Platform Security Engineering (OpenBMC)

Join Anthropic, a leading AI safety and research company, as a Platform Security Engineer. You will be part of a founding team responsible for developing and securing OpenBMC-based management firmware for our server fleet. Your work will involve designing, building, and shipping firmware, implementing communication protocols, and ensuring the security of the BMC. You will also lead threat modeling and secure design reviews, build verification tooling, and collaborate with internal teams and external vendors.

• Design, build, and ship OpenBMC firmware and manageability features for x86 and Arm platforms, from bring-up through production.
• Implement BMC-to-BIOS/host communications, eSPI/LPC, thermal/fan/power management (PMBus).
• Lead threat modeling and secure design reviews; run coordinated vulnerability disclosure with vendors and the upstream community.
• Strong debugging and a track record of shipping reliable, well-tested code
• Working knowledge of out-of-band and in-band management, the relevant DMTF specs, and the device interfaces they run over
• Clear communication across internal teams and external vendors
• Hands-on OpenBMC/BMC firmware experience on x86 and/or Arm, from bring-up through production with hands-on D-Bus/sdbusplus
• Knowledge of NIST firmware security guidelines and hardware security frameworks, specifically SP 800-193 and 800-147/155
• Upstream contributions to OpenBMC, U-Boot, DMTF, or OCP
• Ability to work effectively across hardware and software boundaries
• A security mindset applied to firmware, not bolted on afterward
• 8+ years of experience in systems security, with at least 5 years focused on firmware and hardware security (firmware, bootloaders, and OS-level security)
• Strong C/C++ and Python, deep Linux user-space/kernel fundamentals, and Yocto/OpenEmbedded proficiency
• Strong technical cross-functional leadership skills, direction setting
• Hardware roots of trust and attestation: Caliptra, OCP S.A.F.E., TPM/HRoT, SPDM
• Memory-safe systems code in Rust or Zig
• Firmware vulnerability research, reverse-engineering, or fuzzing
• Previous work with AI/ML infrastructure security
• Required field of study: A field relevant to the role as demonstrated through coursework, training, or professional experience
• Minimum education: Bachelor’s degree or an equivalent combination of education, training, and/or experience
• We encourage you to apply even if you do not believe you meet every single qualification. Not all strong candidates will meet every single qualification as listed. Research shows that people who identify as being from underrepresented groups are more prone to experiencing imposter syndrome and doubting the strength of their candidacy, so we urge you not to exclude yourself prematurely and to submit an application if you're interested in this work
