Software Engineer (L6), Platform Security

Implement security enhancements using a variety of methods such as kernel and user-space development, configuration changes, or leveraging hardware-based security features such as TPMs and hardware offload. Analyze and triage new system-level security bugs, including hardware/GPU and OS isolation issues and provide appliance security expertise during incident response. Develop automated systems and low-level tooling to perform vulnerability research and reduce manual security overhead in build, test, and release workflows. Proven track record of architecting and implementing security features that meaningfully improve system security. Deep expertise in low-level systems and hardware security across a heterogeneous stack (kernels, firmware, BMC, BIOS/UEFI, FPGA). Experience using operating system execution environments such as containers or virtual machines to enhance security. Success at partnering with others to improve the security posture through cross-functional changes. Experience using AI agents to automate security research. Experience conducting security research, with published materials to show for it. Experience conducting penetration tests which found meaningful opportunities for improvement and identified security gaps. Kernel development experience. Experience successfully using TPMs/HSMs, trusted execution environments, and other hardware features. Experience with measured/secure boot and hardware roots of trust. Experience working on highly distributed systems and fuzzing complex systems. Experience securing FreeBSD, Linux; familiarity with GPU/virtualization isolation. Experience with C, Golang, Python.
