Original job description

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. Our customers span all industries, and they count on CrowdStrike to keep their businesses running, their communities safe and their lives moving forward. We're proud to work for a mission-driven company leveraging AI to transform the way we work. CrowdStrikers drive their careers through flexibility and autonomy while also being expected to contribute to a culture of responsible AI adoption, experimentation, and innovation. 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:

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 blocks 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. SDE’s 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.

The CTIO team at CrowdStrike is responsible for defining and executing the company's technology vision and strategy, driving innovation and overseeing the development and evolution of the Falcon platform. The CTIO ensures CrowdStrike maintains its position as a technology leader by fostering engineering excellence, aligning technical capabilities with business objectives, and anticipating emerging threats and market trends.

Location:

This is a hybrid role based out of our Sunnyvale, CA (CA Bay Area), Redmond, WA (Seattle, WA Area), Austin, TX, NYC or Toronto 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.
Proven experience utilizing AI technologies to enhance decision-making, streamline workflows and processes, improve efficiency and drive business outcomes.

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

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
