drive business outcomes.

Bonus Points:

• Scalable, lightweight, high-performance systems and OS internals across more than one platform.

• OS-level performance and diagnostic instrumentation (e.g., ETW, PMU/hardware telemetry).

• Data lake and analytics stacks (KQL, SQL, Snowflake) and Go-based cloud services.

• Endpoint security domain knowledge; comfort in an Agile, frequently-shipping team.
