Linux Core Platform – Storage Development Lead

Job Title: Linux Core Platform – Storage Development Lead

• Location: Hyderabad
• Experience Required: 8 to 10+ Years
• Job Type: Full-Time

Job Summary

We are seeking a highly skilled and experienced Linux Core Platform – Storage Development Lead to architect, design, and lead development of the Linux-based storage stack for embedded and server platforms. You will work on low-level kernel development, optimize storage performance, ensure data integrity and security, and collaborate with cross-functional teams to deliver robust storage solutions across diverse hardware platforms.

Key Responsibilities

1. 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.

2. 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.

3. 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.

4. 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.

5. 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.

6. 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.

7. Compliance & Validation

• Validate storage stack against standards (JEDEC, UFS, USB, NVMe, SD).
• Ensure compliance with security frameworks (dm-crypt, LUKS, SELinux/AppArmor, secure boot).

8. Mentorship & Technical Leadership

• Lead a team of kernel and platform engineers.
• Drive code quality through reviews and best practices in Linux kernel/storage development.

Required Expertise

Linux Kernel & Storage Stack

• Deep understanding of Linux kernel architecture, block layer, VFS, and I/O subsystems.
• Proficiency in C programming and advanced kernel debugging.

Storage Protocols & Interfaces

• Experience with eMMC, UFS, NVMe, SATA, USB mass storage, SPI-NAND/NOR, SDIO.
• Knowledge of SCSI, AHCI, NVMe spec, and JEDEC standards.

Filesystems

• Expertise in ext4, f2fs; familiarity with log-structured and flash-optimized filesystems.

Performance Tuning

• Deep understanding of I/O performance optimization and flash storage characteristics (latency, endurance, etc.).

Debugging & Tools

• Hands-on with tools: blktrace, fio, iostat, perf, crash, gdb, etc.

Security & Integrity

• Knowledge of secure storage: dm-crypt, dm-verity, rollback protection, key management.

Build Systems (Preferred)

• Experience with embedded Linux build systems (Yocto, Buildroot) is a plus.

Ideal Candidate

• 8–10+ years of relevant experience in Linux kernel and storage development.
• Strong technical leadership and mentoring capabilities.
• Experience working with cross-functional teams on SoC/platform-level integration.
• Proven track record of delivering production-grade Linux storage solutions.
