Storage Development Lead

Job Description :

Role & Responsibilities :

1. 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.

2. Driver Development & Integration :

- Ensure upstream alignment with mainline Linux or maintain vendor-specific forks as needed.

- Integrate vendor storage controller IPs and firmware.

3. 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.

4. Reliability, Data Integrity & Power Resilience :

- Ensure data integrity during power loss (power-fail robustness).

- Work with hardware teams on power rail sequencing and power management integration.

5. Cross-Functional Collaboration :

- Collaborate with bootloader, security, and OTA (Over-The-Air) update teams for seamless storage handling.

6. Debugging & Performance Analysis :

- Root cause field issues (e.g., storage corruption, I/O latency) across layers.

7. Compliance & Validation :

- Ensure support for secure boot, encrypted storage (dm-crypt, LUKS), and SELinux/AppArmor policies where needed.

8. Mentorship & Leadership :

- Conduct code reviews and establish best practices for Linux storage development.

Required Expertise :

Kernel Programming :

- Strong knowledge of Linux storage subsystems (block layer, VFS, I/O stack).

- Proficiency in C and kernel debugging techniques.

Storage Protocols & Interfaces :

- Understanding of storage standards (SCSI, AHCI, NVMe spec, JEDEC).

Filesystems :

Performance & Tuning :

Tools :

Security :

Yocto/Build Systems (optional but useful) :
