About the Team
The Security Engineering team protects Anthropic's AI systems and maintains trust. Areas include identity and secrets management, developer security and supply chain, infrastructure security, and secure frameworks. You will own one or two areas and contribute to others.
About the Role
- 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
- Enable other teams to build their own security solutions by providing design pattern guidance and expanding security ownership
Developer security and supply chain
- Build and advance developer security program by embedding security practices into SDLC and developer workflows
- Harden CI/CD pipelines against supply chain attacks through isolated build environments, signed attestations, dependency verification, and automated policy enforcement
Identity and secrets management
- Architect systems that protect sensitive assets including model weights, customer data, and training datasets
- Build and operate credential issuance, rotation, and workload authentication across multi-cloud environments
Infrastructure security
- Implement and maintain cloud security controls including IAM, network segmentation, VPC architecture, and encryption across 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
Secure frameworks
- Build critical security foundations including cryptographic frameworks, mTLS infrastructure, secure serialization, and authorization systems
- Partner with product, research, infrastructure, and other security teams to ensure frameworks integrate smoothly
You may be a good fit if you have:
- 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
Strong candidates may also have:
- Designed or operated identity and secrets management systems for large-scale AI or cloud infrastructure
- Built security frameworks or libraries adopted across an engineering organization
- Led a developer security program including supply chain security, secure build infrastructure, and SDLC integrations
- Built or secured CI infrastructure using Nix, Bazel, or Kubernetes-based deploy systems
- Implemented machine identity or workload authentication systems using SPIFFE/SPIRE, mTLS, or equivalent
- Understanding of Linux systems internals including namespaces, cgroups, and seccomp
- Contributed to the security architecture of multi-cloud environments including network segmentation, data protection, and access governance
- Experience with network security controls including admission controllers, CNI-level policy, service mesh security, and east-west traffic enforcement
- Experience building runtime security monitoring using eBPF or kernel security policies
