We are looking for a Senior Embedded Engineer with strong hands-on experience in low-level embedded development . The ideal candidate should be proficient in communication protocols such as UART, SPI, I2C, MDIO , and have experience working with Keil IDE , STM32 , ESP32 , and similar microcontrollers. Knowledge of Realtek processors , RTOS , and network protocols like HTTP, TCP/IP, Web Sockets is a strong advantage. Role & responsibilities : Design, develop, and debug firmware for embedded systems using C/C++ . Implement and interface with protocols including UART, SPI, I2C, MDIO, GPIO , etc. Work on ARM Cortex-M microcontrollers (e.g., STM32 , ESP32 ) and Realtek-based processors. Develop and maintain projects using Keil, STM32CubeIDE , or equivalent toolchains. Implement and optimize networking protocols : TCP/IP, HTTP, Web Sockets , and custom lightweight protocols. Work with peripheral drivers and integrate third-party hardware modules. Write clean, efficient, and well-documented code with a focus on resource-constrained environments . Troubleshoot and resolve firmware issues using logic analyzers, oscilloscopes, and debuggers. Collaborate with hardware, QA, and software teams to deliver integrated solutions. Stay up to date with new microcontroller platforms, tools, and best practices in embedded design. Required Skills : Proficiency in embedded C/C++ and real-time debugging techniques. Strong experience with embedded communication protocols: UART, SPI, I2C, MDIO . Solid understanding of RTOS , interrupt handling, and low-power design. Experience with IDEs and toolchains such as Keil , STM32Cube , ESP-IDF , etc. Hands-on experience with networking protocols (HTTP, TCP/IP, UDP, WebSocket). Familiarity with Realtek processors or similar SoCs is a strong plus. Experience with version control (e.g., Git ), and CI/CD pipelines for firmware. Ability to read schematics and work closely with hardware engineers. Nice to Have: Knowledge of OTA (Over-the-Air) update mechanisms. Familiarity with MQTT , CoAP , or other IoT protocols. Experience working in IoT , Industrial Control , or Smart Devices . Exposure to bootloaders , secure firmware , or cryptographic libraries .
