Role Overview

  • This is a critical role responsible for connecting all factory machines to a centralized monitoring system.
  • The engineer will determine, design, and implement the best method to extract machine data through industrial protocols or custom sensor retrofits.
  • The role combines industrial automation, IoT, embedded systems, and edge computing for real time monitoring, analytics, and predictive maintenance.

Key Responsibilities

  • Audit all active machines to assess data availability and optimal connectivity approach.
  • Integrate modern machines using industrial communication protocols such as OPC UA, Modbus, Profinet, APIs, and JDF/CIP4 (Heidelberg).
  • Design and implement connectivity solutions for both automated and manual machines.
  • Design sensor based retrofits for machines without controllers or data ports.
  • Implement production counters, current/power sensors, vibration sensors, and optical/proximity sensors to capture machine run status, production count, and basic machine health metrics.
  • Design and develop embedded systems using ESP32, STM32, Raspberry Pi, or industrial MCUs.
  • Develop firmware (C/C++ / MicroPython) for sensor data acquisition and communication.
  • Design PCBs (basic level) and rugged enclosures suitable for industrial environments.
  • Ensure safe power design, isolation, and industrial grade reliability.
  • Set up edge gateways for machine data collection.
  • Implement MQTT based data pipelines from machines to cloud/platform.
  • Integrate REST APIs and other IoT communication protocols.

Required Skills & Qualifications

  • 2–3 years experience in IoT, embedded systems, or industrial automation.
  • Strong knowledge of PLCs and industrial protocols (Modbus, OPC UA, Profinet).
  • Hands on experience with sensors and instrumentation.
  • Experience with microcontrollers (ESP32, STM32) and embedded systems.
  • Experience with MQTT, REST APIs, and edge computing.
  • Understanding of networking fundamentals (Wi Fi, Ethernet).
  • Ability to read electrical schematics and troubleshoot industrial systems.
  • Strong analytical and problem solving skills.
  • Bachelor’s degree in Electronics, Electrical, Mechatronics, or related field.

Preferred (Nice to Have)

  • Experience in printing/packaging machinery (Heidelberg, Prinect, CIP4/JDF).
  • Experience in OEE or machine monitoring systems.
  • Knowledge of RS485/Modbus and power monitoring systems.
  • Experience deploying large numbers of IoT devices in industrial environments.
  • Familiarity with Node RED or Python based IoT workflows.
  • Exposure to AI based CCTV or video analytics systems.
  • Experience with ruggedized industrial hardware design.
