- Embedded Linux bring-up (Yocto / Buildroot / Debian)

- Device driver development (I2C, SPI, UART, CAN, USB)

- Camera / audio / sensor integration

- 4G / LTE modem integration

- Power optimization for battery devices

- Bootloader and OTA update implementation

- Debugging field failures and production issues

- Interface with hardware and mechanical teams

- Optimize memory, CPU, and power usage

- Production diagnostics and test firmware

- Support manufacturing and deployment

Required Skills

- Strong experience in RTOS firmware development OR Embedded Linux firmware development

- Strong C / C programming

- Embedded debugging using logic analyzer / scope• Experience with ARM Cortex-M / Cortex-A
