Prioritized Must Have Skills for the Senior Firmware Engineer(FTL):

#1. 3+ years of experience in SSD controller and firmware architecture, including FTL development.

#2. Strong C/C++ programming and data structures experience in software/firmware development.

#3. Hands-on experience with FTL algorithms, including Garbage Collection, Wear Leveling, bad block management, metadata handling, and NAND error management.

#4. Hands-on experience with JTAG/ICE debugging and firmware debugging, validation, and root-cause analysis.

#5. Strong understanding of NAND flash and SSD technologies, including PCIe/NVMe or SATA protocols and power-loss protection/recovery.

Responsibilities of the Senior Firmware Engineer(FTL):

• Design and Maintain FTL Architecture
  • Develop and maintain the Flash Translation Layer (FTL), including I/O flow, Garbage Collection, and Wear Leveling algorithms to ensure data integrity and maximize NAND endurance.
• Block Management and Metadata Handling
  • Implement bad block detection, isolation, and data migration mechanisms to manage block lifecycle.
  • Design robust metadata structures to support fast mapping table reconstruction and system boot.
• Error Handling Mechanisms
  • Prevent and mitigate NAND-related issues such as read disturb, program/erase failures, and retention loss.
  • Implement RAID encode/decode flows to guarantee data reliability.
• Power-Loss Protection
  • Design and implement power-loss protection algorithms to maintain data consistency and metadata integrity during unexpected shutdowns.
  • Verify and optimize power-loss recovery flow to ensure fast and reliable system startup.
• Performance and Resource Optimization
  • Optimize channel/die/plane access scheduling and parallelism to improve throughput and reduce latency.
  • Enhance DRAM/SRAM usage efficiency and reduce Write Amplification for better endurance and performance.
• Debugging and Validation
  • Develop and analyze FTL traces and logs for performance profiling and issue root-cause analysis.
  • Conduct stress testing, mixed workload testing, power-fail tests, and corner-case verification to ensure firmware stability and reliability.
  • Collaborate with Validation, Hardware, and ASIC teams to resolve cross-functional issues and ensure system robustness.
