You will be responsible for the entire software lifecycle, from low-level driver development and RTOS configuration to integrating with cloud communication protocols.

Key Responsibilities :

- Design, develop, and test efficient and reliable firmware in C/C++ for embedded systems based on ARM Cortex-M microcontrollers (e.g., STM32, ESP32).

- Deep experience in working with and configuring a Real-Time Operating System (RTOS) such as FreeRTOS or Zephyr.

- Develop and optimize device drivers and hardware abstraction layers (HAL) for peripherals like I2C, SPI, UART, and ADC.

- Implement robust networking and connectivity protocols, including MQTT, CoAP, and TCP/IP stack optimization for low-power operation.

- Ensure code quality and stability through rigorous unit testing, static analysis, and debugging using hardware tools (oscilloscopes, logic analyzers).

- Collaborate with hardware engineers on board bring-up and verification, and with cloud engineers on API integration.

- Manage the build process and version control using Git and CMake/Makefiles.

Technical Skills Required :

- Expert proficiency in C and C++ for bare-metal and RTOS environments.

- Mandatory experience with a commercial or open-source RTOS (FreeRTOS, Zephyr).

- Deep understanding of microcontroller architectures (preferably ARM Cortex-M).

- Hands-on experience with wireless communication standards (Bluetooth LE, Wi-Fi, LoRa).

- Proficiency in debugging tools and techniques for embedded systems.

- Experience with secure boot, secure storage, and device security protocols is a plus
