About The Position

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.

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 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

Nice To Haves

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

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
