Job Summary

Key Responsibilities

• Architect & Lead Storage Subsystem Development:
• Design and implement Linux-based storage stack on embedded/server platforms.
• Define and architect interfaces: eMMC, UFS, NVMe, SATA, SD, USB mass storage.
• Optimize storage stack for performance, power efficiency, and reliability across SoCs.
• Driver Development & Integration:
• Develop and maintain Linux kernel drivers for storage controllers and devices.
• Align with upstream Linux kernel or manage vendor forks.
• Integrate vendor storage IPs and firmware into platform.
• File System & Block Layer Expertise:
• Work with filesystems like ext4, f2fs, xfs, and btrfs.
• Optimize storage performance using I/O schedulers, block layer tuning, and caching.
• Reliability, Data Integrity & Power Resilience:
• Implement features such as journaling, wear leveling, TRIM, and secure erase.
• Ensure data integrity during power loss and work with hardware teams on power sequencing.
• Cross-Functional Collaboration:
• Collaborate with SoC vendors, firmware, hardware, QA, and product management.
• Work closely with bootloader, security, and OTA teams to enable seamless storage integration.
• Debugging & Performance Analysis:
• Use tools like blktrace, fio, perf, strace, iostat, kernel logs for performance profiling and issue debugging.
• Investigate and resolve field issues related to storage corruption or I/O latency.
• Compliance & Validation:
• Validate storage stack against standards (JEDEC, UFS, USB, NVMe, SD).
• Ensure compliance with security frameworks (dm-crypt, LUKS, SELinux/AppArmor, secure boot).
• Mentorship & Technical Leadership:
• Lead a team of kernel and platform engineers.
• Drive code quality through reviews and best practices in Linux kernel/storage development.
