Role Overview
The IIOT / OT Integration Specialist will focus on PLC data acquisition, OT network integration, and SCADA development to support reliable and scalable industrial data systems. This role is less focused on heavy PLC program development and more on connecting, configuring, and troubleshooting PLCs to ensure accurate and stable tag acquisition for SCADA and IIoT platforms.
The position also covers OT hardware troubleshooting and the implementation of new IIoT / IoT devices within the OT network, working closely with automation, maintenance, and digital teams.
Key Responsibilities
- Configure and connect PLCs (Siemens, Allen-Bradley, OMRON) for data
acquisition and integration with SCADA, historians, and IIoT platforms. - Perform online PLC diagnostics to verify tag quality, communication health, and
data availability (no heavy logic development required). - Develop, maintain, and enhance SCADA/HMI applications (e.g., Ignition,
AVEVA/Wonderware, WinCC) focused on visualization, alarms, and data
logging. - Integrate PLC data into OT networks using standard industrial protocols such as OPC UA, Ethernet/IP, Profinet, and Modbus.
- Troubleshoot OT hardware including PLC racks, I/O modules, network switches, gateways, sensors, and field devices.
- Implement, configure, and commission IIoT / IoT devices (gateways, edge
devices, smart sensors) within the OT environment. - Support commissioning, testing, and validation of new OT integrations and data pipelines.
- Coordinate with Automation, Maintenance, and Digital teams to support
continuous improvement initiatives.
Required Qualifications
- Bachelor’s degree in Electrical, Electronics, Mechatronics, Computer
Engineering, or a related discipline. - Solid hands-on experience with PLC connectivity and troubleshooting,
particularly Siemens and Allen-Bradley platforms. - Strong understanding of PLC tag structures, addressing, and communication
setup for data extraction. - Experience working with SCADA systems and OPC-based data integration.
- Practical knowledge of industrial Ethernet and OT networking concepts.
- Ability to troubleshoot both software and hardware issues in live plant
environments. - Preferably with 3-4 years of work experience
- Willing to work in General Trias, Cavite
Preferred/Advantage Skills
- Experience with OT data historians and SQL-based data storage.
- Exposure to IIoT architectures and OT-to-IT data flows.
- Familiarity with industrial gateways, edge computing devices, and protocol
converters. - Basic understanding of OT/ICS cybersecurity best practices.
- Ability to read electrical drawings and network layouts.
