Job Description:

As a Senior Low-Level Software Engineer on the Sensor team, you will design and optimize performance-critical software that runs directly inside large-scale customer production environments. The Sweet Sensor is at the core of our platform, providing deep system-level visibility and high-fidelity threat detection across Linux and Windows systems using eBPF and a Windows kernel driver — all while maintaining a minimal performance footprint.

Job Responsibility:

• Design, plan, and implement efficient, reusable code that powers complex applications
• Research and develop innovative approaches that strengthen our Application Security platform
• Optimize performance and resource usage in demanding customer environments
• Lead challenging projects in close collaboration with Product Managers and other software engineers
• Interface and coordinate with other R&D teams to deliver complete end-to-end solutions
