BMC Firmware Engineer
MatXJob Title
BMC Firmware Engineer
Role Summary
Design, implement, and ship OpenBMC-based BMC firmware for MatX compute boards. Own BMC bring-up, platform manageability, firmware update and security flows, and the tooling that ensures production readiness for datacenter deployment. Collaborate closely with hardware, silicon, and security engineers.
Experience Level
Senior — 8+ years of BMC firmware and embedded Linux development experience.
Responsibilities
Primary responsibilities include development, integration, and validation of BMC firmware and related platform software:
- Design and implement OpenBMC firmware, Yocto/OpenEmbedded build, U-Boot, and device trees for the BMC SoC.
- Bring up BMC on new boards and support production deployment from initial bring-up through datacenter volumes.
- Develop telemetry, sensor infrastructure, inventory, event logging, and RAS features for board components and ASICs.
- Build and maintain management interfaces and protocols: Redfish, IPMI, MCTP, PLDM, SPDM, and out-of-band ASIC management.
- Implement firmware update, secure boot, and attestation flows in partnership with silicon and security teams.
- Write and debug Linux kernel drivers and D-Bus/sdbusplus services; debug across hardware/firmware boundary using schematics, logic analyzers, and JTAG.
- Review schematics and hardware architecture for manageability and debuggability; influence board and ASIC design decisions.
- Contribute upstream improvements to OpenBMC where appropriate and build CI, test automation, and firmware tooling.
Requirements
Must-have technical skills and experience:
- 8+ years of BMC firmware and embedded Linux development, with board bring-up through production.
- Strong C/C++ and experience with Python or Bash; deep Linux user-space and kernel fundamentals.
- Proficient with Yocto/OpenEmbedded, U-Boot, and device trees; experience with BMC SoCs such as ASPEED or Nuvoton.
- Hands-on experience with low-level buses and interfaces: I2C/I3C, SPI, eSPI/LPC, SMBus, UART, PCIe, and JTAG.
- Familiarity with platform management standards: IPMI/KCS, Redfish, and DMTF protocols (MCTP, PLDM, SPDM).
- Ability to operate autonomously on a small team and collaborate closely with hardware, silicon, security, and systems engineers.
- Strong technical communication and documentation skills.
- Nice-to-have: firmware update/security experience, contributions to OpenBMC or the Linux kernel, pre-silicon validation or FPGA prototyping, SR-IOV/VFIO familiarity, kernel profiling experience, or Rust for systems programming.
Education Requirements
