Job Summary

We are looking for an experienced Linux Device Driver Development Engineer with strong expertise in embedded systems, Linux kernel internals, and hardware-software integration. The candidate will be responsible for developing, customizing, debugging, and maintaining Linux platform software and device drivers for custom hardware based on embedded SoCs. This role requires hands-on board bring-up, low-level debugging, and close collaboration with hardware, systems, and application teams in a fast-paced environment.

Key Responsibilities

• Design, develop, customize, and maintain Linux device drivers and platform software for embedded SoCbased systems.
• Work on BSP and platform software development for custom hardware platforms.
• Perform board bring-up activities, including bootloader configuration and early kernel initialization.
• Develop and validate Bare-Metal and Linux drivers, performing hardware-software validation using lab equipment such as oscilloscopes, logic analyzers, and JTAG-based debuggers.
• Drive bootloader development/customization (U-Boot or equivalent), including power-on boot sequence and low-level initialization.
• Debug complex system-level issues across bootloader, kernel, drivers, and hardware layers.
• Understand and interpret board schematics, datasheets, and hardware reference manuals to support driver development and integration.
• Work on kernel upgrades, driver porting, upstreaming, and component integration.
• Develop and customize drivers for peripherals such as GPIO, SPI, I2C, UART, Sensors, NAND, NOR, eMMC, DDR, etc.
• Contribute to Linux kernel subsystems, including scheduler, memory management, IPC, DMA, IOMMU, interrupt handling, polling mechanisms, and NAPI.
• Develop and debug Linux platform drivers for components such as PCIe, Ethernet, USB, GPU, Display, and Multimedia subsystems.
• Handle system-level debugging, issue isolation, and root-cause analysis involving kernel crashes, performance bottlenecks, and hardware-related failures.
• Collaborate closely with cross-functional teams to ensure seamless hardwaresoftware integration.
• Produce high-quality, maintainable, and well-documented code following best practices.
