Iot Embedded Developer

1. Roles and Responsibilities

• Hardware & Firmware Development:

  Design, develop, test, and maintain embedded software and firmware using

  C/C++

  for microcontrollers and microprocessors (e.g., STM32, ESP32, PIC, ARM Cortex-M, Raspberry Pi).

• Circuit & Hardware Integration:

  Collaborate with hardware teams to interface sensors (temperature, accelerometer, gas, light), actuators, analog/digital IOs, and power management modules; assist in schematic reviews and PCB debugging.

• IoT Connectivity & Protocols:

  Implement and optimize communication protocols for IoT devices, including

  MQTT, CoAP, HTTP/HTTPS, BLE, Wi-Fi, LoRaWAN, Zigbee, SPI, I2C, UART, and CAN bus

  .

• Edge & Cloud Integration:

  Connect edge IoT devices seamlessly with cloud platforms (AWS IoT Core, Azure IoT Hub, Google Cloud IoT, or custom MQTT brokers); secure telemetry data transmission using TLS/SSL encryption.

• System Testing & Debugging:

  Perform low-level hardware debugging and firmware testing using logic analyzers, oscilloscopes, multimeters, and JTAG/SWD debuggers; troubleshoot signal integrity, memory leaks, and timing constraints.

• Power & Performance Optimization:

  Optimize firmware code and power consumption profiles to ensure ultra-low power states, battery longevity, and efficient execution on resource-constrained embedded systems.

• OTA & Security Implementation:

  Design and maintain Over-The-Air (

  OTA

  ) firmware updates and implement device security standards, including secure boot, cryptographic hardware keys, and hardware root of trust.

• Documentation & Compliance:

  Create comprehensive technical documentation, including system architecture diagrams, API specifications, testing procedures, and support compliance with industry safety and EMC standards.

2. Preferred Candidate Profile

• Education:

• Bachelors or Master’s degree in Electronics & Communication Engineering (ECE), Electrical Engineering (EEE), Embedded Systems, Computer Science, or related technical disciplines.

• Work Experience:

• 2 to 6+ years

  of hands-on experience in embedded firmware design, microcontrollers, and end-to-end IoT product deployment.

• Technical Skills:

• Proficiency in

  Embedded C/C++

  programming and real-time operating systems (

  FreeRTOS

  or Embedded Linux).
• Strong working knowledge of hardware interfaces (SPI, I2C, UART, ADC) and wireless stacks (Wi-Fi, BLE, LoRaWAN, Cellular/NB-IoT).
• Direct experience with cloud IoT platforms (AWS IoT Core, Azure IoT) and data serialization formats (JSON, Protobuf).
• Familiarity with hardware tools (oscilloscope, logic analyzer, solder station) and IDEs (Keil, STM32CubeIDE, ESP-IDF, VS Code).

• Soft Skills:

• Strong analytical and hardware-software co-debugging skills.
• Good communication and collaboration skills to work across cross-functional hardware, cloud, and QA teams.
