Firmware Engineer

Overview We are looking for an Embedded Firmware Engineer to join an R&D team developing firmware for advanced optical and high-speed hardware products. You will work closely with hardware and system engineers on MCU-based control, hardware interfaces, device monitoring and product bring-up. Responsibilities • Design, develop, debug and maintain embedded firmware for optical modules and related hardware platforms. • Develop MCU based control and monitoring functions for sensors, power devices and other hardware components. • Implement and debug communication interfaces including I2C, SPI, UART, MDIO and GPIO. • Develop device initialization, configuration, monitoring, fault detection and protection functions. • Support hardware bring-up, system debugging, failure analysis and production introduction. • Develop interfaces between firmware, host software and automated test systems. • Maintain firmware architecture, technical documentation and version control. Requirements • Bachelor's degree or above in Electronics, Computer Engineering, Communications, Automation, Microelectronics or a related discipline. • At least 3 years of embedded firmware or related hardware product development experience. • Strong programming skills in C/C++ with hands-on MCU firmware development experience. • Experience with ARM-based MCU/processor platforms and bare-metal or RTOS development. • Strong knowledge of hardware interfaces such as I2C, SPI, UART, MDIO and GPIO. • Hands-on debugging experience using oscilloscopes, logic analyzers or similar tools. • Experience with Git and embedded development tools such as Keil, IAR, GCC or CMake. • Experience in optical modules, optical communication or high-speed hardware products is highly advantageous. • Python or scripting experience for test automation or firmware debugging is a plus.
