Job description

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 block 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. SDEs 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.

Location

This is a hybrid role based near any of our Sunnyvale, CA (CA Bay Area), Redmond, WA (Seattle, WA Area), New York City, NY or Austin, TX offices, with an expectation of approximately two days per week in‑office to foster collaboration with other team members within the teams.

What You’ll Do

• Collaborate with all the sensor development teams, across the company, on architecture and strategic initiatives.
• Conceptualize and develop new product features.
• Provide guidance and support to development teams in designing and implementing software for cross‑platform delivery (Windows, macOS, Linux).
• Take ownership of features throughout the entire lifecycle, from initial design to final delivery, including presenting product demonstrations at the conclusion of each sprint.
• Engage in cross‑functional collaboration with teams situated in various locations.

What You’ll Need

• Deep knowledge of Swift and C/C++.
• Extensive, fundamental understanding of macOS internals, with an emphasis on security frameworks.
• Proven experience in debugging memory corruption issues, process contentions, and system performance bottlenecks.
• Demonstrated experience collaborating with teams to successfully deliver major features and releases.
• Ability to lead, mentor, communicate, collaborate, and operate effectively within a geographically distributed team.

Bonus Points

• Demonstrated strong background in developing scalable, light‑weight, and highly performing systems.
• In‑depth OS system expertise regarding core concepts and subsystems.
• Familiarity and experience utilizing Agile methodologies.
• Knowledge of security principles.

Benefits Of Working At CrowdStrike

• Market leader in compensation and equity awards.
• Comprehensive physical and mental wellness programs.
• Competitive vacation and holidays for recharge.
• Paid parental and adoption leaves.
• Professional development opportunities for all employees regardless of level or role.
• Employee networks, geographic neighborhood groups, and volunteer opportunities to build connections.
• Vibrant office culture with world class amenities.
• Great Place to Work Certified across the globe.
