What you will do

• Design, build, and ship OpenBMC firmware for custom AI compute boards from reference-hardware bring-up through production deployment.
• Own Yocto/OpenEmbedded builds, board ports, device trees, U-Boot, and Linux kernel integration for the BMC SoC.
• Develop telemetry, inventory, event logging, fan, thermal, power, and RAS capabilities for ASICs and board components.
• Build Redfish, IPMI, MCTP, PLDM, and SPDM management interfaces, including out-of-band ASIC management.
• Implement firmware updates, secure boot, attestation, kernel drivers, D-Bus services, CI, test automation, and firmware tooling.
• Debug hardware and firmware with schematics, logic analyzers, and JTAG while contributing to board and ASIC design decisions.

Requirements

• 8+ years of BMC firmware and embedded Linux experience, including hands-on OpenBMC work from board bring-up through production.
• Strong C/C++, with solid Python or Bash and deep Linux knowledge across user space, drivers, and kernel internals.
• Proficiency with Yocto/OpenEmbedded, U-Boot, device trees, and BMC SoCs such as ASPEED or Nuvoton.
