Firmware Engineer

We are looking for a talented Firmware Engineer to develop and maintain embedded software for our solar datalogger/controller. You will implement real-time control, data acquisition, communication protocols, and ensure robust connectivity with IoT cloud platforms.

• Develop firmware for ARM-based microcontrollers and embedded Linux platforms.
• Implement protocols for energy device communication (Modbus RTU/TCP, CAN, MQTT, SNMP).
• Develop drivers for sensors, power meters, relays, and communication modules (WiFi, LTE, RS485).
• Optimize real-time control logic for energy dispatch, storage prioritization, and grid interaction.
• Enable secure data logging, local decision-making, and OTA (Over-The-Air) firmware upgrades.
• Work closely with the hardware and cloud software team to enable seamless end-to-end functionality.
• Ensure stability, memory efficiency, and fault recovery in embedded systems.
• Write and maintain unit tests, debugging logs, and documentation.

• Bachelor’s or Master’s in Embedded Systems, Computer Engineering, or related field.
• 3+ years of experience in embedded C/C++ development.
• Strong understanding of RTOS (FreeRTOS, Zephyr) or embedded Linux.
• Experience interfacing with peripherals (SPI, I2C, UART, GPIO, ADC, PWM).
• Familiar with secure bootloaders, OTA updates, and secure data transmission.
• Knowledge of smart grid and energy dispatch logic is a plus.
• Familiar with CI/CD for firmware, Git, and modern embedded development tools.
