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)

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.
