Platform Security Engineer, DRTM / Secure Launch

About the role

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.

What you’ll do

• DRTM adoption and integration:
• Own adoption and integration of DRTM hardware security features across Anthropic infrastructure, on both x86 and ARM platforms
• Implement attestation services and the additional security and privacy capabilities that DRTM presence enables
• Design and implement a bootloader-agnostic solution for initiating and relaunching DRTM sessions
• Investigate further hardening of existing DRTM solutions: PPAM to isolate SMM on x86, VMM features to isolate UEFI runtime services, ACPI handling and hardening in DRTM environments
• Vendors and upstream:
• Interface with vendor and OEM partners on their DRTM solutions: refine requirements jointly and determine which changes are desirable and feasible
• Publish relevant DRTM work upstream and help carry Linux Secure Launch maintainership as tboot is retired
• Act as technical lead in architecture and design, and disseminate the work through technical papers, conference talks, and community engagement
• Assist other Anthropic teams with their own open source efforts and upstream interactions
• Broader low-level platform work:
• Build and harden other platform security features, including confidential computing solutions such as TDX and SEV
• Support custom operating system artifacts, implement device drivers for custom hardware and features, and do firmware diagnosis and enhancement work
• Debug and diagnose kernel and system-level issues on production hardware
• Take on investigative work in new technical areas and old unsolved ones (for example, the distinct security problems in dTPMs and fTPMs)

What they’re looking for

Select a requirement to inspect fit, evidence or application context.

• Deep hands-on experience with measured boot and roots of trust: DRTM (Intel TXT, AMD SKINIT, ARM equivalents), SRTM, TPM 1.2/2.0, and the measurement chains built on them
• Strong C and assembly, with deep Linux kernel and early-boot fundamentals (bootloaders, UEFI, ACPI, SMM)
• A record of landing non-trivial work upstream in Linux, TianoCore, GRUB, or a comparable community
• Comfort at the hardware/firmware boundary and with the debugging that comes with it: JTAG, serial, platform-level bring-up, silicon errata
• Strong technical cross-functional leadership and direction setting, including with external vendors and OEMs
• Clear written communication: this role produces specifications, design docs, and public technical writing
• Working knowledge of NIST firmware security guidance, particularly SP 800-193 and 800-147/155
• A field relevant to the role as demonstrated through coursework, training, or professional experience

Helpful, not always essential

• 8+ years in systems security, with at least 5 years focused on firmware, bootloader, and OS-level security
• Existing maintainership or subsystem ownership in Linux, or standing in the TCG, UEFI Forum, or OCP communities
• Confidential computing implementation experience: TDX, SEV-SNP, ARM CCA, and their attestation flows
• Hardware roots of trust and attestation beyond the TPM: Caliptra, OCP S.A.F.E., SPDM
• Memory-safe systems code in Rust
• Firmware vulnerability research, reverse engineering, or fuzzing
• Previous work with AI/ML infrastructure security
• The annual compensation range for this role is listed below.
• For sales roles, the range provided is the role’s On Target Earnings ("OTE") range, meaning that the range includes both the sales commissions/sales bonuses target and annual base salary for the role.
• Annual Salary:
• $320,000—$405,000 USD
