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.

Minimize attack surfaces by removing as many unnecessary components as possible from kernelspace and userspace

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

Create OS-level attestation and integrity monitoring systems

Apply security patches, develop patches for 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

Serve as a subject matter expert for OS security questions and designs

Minimum qualifications

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
