Linux Core Storage Development Engineer

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

• 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.
  
  

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 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

• 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.
