In the posting’s own words

The work sits at the lowest layers of the stack: firmware, bootloaders, kernel, and the silicon features underneath them. It is also unusually public. We expect the DRTM work done here to land upstream, and the person in this role will be a visible participant in the Linux and firmware communities rather than a consumer of them.

What it asks for · 7

  • 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

Also a plus

  • 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

What the job covers

  • 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
  • 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
  • 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)
