Platform Hardware Security Engineer

Details

Design and implement security architectures for bare-metal infrastructure. Work with teams across Anthropic to build firmware, bootloaders, operating systems, and attestation systems that ensure infrastructure integrity from the ground up. The role requires expertise in low-level systems security and the ability to balance security requirements with the performance demands of training AI models across a large-scale fleet.

Responsibilities

• Design and implement secure boot chains from firmware through OS initialization for diverse hardware platforms, including CPUs, BMCs, switches, peripherals, and embedded microcontrollers.
• Architect attestation systems that provide cryptographic proof of system state from the hardware root of trust through the 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 requirements.

Requirements

• Hands-on experience with secure boot, measured boot, and attestation technologies, including TPM, Intel TXT, AMD SEV, and 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 with C, Rust, and Assembly, as well as 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.
• Bachelor’s degree or an equivalent combination of education, training, and experience in a field relevant to the role.

Preferred Qualifications

• At least 8 years of experience in systems security, including at least 5 years focused on firmware and hardware security, firmware, bootloaders, and OS-level security.
• Experience with confidential computing technologies and hardware-based trusted execution environments.
• Knowledge of the SLSA framework and software supply chain security standards.
• Experience securing large-scale HPC or cloud infrastructure.
• Contributions to open-source security projects such as coreboot or CHIPSEC.
• Background in formal verification or security proof techniques.
• Experience with silicon root-of-trust implementations.
• Experience building foundational technical designs, providing operational leadership, and collaborating with vendors.
• Previous work with AI/ML infrastructure security.

Compensation

The annual salary range is $320,000–$405,000 USD.

Benefits and Logistics

Anthropic currently expects staff to work from one of its offices at least 25% of the time, although some roles may require more office time. Anthropic sponsors visas for eligible roles and candidates and retains an immigration lawyer to provide support.
