Job description

Overview

As a global leader in cybersecurity, CrowdStrike protects the people, processes and technologies that drive modern organizations. Since 2011, our mission has been to stop breaches and we’ve redefined modern security with the world’s most advanced AI‑native platform.

About the Role

You’ll be joining our macOS Sensor Foundation team supporting CrowdStrike’s flagship Falcon endpoint protection platform. The team is responsible for core sensor components in user space (C++, Swift). We build and maintain the macOS sensor, creating and/or building a platform for products and features that empower customers with prevention, detection, and response capabilities.

Location: This role is hybrid, requiring 2‑3 days per week on‑site at one of the posted locations.

What You’ll Do

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 an Engineer3 – macOS Engineer role that delivers the sensor (lightweight agent) on macOS. Engineers 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 Windows and Linux.

Responsibilities

• Design and develop software for deployment on macOS systems.
• Own features from design to delivery.
• Collaborate with multi‑functional teams in various physical locations.
• Troubleshoot issues with the product as reported from customers responsively.
• Participate in other projects as assigned.

What You’ll Need

Can develop high‑quality code in C/C++ and Swift, and can demonstrate that capability, through job experience, schoolwork, or contributions to community projects.

Experience on macOS developing product code with the following characteristics:

• High concurrency requirements needing strong use of multi‑threading.
• High reliability requirements with detailed requirements on low‑level operating characteristics (memory usage, efficient performance, correct conformance to external standards).

Experience working on a team to ship major features and releases.

Able to communicate, collaborate, and work effectively 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

• Prior experience working on Endpoint products, Cyber Security space, or networking technologies (e.g., network security, network protocols, or network infrastructure).

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.
