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

• 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)

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.

• 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.

• 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.

• 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

$ 1700 - $ 2200 per month paid in USD depending on experience.

Details

• Independent contractor agreement paid 2x monthly.

• Client has a desire for long term commitment.
