Platform Security Engineering, Auditor

About the role

We're seeking a vulnerability assessment candidate for platform security. You'll work cross-functionally with teams across Anthropic and our partners to assess security features in hardware, firmware, bootloaders, operating systems, and attestation systems to identify and remove vulnerabilities from the ground up.

This role requires expertise in low-level systems security and the ability to audit the most security-critical platform elements. You will take ownership of eliminating identified vulnerabilities in production, ensuring known issues are not reintroduced.

Key Responsibilities

• Audit secure boot chains from firmware through OS initialization for diverse hardware platforms (CPUs, BMCs, switches, peripherals, and embedded microcontrollers)
• Audit attestation systems providing cryptographic proof of system state from hardware root of trust through the application layer
• Audit measured boot implementations and runtime integrity monitoring
• Integrate security controls with infrastructure teams without impacting performance
• Validate security mechanisms before production deployment
• Conduct firmware vulnerability assessments and penetration testing
• Build firmware vulnerability assessment 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 for exploit mitigation

Minimum Qualifications

• Proven track record of conducting hands-on vulnerability auditing on complex, security-critical systems
• 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 languages (C, Assembly) and systems programming
• Knowledge of firmware vulnerability assessment and threat modeling
• Ability to work effectively across hardware and software boundaries
• Strong communication and cross-functional collaboration skills
• Track record of assessing security architectures for complex, distributed systems

Preferred Qualifications

• 8+ years of experience in systems security, with at least 5 years focused on low-level security (firmware, bootloaders, and OS kernel-level security)
• Capacity to audit for logic bugs in code written in Rust or Go
• Ability to find vulnerabilities via reverse engineering in software provided only in binary form
• Experience performing fault injection & side-channel analysis attacks on hardware
• Experience auditing silicon root of trust implementations
• Experience auditing confidential computing technologies and hardware-based TEEs
• Background in formal verification or security proof techniques
• 5 or more talks at top-tier security conferences with candidate listed as first author
• Experience using LLMs to automate security assessment (including tooling creation)
• Experience securing large-scale HPC or cloud infrastructure
• Previous work with AI/ML infrastructure security

Logistics

• Annual Salary: $320,000-$405,000 USD
• Minimum education: Bachelor’s degree or an equivalent combination of education, training, and/or experience
• Required field of study: A field relevant to the role as demonstrated through coursework, training, or professional experience
• Minimum years of experience: Correlates with internal job level requirements
• Location-based hybrid policy: Staff expected to be in one of our offices at least 25% of the time
• Visa sponsorship: Available, with efforts made to secure visas for successful candidates
