• Experience with RTOS-based development (FreeRTOS, ThreadX, or similar)
• Hands-on experience with ARM Cortex-M or similar microcontroller platforms
• Strong BLE and low-power embedded design experience
• Familiarity with additional communication protocols: I2C, SPI, UART, USB
• Experience with version control (Git) and static analysis tools
• Comfort operating in a lean engineering environment with close leadership access
Preferred Qualifications
• Direct experience with IEC 62304, ISO 13485, or IEC 60601 in a prior role
