The opportunity
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.
What you'll do
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
What they're looking for
- + 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
