Platform Security Engineering (Operating Systems)

Join our team as an Operating Systems Security Engineer, where you'll be responsible for hardening and securing the OS layer of our infrastructure. This hands-on role involves designing and implementing OS-level security controls, minimizing attack surfaces, and developing kernel security policies. You'll work with cutting-edge hardware and implement novel security solutions for unique environments.

• Design and implement OS-level security controls, including kernel hardening and runtime protection.
• Minimize attack surfaces by removing unnecessary components from kernelspace and userspace, and develop kernel security policies.
• Build security infrastructure for AI systems, research environments, and production services, and create OS-level attestation and integrity monitoring systems.
• Strong programming skills in C and systems programming languages
• Experience with security-focused Linux distributions
• Experience with kernel hardening techniques and exploit mitigation
• Understanding of virtualization and containerization security
• Track record of identifying and fixing OS-level security vulnerabilities
• Experience with eBPF for security monitoring and enforcement
• Deep knowledge of Linux internals, including kernel subsystems and security frameworks (SELinux, AppArmor, seccomp, etc.)
• Experience with confidential computing and memory encryption technologies (SEV, TDX, SGX)
• Knowledge of hardware security features and their OS integration (TPM, HSM, secure enclaves)
• Experience with formal methods for OS verification
• Kernel development experience or contributions to Linux kernel
• Background in vulnerability research, exploit development, or fuzzing
• Experience with real-time or embedded operating systems
• Knowledge of hardware security features and their OS integration
• Experience with secure boot technologies
• 5+ years of experience in operating systems security or kernel development
• We encourage you to apply even if you do not believe you meet every single qualification. Not all strong candidates will meet every single qualification as listed. Research shows that people who identify as being from underrepresented groups are more prone to experiencing imposter syndrome and doubting the strength of their candidacy, so we urge you not to exclude yourself prematurely and to submit an application if you're interested in this work
