- Implement management stack using DMTF/OCP standards (MCTP, PLDM, SPDM, Redfish) and IPMI/KCS for sensors, telemetry, and logging
- Own BMC security posture including secure boot, attestation, authenticated updates, and rollback protection
- Lead threat modeling and secure design reviews; coordinate vulnerability disclosure with vendors and upstream
- Build verification tooling including static analysis, fuzzing, and firmware extraction with CI gating
- Manage hardware/firmware boundary work across I2C, SPI, PCIe, BMC-to-BIOS communications, and thermal/power management
What they're looking for
- OpenBMC/BMC firmware development on x86 and Arm platforms
- C/C++ and Python programming with deep Linux kernel/user-space knowledge
- Yocto/OpenEmbedded build systems
- DMTF standards (MCTP, PLDM, SPDM, Redfish) and IPMI
- Firmware security including secure boot, attestation, and root of trust
- Hardware interfaces: I2C/I3C, SPI, PCIe, SMBus, eSPI/LPC

Likely interview questions
- Walk us through a production OpenBMC deployment you've shipped on x86 or Arm—what were the biggest challenges from bring-up through production, and how did you solve them?
- Describe your experience with DMTF/OCP standards like MCTP, PLDM, SPDM, and Redfish. Which have you implemented hands-on, and what surprised you about them?
