Senior Security Research Engineer

What you'll do

• Research emerging attacker techniques to design and ship new security protections.
• Instrument new event sources across Windows, macOS, and Linux to deepen endpoint telemetry.
• Write performant, stable C/C++ code for production use on millions of endpoints.
• Reverse engineer malware to identify and mitigate evasion tactics used by malicious actors.
• Monitor customer telemetry at scale to investigate false positives and performance regressions.
• Extend protection parity and support for new hardware architectures across all operating systems.
• Lead technical direction by managing multi-release initiatives and mentoring junior engineers.
• Publish research findings and present security findings at industry conferences.

What we're looking for

• 6+ years of professional experience analyzing attacker TTPs and building detection methods for real security threats.
• 6+ years of development experience in C, C++, and Python for security-critical codebases.
• Deep operating system internals knowledge in kernel and user mode, with a focus on Windows.
• In-depth reverse engineering and malware analysis experience using tools to make hard binaries readable.
• Proven track record of using AI to accelerate development, debug complex systems, and optimize code.
• Vulnerability research and exploit development experience, particularly with a track record of responsible disclosure (preferred).
• Red teaming experience or a background in building offensive tooling and defeating endpoint security products (preferred).
• Kernel-mode development, including driver development and debugging (preferred).
