How to Apply for Senior Software Security Engineer

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. What makes Anthropic unique is its explicit focus on AI safety as a core company value, working on high-impact problems at the cutting edge of AI development. Candidates might want to work there to contribute directly to shaping the future of safe AI systems in a company that publicly acknowledges the ethical complexities of frontier AI work.

About This Role

This Senior Software Security Engineer role involves building security for large-scale AI clusters at Anthropic, implementing robust cloud security architecture including IAM, network segmentation, and encryption controls. The role is impactful because you'll be securing the infrastructure that powers frontier AI research and products, designing secure-by-design workflows and CI/CD pipelines that directly affect the safety and reliability of Anthropic's AI systems.

💡 A Day in the Life

A typical day might involve designing IAM policies and network segmentation for new AI training clusters, reviewing security controls in Infrastructure-as-Code templates for cloud deployments, and conducting threat modeling sessions for new AI services. You'd likely collaborate with AI researchers to understand their security requirements while implementing secure-by-default workflows, and mentor junior security engineers on best practices for securing complex cloud environments.
