Anthropic is seeking a Security Engineer specializing in offensive security to join its Security Engineering team. The team's mission is to safeguard AI systems and maintain trust with users and society.
In this role, you will conduct red and purple team engagements simulating advanced threat actors across cloud infrastructure, endpoints, and bare metal deployments. You'll perform penetration testing on high-value deployments, contribute to AI-assisted security testing tooling and workflows, and work cross-functionally with security and engineering teams on AI-specific attack scenarios. A key responsibility is documenting and presenting findings to both technical and executive audiences, translating attack narratives into actionable risk insights that inform security roadmaps.
You bring 5+ years of hands-on experience in red teaming and offensive security operations. You have deep expertise in at least two of: macOS security, Linux security, cloud security (GCP/AWS/Azure), Kubernetes, or CI/CD pipelines. You have a proven track record of discovering novel attack vectors and chaining vulnerabilities creatively, with experience conducting adversarial simulations against well-defended environments. Strong engineering skills in Python, Go, or similar languages are essential, along with the ability to write clear findings that drive action and help teams understand risk and prioritize fixes. You work collaboratively with blue teams.
Strong candidates may also have experience with organizations operating under state actor threat models, interest in AI safety and its relationship to security engineering, background testing AI/ML systems or agentic workflows, familiarity with detection engineering and SIEM/EDR platforms, or experience with data center security or hardware-based attacks.
The role is hybrid with an expectation that staff be in office at least 25% of the time, though some roles may require more. Visa sponsorship is available.
