Responsibilities

• Collaborate with stakeholders to define system requirements and deployment scenarios
• Select components: MCUs (STM32, ESP32, Nordic), sensors, PMICs, LoRa modules, passives
• Design schematics and create 2–4 layer PCB layouts with proper RF, power, and signal routing
• Develop low-power systems (deep sleep, wake-up sources, power optimization)
• Manage component sourcing, PCB fabrication, and hardware bring-up
• Write board bring-up code, startup sequences, and MCU initialization
• Implement low-level drivers (I2C, SPI, UART, ADC, PWM, GPIO) and signal processing logic
• Optimize LoRa communication stack for reliability and energy efficiency
• Develop power-aware firmware (sleep modes, wake interrupts, peripheral shutdown)
• Integrate RTOS (FreeRTOS, Zephyr) or write robust bare-metal code for time-critical tasks
• Perform functional and environmental testing (temperature, humidity, etc.)
• Contribute to mechanical design and rapid prototyping (including Arduino-based PoCs)

Must-Have Skills

• PCB design proficiency (Altium Designer or KiCad, 2–4 layers)
• Strong grasp of low-power design, PMIC integration, and power budgeting
• Hands-on experience with LoRa / LoRaWAN and antenna layout best practices
• Embedded C/C++ (peripheral driver development), Python, RTOS familiarity
• Experience with FreeRTOS/Zephyr or writing scalable bare-metal firmware
• Skilled in hardware debugging (oscilloscope, logic analyzer, JTAG/SWD)
• Knowledge of EMC/ESD design and pre-compliance testing
• Experience managing full prototyping cycles, including Arduino or similar platforms

Nice to Have Skills
