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 diagnostics frameworks

• Familiarity with secure provisioning, firmware update mechanisms, and lifecycle state management

• Experience with large-scale datacenter or HPC system integration (rack-level management, telemetry aggregation)

• Contributions to firmware for accelerator, MCTP/PLDM implementations, or open-source system firmware projects
