Job description

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.

About the role

We’re seeking a Platform Hardware 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 across our massive fleet.

Key responsibilities

• Design and implement secure boot chains from firmware through OS initialization for diverse hardware platforms (CPUs, BMCs, switches, peripherals, and embedded microcontrollers)
• Architect attestation systems that provide cryptographic proof of system state from hardware root of trust through application layer
• 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 software and hardware vendors to ensure security capabilities meet our requirements
• Hands‑on experience with secure boot, measured boot, and attestation technologies (TPM, Intel TXT, AMD SEV, ARM TrustZone)
• Strong understanding of cryptographic protocols and hardware security modules
• Experience with UEFI/BIOS or embedded firmware security, bootloader 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
• Ability to work effectively across hardware and software boundaries
• Knowledge of NIST firmware security guidelines and hardware security frameworks

Preferred qualifications

• 8+ years of experience in systems security, with at least 5 years focused on firmware and hardware security (firmware, bootloaders, and OS‑level security)
• 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

The annual compensation range for this role is listed below.

Location‑based hybrid policy: Currently, we expect all staff to be in one of our offices at least 25% of the time. However, some roles may require more time in our offices.

Visa sponsorship: We do sponsor visas! However, we aren’t able to successfully sponsor visas for every role and every candidate. But if we make you an offer, we will make every reasonable effort to get you a visa, and we retain an immigration lawyer to help with this.
