## About the Role

* 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/OpenEmbedded, 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 SoCs
 * 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

## Description

* 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/OpenEmbedded-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
