ROLE PURPOSE
We are looking for an experienced PLC Developer with hands-on experience in industrial automation, machine development, and system integration. The role involves developing and commissioning PLC/HMI-based automation systems, integrating motion control, robots, sensors, and industrial communication protocols. The ideal candidate should be comfortable with machine commissioning, troubleshooting, and cross-functional collaboration across mechanical, electrical, software, and IoT teams.
KEY RESPONSIBILITIES
Develop, program, test, and commission PLC-based automation systems using Mitsubishi GX Works and Siemens TIA Portal/Step 7, and design HMI/SCADA applications using Siemens WinCC and Mitsubishi GOT.
Integrate PLCs with servo drives, VFDs, stepper drives and other motion control systems, along with field devices including sensors, actuators, safety devices, barcode/QR scanners, vision systems, RFID and weighing controllers.
Integrate industrial robots with PLC-based automation systems and support I/O mapping, and develop communication interfaces between PLCs and LabVIEW for testing, data acquisition and automation applications.
Configure and troubleshoot industrial communication networks and protocols, and execute machine commissioning, FAT, SAT and on-site troubleshooting.
Prepare electrical control logic documentation, I/O lists, wiring verification and technical reports, and optimize machine cycle time and improve system reliability.
Resolve automation issues for production teams, and ensure accurate PLC/SCADA data availability for reporting and analysis in collaboration with Software Controls and IT/IoT teams.
Support SPM and machine automation development, including electrical panel troubleshooting, and collaborate with mechanical, electrical, software and cross-functional teams during machine development.
MUST-HAVE EXPERIENCE
2-5 years of hands-on experience in PLC programming, industrial automation, and machine development.
B.Tech/B.E. in Electrical, Electronics, or Instrumentation Engineering.
Strong hands-on experience with Mitsubishi GX Works and/or Siemens TIA Portal/Step 7, including HMI/SCADA development (Siemens WinCC or Mitsubishi GOT).
Strong understanding of RS232/RS485, Modbus TCP/RTU, CANopen, and at least one industrial Ethernet protocol such as EtherNet/IP, PROFINET, or CC-Link.
Experience with OPC-UA/Modbus TCP, HMI driver configuration, tag mapping, and communication health monitoring.
Hands-on experience with digital/analog I/O, sensors, encoders, servo drives, VFDs, stepper motors, vision and positioning systems.
Ability to design and troubleshoot end-to-end industrial communication architecture, and experience integrating PLCs with LabVIEW.
Understanding of industrial safety standards and safety PLCs, and ability to read and interpret electrical drawings and control schematics.
Experience with MES/traceability systems; knowledge of SQL database communication is an advantage.
Strong analytical, troubleshooting, communication, and teamwork skills; experience with ABB, FANUC, Yaskawa, KUKA, Universal Robots, or similar industrial robots is an added advantage.
