About the role

Security-focused role building and governing Anthropic's security architecture across identity, secrets, CI/CD, infrastructure, and secure frameworks for AI systems.

Responsibilities

  • Scope, design, and build complex security systems end to end, maintaining them through production and driving through ambiguous technical challenges with minimal oversight
  • Identify systematic risks through threat modeling and risk assessment, then build the controls and infrastructure that address them
  • Mentor engineers across the security team and broader engineering organization, contribute to hiring, and grow security engineering culture at Anthropic
  • Enable other teams to build their own security solutions by providing design pattern guidance and expanding security ownership beyond the security team
  • Build and advance our developer security program by embedding security practices into the software development lifecycle and developer workflows
  • Harden CI/CD pipelines against supply chain attacks through isolated build environments, signed attestations, dependency verification, and automated policy enforcement
  • Architect systems that protect sensitive assets including model weights, customer data, and training datasets
  • Build and operate credential issuance, rotation, and workload authentication across our multi-cloud environments
  • Implement and maintain cloud security controls including IAM, network segmentation, VPC architecture, and encryption across our multi-cloud and on-prem environments
  • Contribute to cluster security controls including RBAC policies, namespace isolation, workload identity, and pod security
  • Contribute to continuous cloud security posture management using infrastructure-as-code scanning, misconfiguration detection, and automated remediation
  • Build critical security foundations including cryptographic frameworks, mTLS infrastructure, secure serialization, and authorization systems, designed to prevent entire classes of vulnerabilities and empower engineering teams to work securely without becoming security experts themselves
  • Partner with product, research, infrastructure, and other security teams to ensure frameworks integrate smoothly with lower-layer security controls

Qualifications

  • At least 8 years of software engineering experience with deep security expertise, including leading complex security initiatives independently
  • Bachelor's degree in Computer Science or equivalent industry experience
  • Strong programming skills in Python or at least one systems language such as Go, Rust, or C/C++
  • Deep understanding of identity systems, cryptographic primitives, and secrets management
  • Working knowledge of Kubernetes security primitives including RBAC, namespaces, network policies, and service accounts
  • Experience leading cross-functional security initiatives and navigating complex organizational dynamics
  • Outstanding communication skills, translating technical concepts effectively across all levels of the organization
  • A track record of bringing clarity and ownership to ambiguous technical problems and driving them to resolution
  • Low ego and high empathy, with a history of growing the engineers around you and supporting diverse, inclusive teams
  • Passion for AI safety and the role security engineering plays in building trustworthy AI systems
