Platform – Storage Development Lead

• Architect & Lead Storage Subsystem Development:

• Design and lead implementation of Linux-based storage stack for embedded or server platforms.
• Define architecture for storage interfaces (eMMC, UFS, NVMe, SATA, SD, USB mass storage, etc.).
• Optimize for performance, power, and reliability on target SoC or platform.
• Driver Development & Integration:

• Develop and maintain Linux kernel drivers for storage devices and controllers.
• Ensure upstream alignment with mainline Linux or maintain vendor-specific forks as needed.
• Integrate vendor storage controller IPs and firmware.
• File System & Block Layer Expertise:

• Work with Linux file systems (ext4, f2fs, xfs, btrfs).
• Optimize storage stack performance using IO schedulers, caching strategies, and tuning.
• Reliability, Data Integrity & Power Resilience:

• Implement support for journaling, wear leveling (especially for flash), secure erase, and TRIM.
• Ensure data integrity during power loss (power-fail robustness).
• Work with hardware teams on power rail sequencing and power management integration.
• Cross-Functional Collaboration:

• Coordinate with SoC vendors, QA, product management, and firmware/hardware teams.
• Collaborate with bootloader, security, and OTA (Over-The-Air) update teams for seamless storage handling.
• Debugging & Performance Analysis:

• Use tools like blktrace, iostat, fio, perf, strace, and kernel logs for performance and issue analysis.
• Root cause field issues (e.g., storage corruption, I/O latency) across layers.
• Compliance & Validation:

• Validate storage against JEDEC/UFS/SD/USB/NVMe standards.
• Ensure support for secure boot, encrypted storage (dm-crypt, LUKS), and SELinux/AppArmor policies where needed.
• Mentorship & Leadership:

• Lead and mentor a team of kernel and platform developers.
• Conduct code reviews and establish best practices for Linux storage development.

• Kernel Programming:

• Strong knowledge of Linux storage subsystems (block layer, VFS, I/O stack).
• Proficiency in C and kernel debugging techniques.
• Storage Protocols & Interfaces:

• Hands-on with eMMC, UFS, NVMe, USB mass storage, SATA, SPI-NAND/NOR, SDIO, etc.
• Understanding of storage standards (SCSI, AHCI, NVMe spec, JEDEC).
• Filesystems:

• Deep knowledge of ext4, f2fs, and familiarity with log-structured or flash-optimized file systems.
• Performance & Tuning:

• Expertise in tuning I/O performance and handling flash-specific issues (latency, endurance, etc.).
• Tools:

• blktrace, iostat, fio, perf, gdb, crash, etc.
• Security:

• Secure storage handling, key management, dm-verity/dm-crypt, rollback protection.
• Yocto/Build Systems (optional but useful):
