3+ years of experience in SSD controller and firmware development, with strong knowledge of NVMe protocol stack architecture. #2. Strong C/C++ programming and data structures experience in embedded software/firmware development. #3.
Hands-on experience with NVMe command processing, Submission/Completion Queues, PCIe Gen5, and NVMe protocol compliance. #4. Strong experience with SMBus and/or I3C protocols, including command handling, data transfer, error detection, and recovery. #5.
Hands-on experience with firmware debugging and validation using JTAG/ICE debuggers, protocol analyzers, logic analyzers, and firmware logs.
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 SMBus/I3C 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 SMBus/I3C 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 SMBus/I3C 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.
