Location: Bangalore
Experience Level: 2 to 5 Years
Job Type: Full-Time
About the Role
Our client is looking for a proactive Embedded Linux Software Engineer to drive hardware bring-up, BSP customization, and Linux kernel-level development across custom ARM/RISC-V System-on-Module (SOM) platforms. In this mid-level role, you will bridge hardware-software boundaries, optimizing boot performance, device drivers, and system reliability for high-performance edge computing products.
Key Responsibilities

SOM Integration & Board Bring-up: Perform low-level board bring-up, U-Boot customization, and Linux kernel porting for off-the-shelf and custom SOM architectures (e.g., NXP i.MX, NVIDIA Jetson, TI Sitara, STM32MP1).
BSP & Yocto/Buildroot Development: Design, configure, and maintain custom Linux distributions using Yocto Project (recipes, layers, machine configs) or Buildroot.
Driver Development: Write, modify, and debug Linux kernel drivers and device tree sources (DTS) for peripherals such as I2C, SPI, UART, PCIe, CAN, USB, and MIPI-CSI camera interfaces.
System Optimization: Optimize boot times (Fastboot/Quiet Boot), manage memory footprint, and enhance system power management for edge hardware.
Testing & Diagnostics: Utilize logic analyzers, oscilloscopes, and JTAG debuggers alongside Linux tools (GDB, Valgrind, ftrace) for hardware-software integration and debugging.
Cross-Functional Collaboration: Partner directly with hardware engineering and application teams to define system requirements, debug hardware revisions, and deploy over-the-air (OTA) update frameworks (e.g., Mender, RAUC).

Required Qualifications

Experience: 2–5 years of hands-on experience in Embedded Linux software development on ARM-based SOM platforms.
Language Proficiency: Strong proficiency in C and C++ for system-level programming; scripting expertise in Bash or Python.
Build Systems: Hands-on experience developing and troubleshooting Yocto Project (BitBake, layer creation) or Buildroot configurations.
Kernel & Subsystems: Demonstrated experience with Linux kernel driver development, device trees, and U-Boot bootloader customization.
Hardware Interfacing: In-depth understanding of standard hardware protocols (I2C, SPI, UART, PCIe, Ethernet, USB, GPIO).
Tooling: Proficiency with Git, GDB, JTAG, logic analyzers, and serial consoles for low-level debugging.

Nice-to-Have Skills

Familiarity with Secure Boot, TrustZone, and hardware security modules (HSM/TPM) on SOMs.
Experience implementing OTA update mechanisms (RAUC, Mender, SWUpdate).
Hands-on experience with multimedia frameworks (GStreamer, V4L2) or edge AI accelerators (NPU/GPU integration).
Exposure to containerization on embedded devices (Docker, Balena).

What We Offer

Impactful Work: Directly shape the core architecture of next-generation edge products.
Flexible Environment: Hybrid/Remote workplace options with flexible working hours.
Growth & Mentorship: Direct visibility with leadership and technical ownership over complete SOM life cycles.
Competitive Package: Attractive salary, performance bonuses, health insurance, and learning allowances.
