About Anthropic
Anthropic’s mission is to create reliable, interpretable, and steerable AI systems. We want AI to be safe and beneficial for our users and for society as a whole. Our team is a quickly growing group of committed researchers, engineers, policy experts, and business leaders working together to build beneficial AI systems. About the Role
We're looking for an Operating Systems Security Engineer to harden and secure the OS layer of our infrastructure. You'll be responsible for designing and implementing OS-level security controls, from kernel hardening to runtime protection, ensuring our systems can withstand sophisticated attacks while maintaining the performance required for AI model training. This is a hands‑on role where you'll work with cutting‑edge hardware and implement novel security solutions for environments that don't exist anywhere else in the world. You'll need to balance extreme security requirements with the operational needs of researchers training models at unprecedented scale. What You'll Do:
Design and implement hardened OS configurations for AI workloads across diverse hardware platforms Develop kernel security policies using SELinux, AppArmor, and custom Linux Security Modules and runtime enforcement mechanisms Implement and maintain full‑disk encryption solutions for diverse storage systems Build security infrastructure for AI systems, research environments, and production services Build secure network stacks with appropriate isolation and segmentation Create OS‑level attestation and integrity monitoring systems Develop security patches, custom kernel modules, and kernel hardening configurations Design secure boot processes and trusted execution environments Work with container teams to ensure proper workload isolation at the kernel level Design privilege separation and mandatory access control policies Implement secure update mechanisms for OS components Build tooling for security configuration management and compliance verification Who You Are:
5+ years of experience in operating systems security or kernel development Deep knowledge of Linux internals, including kernel subsystems and security frameworks (SELinux, AppArmor, seccomp, etc.) Experience with kernel hardening techniques and exploit mitigation Strong programming skills in C and systems programming languages Experience with eBPF for security monitoring and enforcement Understanding of virtualization and containerization security Track record of identifying and fixing OS‑level security vulnerabilities Experience with security‑focused Linux distributions Strong candidates may also have:
Kernel development experience or contributions to Linux kernel Experience with real‑time or embedded operating systems Knowledge of hardware security features and their OS integration Experience with confidential computing and memory encryption technologies (SEV, TDX, SGX) Background in vulnerability research, exploit development, or fuzzing Experience with formal methods for OS verification Knowledge of hardware security features and their OS integration (TPM, HSM, secure enclaves) Compensation
Expected base compensation: $300,000 - $405,000 USD. Includes equity, benefits, and may include incentive compensation. Requirements
Education: Bachelor’s degree in a related field or equivalent experience. Location: Hybrid. Staff expected to be in one of our offices at least 25% of the time. Visa sponsorship: We sponsor visas where possible. Application: No deadline; rolling basis. Candidates are encouraged to apply even if they do not meet every qualification. EEO Statement
We do not discriminate on the basis of protected group status under any applicable law.
