Must have

• BS or MS in Computer Science, Electrical Engineering, or a related field.
• Proficiency in C and C++ for embedded and system-level development.
• Strong experience with Linux internals (system services, IPC, device drivers, kernel/user space interactions).
• Solid understanding of embedded system architecture, SoC components, and hardware/software interaction.
• Experience with scripting languages (Bash, Python) for build, automation, and testing.
• Familiarity with common hardware interfaces (I2C, SPI, UART, USB, PCIe).

Nice to have

• Experience with Linux kernel configuration, building, and debugging.
• Knowledge of ARM-based platforms and low-level hardware bring-up.
• Exposure to middleware frameworks, IPC mechanisms (DBus, gRPC), or platform APIs.
• Experience with OTA update systems for OS, applications, and firmware.
• Understanding of multimedia pipelines, CUDA/OpenCL, or GPU acceleration.
• Familiarity with CAN/CAN-FD or other automotive/industrial protocols.
• Experience with security frameworks (secure boot, encryption, key management) in embedded systems.
