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.

Working close to the OS layer, you will build advanced runtime monitoring capabilities under strict stability and performance constraints. Our products are built in Rust, and each engineer owns a core component end-to-end, from architecture and implementation to production deployment and optimization. This role offers the opportunity to tackle complex systems challenges, work with cutting-edge technologies, and build innovative solutions within Linux and Windows environments.

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.

Job Requirements

• 5+ years of experience in low-level software development (Rust/Go/C/C++).
• Strong understanding of Linux and Windows internals, including memory management, processes, and syscalls.
• Experience with scripting languages such as Python and Bash.
• Team player with strong communication and collaboration skills.
