Responsibilities

Troubleshoot, program, and maintain PLCs (Siemens TIA Portal, Allen-Bradley Studio 5000), HMIs, and safety controllers.
Develop, configure, and maintain Ignition SCADA screens, tag structures, alarm pipelines, and system interfaces.
Support and troubleshoot data integration between machine controls and the Manufacturing Execution System (MES).
Diagnose and resolve issues on industrial networks (EtherNet/IP, Profinet, OPC-UA, Modbus, CAN).
Interpret, modify, and update electrical schematics, control loop diagrams, and P&IDs.
Collaborate directly with local and European equipment vendors/OEMs to troubleshoot complex controls issues, manage major repairs, and coordinate field service interventions.
Maintain a flexible schedule to overlap with European time zones and support critical project calls, factory acceptance testing (FAT/SAT), and remote support.
Work closely with Equipment Engineers and Manufacturing Engineers (MEs) on line installations, equipment transfers, commissioning, and engineering changes (ECR/ECN).
Lead continuous improvement projects aimed at cycle-time reduction, automation optimization, line balancing, and overall downtime minimization.
Perform root-cause analysis (RCA, 5 Whys, 8D) on repeat control failures and implement robust corrective actions.
Establish and refine predictive and preventive maintenance protocols targeting machine availability (MTBF, MTTR, OEE).
Document all control updates and hardware modifications according to quality standards (ISO 9001, IATF 16949).
Provide direct technical support during line stoppages and production ramp-ups.
Train and mentor maintenance technicians on PLC diagnostics, Ignition SCADA troubleshooting, and safety system recovery.
Ensure all machine control modifications comply with OSHA, NFPA 70E, and machine safety standards (ISO 13849, EN/ISO 12100).
