Security Engineer, Offensive Security

Anthropic Anthropic · AI Frontier · San Francisco, CA · Security

This role focuses on offensive security for AI systems, including red teaming, penetration testing, and developing AI-assisted security tooling. While the role supports AI systems, its core craft is security engineering, not direct AI/ML model development.

What you'd actually do

  1. Conduct red and purple team engagements simulating advanced threat actors across our cloud infrastructure, endpoints and bare metal deployments.
  2. Penetration test specific, high value deployments.
  3. Contribute to AI-assisted security testing tooling and workflows.
  4. Work cross functionally with other security and engineering teams, particularly on AI-specific attack scenarios.
  5. Document and present findings to technical and executive audiences, translating attack narratives into actionable risk insights that inform security roadmaps.
