SU - Software Developer (Industrial IoT Platform with Arduino-based devices)

Role Description
This is a full-time remote role for a skilled Software Developer at a growing U.S.-based company. The Software Developer will be responsible for designing, developing, and maintaining 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.


Qualifications

  • Bachelor’s 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.

Responsibilities

Platform Development and Maintenance

  • Design and develop backend software and APIs that support data ingestion, device management, and analytics for our Industrial Internet of Things (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.


​​​​Compensation

$ 1,700 - $ 2,200 per month, paid in USD depending on experience.

Details

  • Independent contractor agreement paid 2x monthly.

  • Client has a desire for long term commitment.
