Responsibilities of the Senior Firmware Engineer(FE): Protocol Stack Design and Maintenance Design and maintain the NVMe protocol stack, including Admin and I/O command processing, and Submission/Completion Queue management. Ensure full compliance with the latest NVMe specifications and PCIe Gen5 protocol requirements. Design and implement SMBus and I3C communication protocols, ensuring reliable and accurate data exchange with the host controller. Command Processing and Flow Control Implement NVMe command parsing, data transfer mechanisms, and completion flows, supporting multi-namespace operations. Implement SMBI3C read/write commands and data flow, including status monitoring, temperature/voltage reporting, and control command handling. Error Reporting and Recovery Implement proper status code reporting, Asynchronous Event Notification (AEN), and error recovery flows to ensure host compatibility. Handle timeout, abort, and reset scenarios to maintain system stability and minimize host impact. Design SMBI3C error detection and retry mechanisms to prevent transmission errors from causing system failures. Compliance and Interoperability Verify compatibility with industry-standard NVMe compliance tools and host platforms. Validate SMBus and I3C communication against

JEDEC/MIPI

specifications to ensure broad interoperability with different host systems and controllers. Debug and Validation Capture and analyze PCIe/NVMe transactions using protocol analyzers, logic analyzers, and firmware logs. Monitor SMBI3C transfers, analyze timing and error conditions, and ensure firmware implementation is stable and reliable. Collaborate with validation teams to execute compliance, stress, and corner-case tests, including hot-plug, power management, error injection, and multi-protocol concurrency tests. Provide root-cause analysis and implement fixes for protocol-related issues found during validation or in customer systems. Requirements of the Senior Firmware Engineer(FE): Master's degree in Electrical Engineering, Computer Engineering, Computer Science, or a related field. At least 3 years of experience in software/firmware applications engineering. At least 3 years of experience with SSD controller/firmware architecture.
