• Integrate logging, monitoring, and alerting across cloud infrastructure to validate control effectiveness and detect misconfigurations or threats

• Build and tune cloud-native detections using CloudTrail, GuardDuty, Config, and SIEM integrations

• Support incident response for cloud security events, drive root-cause analysis, and translate findings into improved guardrails and controls

Required Qualifications:

• 6+ years of hands-on experience in cloud security engineering, infrastructure security, DevSecOps, or a closely related security engineering role

• Expert-level proficiency with Terraform, including module design, state management, policy-as-code, and managing complex multi-environment configurations

• Deep expertise in AWS security services and architecture, including IAM, Organizations, SCPs, Control Tower, CloudTrail, Config, GuardDuty, Security Hub, KMS, and VPC security

• Demonstrated experience building security guardrails and reusable infrastructure patterns that engineering teams adopt without friction

• Strong experience with CI/CD pipeline security, IaC review processes, and automated compliance validation

• Experience operating in AWS GovCloud or FedRAMP-regulated cloud environments

• Strong proficiency in Python, Go, Rust, or equivalent languages for building security automation and tooling

• Ability to obtain and maintain a security clearance

Preferred Qualifications:

• Experience in defence, aerospace, robotics, autonomy, or other high-assurance environments

• Experience designing multi-account AWS landing zones and organisational security architectures from the ground up

• Hands-on experience with Kubernetes security, container security, and service mesh security in cloud-native environments

• Familiarity with NIST SP 800-171, NIST SP 800-53, FedRAMP, or Cloud Computing SRG Impact Levels

• Experience with infrastructure drift detection, automated remediation, and continuous compliance monitoring

• Relevant certifications such as AWS Security Specialty, AWS Solutions Architect Professional, HashiCorp Terraform Associate/Engineer, CCSP, or CISSP

Anthropic's mission is to create reliable, interpretable, and steerable AI systems. We want AI to be safe and beneficial for our users and for society as a whole. Our team is a quickly growing group of committed researchers, engineers, policy experts, and business leaders working together to build beneficial AI systems.

About the Team

The Security Engineering team protects Anthropic's AI systems and maintains the trust of our users and society. We define the authentication architecture for our training infrastructure, design the cryptographic foundations that protect model weights and training data, and drive the developer security program that shapes how engineers build and ship software.

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 organisation, 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

Developer security and supply chain

• 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

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 our multi-cloud environments

Infrastructure security

• 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

Secure frameworks

• 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

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 organisational dynamics
• Outstanding communication skills, translating technical concepts effectively across all levels of the organisation
• 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 organisation
• 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, with depth in toolchain issues, CI/CD pipelines, and developer workflow optimisation
• Implemented machine identity or workload authentication systems using SPIFFE/SPIRE, mTLS, or equivalent
• Understanding of Linux systems internals including namespaces, cgroups, and seccomp, and how these underpin container and workload isolation
• 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
