BMC Firmware Engineer

BMC Firmware Engineer

Mountain View, CA

MatX's mission is to make the world's best AI models run as efficiently as allowed by physics, bringing the world years ahead in AI quality and availability. MatX is seeking System Software Engineer to join our team as we create best-in-class silicon for high-performance and sustainable GenAI. Successful candidates for these roles will be responsible for delivering performant and functionally accurate silicon for MatX products across compute, memory management.

High-speed connectivity and other key technologies.

• Design, build, and ship OpenBMC firmware for our custom compute boards, where the BMC manages our in-house AI ASICs — from early bring-up on reference hardware through production deployment
• Own the Yocto/Open Embedded-based build, board port, and device trees (U-Boot and Linux kernel) for our BMC SoC
• Develop platform manageability features: sensor and telemetry infrastructure, inventory, event logging, fan/thermal/power management (PMBus), and RAS for the AI ASICs and board components (CPLDs/FPGAs, PSUs, NICs, memory)
• Build management interfaces on industry standards — Redfish, IPMI, and DMTF protocols (MCTP, PLDM, SPDM) — including out-of-band management of our ASICs
• Implement firmware update, secure boot, and attestation flows in partnership with our silicon and security teams
• Write and bring up Linux kernel drivers and D-Bus/sdbusplus services; debug across the hardware/firmware boundary with schematics, logic analyzers, and JTAG
• Influence board and ASIC design: review schematics and hardware architecture from a manageability and debuggability perspective
• Upstream improvements to the OpenBMC community where appropriate, and build the CI, test automation, and tooling that keep our firmware quality high

• 8+ years of experience in BMC firmware and embedded Linux development, with hands-on OpenBMC experience from board bring-up through production
• Strong C/C++ and solid Python or Bash; deep Linux fundamentals spanning user space, the driver model, and kernel internals
• Proficient with Yocto/Open Embedded, U-Boot, and device trees; experience with BMC SoCs such as ASPEED or Nuvoton
• Board bring-up experience with low-level buses and interfaces: I2C/I3C, SPI, eSPI/LPC, SMBus, UART, PCIe, JTAG
• Working knowledge of platform management standards: IPMI/KCS, Redfish, and DMTF protocols (MCTP, PLDM, SPDM)
• Experience with thermal/power management, firmware update mechanisms, and firmware security (secure boot, root of trust, attestation) is a strong plus
• Contributions to OpenBMC, the Linux kernel, or related open-source/OCP/DMTF efforts are a plus
• Comfortable operating with high autonomy on a small team, collaborating closely with hardware, silicon, security, and systems engineers
• Excellent technical communication and documentation skills

• Experience with pre-silicon validation environments (simulation, emulation, FPGA prototyping)
• First-silicon or new-platform bring-up experience for accelerators, NICs, or So Cs
• Familiarity with SR-IOV, dma-buf, peer-to-peer PCIe, or VFIO
• Kernel performance tuning and profiling experience (perf, ftrace, eBPF)
• Exposure to BMC/host interaction paths (e.g., in-band vs. out-of-band device access, sideband interfaces such as I2C/SMBus)
• Rust for systems programming
