Anthropic is seeking a Platform Security Engineer specializing in Operating Systems to harden infrastructure components in San Francisco, New York City, or Seattle. This hands-on role suits systems security professionals looking to build novel defense mechanisms for advanced AI environments.

Role Overview

The Platform Security Engineer focuses on hardening and securing the operating system layer that supports large-scale AI infrastructure. Professionals in this position design and deploy OS-level security controls, ranging from kernel hardening to runtime protection measures. The role requires balancing strict security demands with the high-performance requirements of researchers training complex AI models across diverse hardware platforms.

Key Responsibilities

Design and implement hardened operating system configurations across varied hardware setups.
Minimize attack surfaces by stripping unnecessary components from both kernelspace and userspace.
Create kernel security policies using SELinux, AppArmor, custom Linux Security Modules, and runtime enforcement tools.
Implement and maintain full-disk encryption solutions alongside secure boot processes and trusted execution environments.
Build OS-level attestation and integrity monitoring systems while applying necessary security patches.
Partner with container teams to guarantee robust workload isolation at the kernel level.
Establish mandatory access control policies, privilege separation, and secure update mechanisms for operating system components.
Develop internal tooling dedicated to security configuration management and compliance verification.

Requirements

Deep knowledge of Linux internals, including security frameworks and kernel subsystems like SELinux, AppArmor, and seccomp.
Strong practical programming skills using C and other systems programming languages.
Familiarity with eBPF applications for security enforcement and monitoring.
Solid understanding of virtualization and containerization security principles.
Documented experience identifying and resolving operating system-level security vulnerabilities.
Minimum education of a Bachelor's degree or equivalent in a relevant field of study.

Nice to Have

Five or more years of professional experience in operating systems security or kernel development.
Direct kernel development experience or formal contributions to the Linux kernel.
Prior background working with real-time or embedded operating systems.
Familiarity with hardware security features, hardware-based enclaves, Trusted Platform Modules (TPM), and Hardware Security Modules (HSM).
Experience utilizing secure boot technologies, confidential computing, and memory encryption technologies such as SEV, TDX, and SGX.
Background knowledge in vulnerability research, fuzzing, exploit development, or formal methods for operating system verification.
