## Description

We are seeking a Senior Firmware Engineer to design, maintain, and validate NVMe SSD firmware protocol stacks and management interfaces. You will develop NVMe, PCIe Gen5, SMBus, and I3C functionality; diagnose protocol issues; and partner with validation teams to deliver reliable, interoperable storage-controller firmware.
Responsibilities:

 * Design and maintain the NVMe protocol stack, including Admin and I/O command processing and Submission/Completion Queue management.
 * Ensure firmware compliance with current NVMe specifications and PCIe Gen5 protocol requirements.
 * Design and implement SMBus and I3C communication protocols for reliable host-controller data exchange.
 * Implement NVMe command parsing, data-transfer mechanisms, completion flows, and multi-namespace support.
 * Implement SMBus/I3C read and write commands, status monitoring, temperature and voltage reporting, and control-command handling.
 * Develop status-code reporting, Asynchronous Event Notification (AEN), error recovery, timeout, abort, and reset flows.
 * Design SMBus/I3C error-detection and retry mechanisms to protect system stability.
 * Validate interoperability with NVMe compliance tools, host platforms, and JEDEC/MIPI SMBus and I3C requirements.
 * Capture and analyze PCIe/NVMe transactions using protocol analyzers, logic analyzers, and firmware logs.
 * Monitor SMBus/I3C transfer timing and error conditions and improve firmware reliability.
 * Collaborate with validation teams on compliance, stress, hot-plug, power-management, error-injection, and multi-protocol concurrency testing.
 * Provide root-cause analysis and implement fixes for protocol issues identified during validation or in customer environments.
