NPU MI (Management Interface) Software Engineer
RESPONSIBILITIES
- Design and develop the NPU Management Interface (MI) firmware/software enabling communication between Host/BMC and NPU devices
- Implement and maintain MCTP, PLDM, and custom MI command handling for out-of-band NPU management, monitoring, and control
- Develop device-management features over SMBus/I²C, I3C, PCIe VDM, or custom sideband channels
- Integrate MI functionality into the NPU firmware, including:
- Health and error reporting
- Thermal and power telemetry
- Runtime status, utilization metrics, and debug information
- Ensure compliance with industry specifications by performing spec-driven design, implementation, and validation
- Support bring-up, interoperability testing, rack-scale platform integration, and system-level validation
- Develop test strategies and validation tools based on MCTP and PLDM specifications
- Perform protocol compliance testing, regression testing, and interoperability verification
REQUIREMENTS
- Strong proficiency in embedded C or C++
- Experience with firmware development for NPU/accelerator, GPU, or SoC
- Understanding of management protocols including MCTP (over I²C/SMBus, I3C or PCIe VDM) and PLDM
- Experience with low-level interfaces: SMBus/I²C, I3C, SPI, PCIe
- Ability to interpret complex protocol specifications and convert them into robust implementations
- Familiarity with device telemetry, sensor frameworks, watchdog/reset flows, and health monitoring
- Experience with system-level debugging using logic/protocol analyzers and low-level debug tools
- Knowledge of embedded systems, bare-metal or RTOS environments, and firmware lifecycle flows
PREFERRED QUALIFICATIONS
- Experience of BMC firmware stacks such as OpenBMC, Redfish, IPMI, and PLDM device-model implementations
- Background in spec creation, requirement definition, or standards compliance validation
- Experience defining FRU data, power/thermal management policies, and diagnostic...
