As an Embedded Software Engineer at 3M’s Self-Contained Breathing Apparatus (SCBA)/Fire Solutions R&D Team in Monroe, NC, you will design and maintain embedded firmware for microcontroller-based systems used in portable, rugged electromechanical products. Your daily tasks include developing low-level drivers, communication protocols, real-time control algorithms, and optimizing firmware for performance and reliability. You’ll leverage advanced AI-assisted tools to enhance validation efficiency and troubleshoot system issues using diagnostic equipment. Key skills required are experience with STM32 MCUs, Cesium RTOS, radio technologies like BLE and LoRa, and professional embedded development tools such as IAR Embedded Workbench. Additionally, proficiency in GitHub workflows, DevOps practices for automated builds, static code analysis, and test automation is essential. This role involves collaborating closely with hardware teams to validate board bring-up and peripheral functionality while ensuring high-quality documentation and adherence to coding standards like MISRA guidelines.
