About the role

We are seeking a hands-on PLC Programmer to design, develop, commission and support industrial automation and IoT-enabled monitoring systems. The role combines PLC and HMI programming with field installation, device connectivity, data acquisition, remote monitoring and technical support for mechanical equipment and process systems.

Key responsibilities

• Translate client mechanical, electrical and operational requirements into practical control and automation solutions.

• Design, develop and maintain PLC programs, including control sequences, interlocks, alarms and equipment operating logic.

• Configure and integrate HMI and SCADA interfaces for machine operation, status monitoring, alarm handling and fault diagnosis.

• Integrate sensors, actuators, variable-frequency drives, relays, meters, gateways and other field devices with PLC-based systems.

• Connect PLCs and machines to IoT platforms for equipment data collection, remote monitoring, alerts and performance reporting.

• Configure and troubleshoot industrial communication protocols such as Modbus RTU/TCP, OPC UA, MQTT, Ethernet/IP or equivalent protocols used by the project.

• Set up device tags, gateways, dashboards and alert rules, and verify the accuracy and reliability of transmitted data.

• Conduct factory and site testing, installation, commissioning and performance validation before client handover.

• Troubleshoot PLC logic, HMI/SCADA, sensors, control panels, industrial networks, IoT gateways and cloud communication issues.

• Apply basic cybersecurity practices, maintain program backups and technical records, and provide on-site or remote after-sales support when required.

About you

• Diploma in Electrical Engineering, Electronics, Automation, Mechatronics or a related field; equivalent technical certification or relevant hands-on experience will also be considered.

• At least 1 to 2 years of practical experience in PLC programming, machine automation, control systems or industrial commissioning.

• Working knowledge of at least one common PLC platform, such as Siemens, Mitsubishi, Omron, Schneider Electric, Allen-Bradley, Delta or an equivalent system.

• Ability to read electrical drawings, understand I/O wiring and troubleshoot control panels, sensors and field devices.

• Practical understanding of HMI/SCADA, industrial networking and communication protocols such as Modbus, OPC UA and MQTT.

• Basic knowledge of IoT architecture, including sensors, edge devices or gateways, data transmission, dashboards and remote monitoring.

• Able to work independently, diagnose problems systematically and travel to client sites for installation, commissioning and support.

• Exposure to cloud or IoT platforms such as AWS IoT, Microsoft Azure IoT, ThingsBoard or equivalent solutions.

• Experience with REST APIs, SQL or time-series data, Node-RED, Python or other tools used for equipment-data integration.

• Experience in remote diagnostics, dashboard configuration, data logging, alarm notification or predictive-maintenance applications.
