SU - Software Developer – IoT Platform (Industrial Setting with Arduino-based Devices)

Salary range:

• 1700-2200 USD

Job Summary:

We are looking for a skilled Software Developer to design develop and maintain our Industrial IoT (IIoT) platform with a particular focus on supporting Arduino-based edge devices and other microcontroller-driven solutions. You will play a key role in developing both the cloud/backend systems and the embedded applications that power our connected industrial environments. This position is ideal for someone passionate about bridging embedded systems with cloud computing in industrial settings.

Key Responsibilities:

Platform Development and Maintenance

• Design and develop backend software and APIs that support data ingestion device management and analytics for our IIoT platform.
  
• Build and maintain edge-to-cloud communication flows including support for Arduino and other microcontroller devices (e.g. ESP32 STM32).
  
• Create and manage Over-The-Air (OTA) update mechanisms for edge devices.
  

Embedded Software & Device Integration

• Develop deploy and optimize firmware for Arduino-based devices used in industrial applications (sensors actuators gateways).
  
• Interface with industrial sensors and actuators via analog/digital I/O I2C SPI UART and protocols like Modbus or CAN.
  
• Design robust telemetry and remote control workflows using MQTT HTTP or custom protocols from Arduino to cloud.
  

Cloud & Edge Synchronization

• Develop cloud connectors and integrations with platforms like AWS IoT Core Azure IoT Hub or Google Cloud IoT.
  
• Synchronize edge device states commands and alerts to cloud dashboards and data pipelines.
  
• Implement time-series data storage and visualization using tools like InfluxDB Grafana or TimescaleDB.
  

Security and Reliability

• Implement encryption and secure bootloaders for Arduino-based devices (e.g. TLS with WiFi/BLE modules).
  
• Build resilient mechanisms for error recovery watchdog timers and remote debugging.
  

Collaboration and Documentation

• Collaborate with embedded engineers OT specialists and cloud developers for end-to-end IIoT deployment.
  
• Maintain clean documentation for hardware-software interfaces firmware upgrades and integration workflows.
  

Required Qualifications:

• Bachelors degree in Computer Science Electrical Engineering or related field.
  
• 3 years of software development experience including hands-on work with Arduino-based or similar microcontroller platforms.
  
• Proficiency in C/C for embedded development and at least one higher-level language like Python JavaScript or Go.
  
• Familiarity with industrial-grade sensors actuators and protocols (Modbus OPC UA RS485 etc.).
  
• Experience with MQTT CoAP RESTful APIs and message brokers (Kafka RabbitMQ).
  
• Experience integrating with public IoT platforms (AWS Azure GCP).
  

Preferred Qualifications:

• Experience with other MCUs (ESP32 STM32 Particle Raspberry Pi Pico).
  
• Knowledge of low-power sensor networking and battery-operated deployments.
  
• Familiarity with CI/CD pipelines for embedded systems (e.g. PlatformIO GitHub Actions).
  
• Understanding of edge computing frameworks (AWS Greengrass Balena etc.).
  
• Industrial domain experience (manufacturing energy agriculture or logistics).
  

Soft Skills:

• Strong analytical and problem-solving mindset.
  
• Clear and proactive communicator.
  
• Comfortable with rapid prototyping and iterative development.
• Self-driven with a high attention to detail.
