Systems Integrity Security Architect

About Anthropic

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.

We're seeking a Systems Integrity Security Engineer to design and implement security architectures for bare-metal infrastructure. You'll work with teams across Anthropic to build firmware, bootloaders, operating systems, and attestation systems to ensure the integrity of our infrastructure from the ground up.

This role requires expertise in low-level systems security and the ability to architect solutions that balance security requirements with the performance demands of training AI models.

• Design and implement secure boot chains from firmware through OS initialization for diverse hardware platforms (CPUs, BMCs, peripherals, embedded microcontrollers)
• Architect attestation systems that provide cryptographic proof of system state from hardware root of trust through application layer
• Define trust boundaries and security policies for multi-party authorization systems
• Develop measured boot implementations and runtime integrity monitoring
• Create reference architectures and security requirements for bare-metal deployments
• Integrate security controls with infrastructure teams without impacting training performance
• Prototype and validate security mechanisms before production deployment
• Conduct firmware vulnerability assessments and penetration testing
• Build firmware analysis pipelines for continuous security monitoring
• Document security architectures and maintain threat models
• Collaborate with hardware vendors to ensure security capabilities meet our requirements

• 8+ years of experience in systems security, with at least 5 years focused on firmware and hardware security (firmware, bootloaders, and OS-level security)
• Hands‑on experience with secure boot, measured boot, and attestation technologies (TPM, Intel TXT, AMD SEV, ARM Trust Zone)
• Strong understanding of cryptographic protocols and hardware security modules
• Experience with UEFI/BIOS security, boot loader hardening, and chain of trust implementation
• Proficiency in low-level programming (C, Rust, Assembly) and systems programming
• Knowledge of firmware vulnerability assessment and threat modeling
• Track record of designing security architectures for complex, distributed systems
• Experience with supply chain security and firmware vulnerability analysis
• Ability to work effectively across hardware and software boundaries
• Knowledge of NIST firmware security guidelines and hardware security frameworks

• Experience with confidential computing technologies and hardware‑based TEEs
• Knowledge of SLSA framework and software supply chain security standards
• Experience securing large‑scale HPC or cloud infrastructure
• Contributions to open‑source security projects (coreboot, CHIPSEC, etc.)
• Background in formal verification or security proof techniques
• Experience with silicon root of trust implementations
• Experience working with building foundational technical designs, operational leadership, and vendor collaboration
• Previous work with AI/ML infrastructure security

Final date to receive applications: None. Applications will be reviewed on a rolling basis.
