Security Engineer • Senior

Who you are

You have 5+ years of hands-on experience in red teaming and offensive security operations — you've developed a deep expertise in at least two of macOS security, Linux security, cloud security (GCP/AWS/Azure), Kubernetes, and CI/CD pipelines. Your track record includes discovering novel attack vectors and implementing effective security measures to safeguard systems.

You possess strong communication skills, enabling you to document and present findings to both technical and executive audiences — translating complex attack narratives into actionable risk insights is second nature to you. You thrive in collaborative environments, working cross-functionally with other security and engineering teams, particularly on AI-specific attack scenarios.

What you'll do

In this role, you will conduct red and purple team engagements simulating advanced threat actors across our cloud infrastructure, endpoints, and bare metal deployments. You'll be responsible for penetration testing specific, high-value deployments, contributing to AI-assisted security testing tooling and workflows. Your work will involve documenting and presenting findings to technical and executive audiences, ensuring that security roadmaps are informed by your insights.

You will collaborate closely with other security and engineering teams to enhance security practices and develop critical security infrastructure. Your contributions will help maintain the trust of our users and society at large, as you work to safeguard our AI systems. You will also have the opportunity to mentor junior team members, sharing your knowledge and expertise to foster a culture of security awareness within the organization.

What we offer

At Anthropic, we provide competitive compensation and benefits, including optional equity donation matching, generous vacation and parental leave, and flexible working hours. You'll have the chance to work in a lovely office space in San Francisco, collaborating with a diverse team of researchers, engineers, and policy experts committed to building beneficial AI systems.
