IoT Software Engineer - Modbus/MQTT Protocols

Position Overview

Key Responsibilities

• Develop and deploy IoT-based safety solutions (e.g., gas leak detection, PPE compliance, fall detection, machine monitoring).
• Integrate safety sensors, wearables, and smart devices with gateways and cloud platforms.
• Work on industrial IoT protocols (MQTT, OPC-UA, Modbus, BACnet, LoRaWAN, Zigbee).
• Build real-time monitoring dashboards for safety observations and predictive analytics.
• Implement edge computing solutions for local decision-making and alerts.
• Ensure data security, integrity, and regulatory compliance (Factories Act, OSHA, ISO 45001).
• Collaborate with cross-functional teams for integration with safety management systems (incident reporting, audit trails, compliance software).
• Conduct system testing, debugging, and performance optimization in harsh industrial environments.
  

Required Skills & Qualifications

• Bachelors/Masters degree in Computer Science, Electronics, IoT, or related field.
• 2 to 5 years of hands-on experience in IoT software development.
• Strong programming skills in Python, C/C++, or Java for embedded and application layers.
• Experience with cloud IoT platforms (AWS IoT Core, Azure IoT Hub, Google Cloud IoT).
• Familiarity with industrial IoT protocols (MQTT, OPC-UA, Modbus, LoRaWAN).
• Strong understanding of real-time data processing, APIs, and databases (SQL/NoSQL).
• Experience in data visualization tools (Grafana, Power BI, or custom dashboards).
• Knowledge of cybersecurity best practices for IoT in industrial networks.
  

Preferred Qualifications

• Experience in Industrial IoT (IIoT) or safety-critical systems.
• Exposure to AI/ML models for predictive maintenance or safety risk forecasting.
• Familiarity with edge AI frameworks (TensorFlow Lite, TinyML, Edge Impulse).
• Experience with RTOS (FreeRTOS, Zephyr) for safety wearables or sensors.
• Prior work in safety compliance tools (EHS software, safety audit platforms).
  

Soft Skills

• Strong problem-solving and analytical mindset with safety-first thinking.
• Ability to translate safety requirements into IoT technical solutions.
• Clear communication and ability to work with safety officers, engineers, and managers.
• Proactive in keeping up with emerging IIoT and safety technologies.
