How to Apply for Platform Security Engineer, Operating Systems

at Anthropic

🏢 About Anthropic

Anthropic is a frontier AI research and product company focused on AI alignment, policy, and security, with a mission to build reliable, interpretable, and steerable AI systems. Unlike generic tech companies, Anthropic specifically emphasizes reducing potential harms from advanced AI through technical safety research, making it unique for engineers who want their security work to have direct impact on AI safety. The company's public stance on ethical considerations in AI development (referenced in their 80,000 Hours career review) suggests they value thoughtful, mission-aligned candidates.

About This Role

This Platform Security Engineer role focuses on hardening operating systems specifically for AI workloads across diverse hardware, requiring deep kernel-level work to minimize attack surfaces in research and production environments. The position is impactful because securing the foundational OS layer directly protects Anthropic's AI models, research, and services from sophisticated threats. You'll be building security infrastructure that enables safe AI development while balancing usability for researchers.

💡 A Day in the Life

A typical day might involve developing SELinux policies for new AI research containers, reviewing kernel configurations for upcoming hardware deployments, and collaborating with AI researchers to understand their security-vs-usability needs. You'd likely spend time writing C code for security modules, analyzing eBPF programs for monitoring AI workloads, and designing OS security architectures that scale across Anthropic's diverse infrastructure.

🎯 Who Anthropic Is Looking For

  • Has 5+ years specifically in Linux kernel security or development, not just general cybersecurity experience
  • Can demonstrate hands-on experience with SELinux/AppArmor policy development and custom Linux Security Modules
  • Has practical eBPF experience for security monitoring in production environments, not just theoretical knowledge
  • Understands how to balance security hardening with usability for AI researchers and data scientists

📝 Tips for Applying to Anthropic

1

Highlight specific examples of OS hardening you've done for specialized workloads (not just general server hardening)

2

Demonstrate understanding of AI infrastructure security challenges (model protection, GPU security, research environment isolation)

3

Show experience with diverse hardware platforms beyond x86 (ARM, specialized AI accelerators) if applicable

4

Reference Anthropic's public AI safety research in your application to show mission alignment

5

Include concrete metrics from past projects (attack surface reduction percentages, performance impact measurements)

✉️ What to Emphasize in Your Cover Letter

['Explain why securing AI infrastructure specifically interests you, not just general platform security', 'Describe a specific OS hardening project where you balanced security with usability requirements', "Connect your experience with Anthropic's focus on AI safety and alignment", 'Mention any experience with research environment security or protecting intellectual property in AI contexts']
