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.
