Job Description

Job Summary:

We are seeking a skilled Staff SSD Firmware Engineer to focus on infrastructure-level firmware development for Solid-State Drives (SSDs). This role involves expertise in power management , device initialization , and inter-processor communication (IPC) to ensure efficient and reliable SSD operation. You will work closely with ASIC, hardware, firmware, and validation teams to develop and optimize critical SSD functions, including boot-up, power management, system initialization, and inter-processor communication.

Key Responsibilities:

• Power Management & Optimization :

• Develop firmware for low-power modes (e.g., sleep, standby) and ensure efficient power usage.

• Implement power-loss protection mechanisms for safe shutdown and recovery.

• Initialization Firmware :

• Develop and manage bootloader and initialization processes for SSD controllers, NAND, DRAM, and flash interfaces.

• Implement self-diagnostics during boot to detect and resolve issues early.

• Inter-Processor Communication (IPC) :

• Design IPC mechanisms for efficient synchronization and data exchange between processors within SSD architecture.

• Ensure error handling and recovery for complex operations like wear leveling and garbage collection.

• Firmware Development for Embedded Systems :

• Write low-level, bare-metal firmware for embedded SSD subsystems and maintain low-level drivers and hardware abstraction layers.

• Debugging & Optimization :

• Use debugging tools (JTAG, oscilloscopes) to troubleshoot and optimize firmware for performance, power efficiency, and reliability.

• Testing & Validation :

• Develop and execute tests for power management, initialization, and IPC subsystems.

• Perform stress and error recovery testing to validate firmware robustness.

• Collaboration :

• Work with hardware engineers to integrate firmware with hardware components.

• Collaborate with cross-functional teams to ensure seamless SSD system integration.

• Documentation & Reporting :

• Document design, implementation, and testing of infrastructure firmware components, including power, initialization, and IPC.

Qualifications

Required Qualifications:

• Education : Bachelor’s OR master’s degree in computer science, Electrical Engineering, Embedded Systems, or related field.

• Experience :

• 2+ years in embedded systems firmware development, specifically in power management, initialization, and IPC.

• Experience with low-level SSD firmware development, NAND flash, FTL, and interfaces (SATA, NVMe, PCIe).

• Experience in implementing power management algorithms, bootloaders, and IPC for multi-processor systems.

• Skills :

• Proficiency in C/C++ , assembly programming, and embedded system development.

• Familiarity with RTOS and bare-metal development.

• Experience with debugging tools (JTAG, GDB, oscilloscopes).

• Knowledge of hardware interfaces (SATA, NVMe, PCIe) and flash memory management (wear leveling, garbage collection, ECC).

• Problem-Solving : Strong troubleshooting skills, especially in hardware-software integration, power management, and initialization.

• Communication : Excellent written and verbal communication for documentation and cross-team collaboration.

Preferred Qualifications:

• Familiarity with advanced power-loss protection and recovery techniques .

• Knowledge of multicore processing and parallel IPC.

• Experience with performance profiling and optimization in SSD firmware.

• Familiarity with security features like secure boot and encryption.

• Experience with system-level validation of power management and initialization.
