Job Overview:

We are seeking an experienced Embedded Systems Engineer with expertise in IoT solutions and hands-on experience with ESP32 microcontrollers. The ideal candidate will design, develop, and optimize firmware for connected devices, ensuring seamless integration with cloud platforms (AWS IoT, Azure IoT, Google Cloud IoT).

Key Responsibilities:

- Design and develop embedded firmware for IoT devices using ESP32 (ESP-IDF, Arduino, FreeRTOS).
- Implement wireless protocols (Wi-Fi, Bluetooth/BLE, LoRa, MQTT, CoAP) for device connectivity.
- Integrate IoT devices with cloud platforms (AWS IoT Core, Azure IoT Hub, Google Cloud IoT).
- Develop low-power firmware for battery-operated IoT sensors.
- Debug and optimize performance, power consumption, and memory usage.
- Work with sensors, actuators, and peripherals (I2C, SPI, UART, ADC).
- Implement OTA (Over-the-Air) firmware updates.
- Ensure secure communication (TLS/SSL, X.509 certificates, encryption).
- Collaborate with hardware engineers on PCB design and prototyping.
- Document firmware architecture, APIs, and testing procedures.

Requirements:

- Bachelor’s/Master’s in Electronics/Computer Engineering or related field.
