Develop and maintain Buildroot-based embedded Linux systems, low-level Linux drivers and user-space APIs, and real-time firmware for high-rate sensor data. Integrate hardware interfaces (SPI, I2C, UART, Ethernet), GNSS/IMU/wheel encoder/radar sensors and FPGA subsystems. Optimize data acquisition pipelines, DMA-based I/O, networking for high-rate Ethernet streaming, and apply agile practices.
