As a global leader in cybersecurity, CrowdStrike protects the people, processes and technologies that drive modern organizations. Since 2011, our mission hasn’t changed — we’re here to stop breaches, and we’ve redefined modern security with the world’s most advanced AI-native platform. We work on large scale distributed systems, processing almost 3 trillion events per day and this traffic is growing daily.

We use an AI-first mindset as a force multiplier to proactively and continuously accelerate execution, build expertise, uncover insights, and solve complex problems. We’re always looking to add talented CrowdStrikers to the team who have limitless passion, a relentless focus on innovation and a fanatical commitment to our customers, our community and each other. Ready to join a mission that matters? The future of cybersecurity starts with you.

About the Role:

This is a systems software role on the Core Libraries team, which owns the shared Windows, Linux, and macOS libraries that the sensor depends on. Examples include libraries used to handle memory allocation, securely parse and process files, and manage threads and work items. These libraries are widely used within the sensor, and the success of this team is instrumental to the success of the overall sensor platform.

As a Senior Engineer on this team, you will design, build, extend, and maintain these libraries. You will work closely with sensor developers from all organizations within CrowdStrike to provide high-quality libraries which meet the needs of fast-paced sensor development, without sacrificing quality and reliability.

Location:

This role is hybrid, requiring 2x days per week on-site at one of the posted locations.

What You'll Do:

Work across organizations and functional teams to gather library requirements, then design, implement, and test the resulting libraries

Take end-to-end ownership of your work — from design through production validation across Windows, Linux, and macOS, including the testing and rollback story

Drive technical proposals and design docs; lead design reviews for your area and provide substantive review feedback that raises the bar for the whole team

Represent the team's technical position in cross-org planning and architecture discussions; communicate tradeoffs and risks clearly to engineering, product, and program partners

Participate in planning; help scope work, identify dependencies, and flag technical risk early

Mentor and grow more junior engineers through direct feedback, pairing, and collaborative code and design review

Investigate and resolve production incidents and complex escalations; build the team's shared knowledge of failure modes at fleet scale

Champion improvements in end-to-end testing and validation for components with strict correctness and reliability requirements

What You'll Need:

Strong foundation in systems software engineering; hands-on experience in C and C++ in a low-level systems context

Intellectual curiosity and the drive to deeply understand unfamiliar systems before
