• Configure, customize, and integrate the Linux kernel and embedded bootloaders (e.g., U-Boot).
• Maintain and evolve the Yocto-based Linux build system within a CI/CD pipeline.
• Package and deploy software images for diverse embedded hardware platforms.
• Create tailored Linux distributions for specific embedded applications.
• Collaborate across disciplines (firmware, hardware, systems) to ensure seamless system integration and performance.
• Participate in design reviews and contribute to customer-facing technical documentation and proposals.

• Bachelor’s or Master’s degree in Computer Science, Electrical Engineering, Computer Engineering, or related field.
• 0-2 years of professional experience in embedded software development.
• Proficiency in C or C++ for embedded systems.
• Experience developing and debugging software on embedded hardware (e.g., power systems, motors, sensors).
• Understanding of multi-threaded programming and resource-constrained environments.
• Familiarity with version control, issue tracking, and peer review workflows.
• Strong verbal and written communication skills.

• Practical experience with Embedded Linux and the Yocto Project.
• Experience with Xilinx SoCs or other microcontroller-based systems.
• Proficiency with bootloaders, kernel development, and system bring-up.
