Sr. Software Engineer II, Sensor - Sensor Event Runtime

Experience: Not Available to Not Available years

Location: Sunnyvale, CA, USA

Skills: C, C++, Windows, Mac, Linux, kernel mode development, concurrency primitives, resource acquisition patterns, thread safety, low-latency performance, Python, Pytest

About the Role
We're building a welcoming & flexible team that prizes collaboration over competition, one which provides opportunities to learn new skills, mentor junior and senior developers and contribute to the direction of both the team & the products we're responsible for. This is a high trust environment where we allow team members to manage their own time, take holidays as they need it and reward them with competitive salaries and equity. CrowdStrike is seeking a Senior Software Engineer II to join our Sensor Event Runtime (SER) team. This role is responsible for the design and implementation of high-performance software components in CrowdStrike's endpoint security solution — handling storage, correlation, filtering, rate limiting, and deduplication for event processing systems to ensure our customers are secure. You'll be designing and troubleshooting low-latency C and C++ code across Windows, Mac, and Linux, and your expertise in kernel mode development, concurrency primitives, and resource acquisition patterns will directly drive the performance of our event pipelines.

What You'll Do
Design, develop, and test high-performance, cross-platform C and C++ code for Windows, Mac, and Linux.
Collaborate with cross-functional teams to integrate new features into the Falcon sensor.
Troubleshoot complex issues related to kernel mode development and low-latency systems.
Develop solutions that emphasize thread safety, resource efficiency, and low-latency performance.
Be an energetic self-starter with the ability to take ownership and be accountable for deliverables, both individually and when leading a team.
Deliver and accept feedback with grace and courtesy.
Focus on continual learning, raising the bar for both yourself and your teammates.
CrowdStrike is a computer security company, but we do not require candidates for this role to have prior security industry experience. We will mentor and train in security topics as needed.



We do expect a solid interest in CrowdStrike's mission and a willingness to engage with the needs of our product teams and customers.

What You'll Need
Proven track record of successfully delivering complex software projects.
Advanced C/C++ proficiency, including design patterns.
Kernel Mode Development: Demonstrated experience with kernel mode development on at least one platform (e.g., Windows, Linux).
Cross-Platform Development: Proficiency developing sophisticated software across multiple operating systems (Windows, Mac, Linux), with expertise utilizing cross-platform libraries and build systems.
Process Management & IPC: In-depth understanding of process creation, synchronization, and communication mechanisms.
Concurrency Primitives & Resource Acquisition: Expertise in developing concurrent code using synchronization primitives and extensive experience with resource acquisition patterns (e.g., RAII, lock-free data structures).
Memory Management & Performance Optimization: Comprehensive knowledge of memory management techniques (paging, virtualization, etc.) and extensive experience with performance optimization techniques (profiling, caching, etc.).
A strong sense of ownership — your team owns the code and the future of these components.

Bonus Points
Windows Kernel Experience: Deep experience developing kernel-mode drivers or system software, with a comprehensive understanding of Windows kernel internals and API usage.
High-Throughput Event Pipelines: Experience designing and implementing high-throughput event processing systems.
Python Scripting & Testing: Proficiency with Python and its ecosystem, including experience with testing frameworks such as Pytest.
