Develop and optimize CAN / CAN FD, OBD-II, and UDS communication stacks for vehicle data collection. Implement real-time data acquisition, logging, and edge analytics for on-vehicle insights. Work on wireless connectivity (4G/LTE, WiFi, BLE, GNSS) and secure cloud data transmission. Design and maintain bootloaders, OTA (Over-the-Air) update mechanisms, and secure firmware upgrade systems. Develop firmware-level database integration for logging and synchronizing data with backend systems (e.g., embedded database, flash-based logs, or direct API sync with cloud databases). Implement data buffering, compression, and fail-safe log storage to handle offline or low-connectivity scenarios. Collaborate with backend engineers to define data schemas, synchronization logic, and retention strategies. Work with hardware teams for board bring-up, validation, and peripheral driver development (UART, SPI, I2C, SDIO). Ensure compliance with automotive communication and safety standards. Lead debugging, validation, and testing efforts to ensure firmware reliability and field performance. Mentor junior engineers and maintain comprehensive technical documentation.
