The Senior Service Engineer provides hands-on technical service and lifecycle support for Siemens industrial automation systems at customer sites across the UAE and, when required, the wider GCC, Middle East and EMEA region.

The role focuses on maintenance, troubleshooting, breakdown support, commissioning, modification, upgrades and migration of Siemens PLC, HMI and SCADA systems, particularly in water and wastewater applications & Industry.

The successful candidate must be capable of independently diagnosing complex automation faults in live operating plants, identifying root causes, implementing corrective actions and clearly communicating technical findings.

This is primarily a hands-on Siemens PLC/HMI/SCADA service engineering role. It is not primarily a project management, design engineering, PCS 7, or OT cybersecurity position.

2. Key Responsibilities

The Senior Service Engineer will:

• Perform preventive and corrective maintenance, troubleshooting and breakdown support for Siemens PLC, HMI and SCADA systems.

• Diagnose PLC hardware/software, I/O, HMI/SCADA, industrial communication, instrumentation and electrical/control interface faults.

• Support SIMATIC S7-300, S7-400/400H/400FH, S7-1200, S7-1500 R/H, S7 Safety Systems, STEP 7, TIA Portal, WinCC and Siemens HMI/Comfort Panels.

• Analyze, troubleshoot and modify existing, legacy and unfamiliar PLC/HMI applications.

• Perform approved software modifications, commissioning, recommissioning, functional testing and system recovery.

• Prepare, verify and restore PLC/HMI/SCADA software backups and perform hardware replacement and recommissioning.

• Support lifecycle upgrades and migrations of installed Siemens automation systems.

• Troubleshoot PROFINET, PROFIBUS, Industrial Ethernet, Modbus and related industrial communication interfaces.

• Diagnose interactions between PLC/SCADA systems, field instrumentation, control loops, motors, valves and other control interfaces.

• Investigate recurring failures, identify root causes and recommend corrective or preventive actions.

• Prepare clear technical service reports covering findings, actions, recommendations and outstanding risks.

• Communicate and coordinate effectively with customers, internal engineering teams, OEMs and other stakeholders.

• Work independently during plant breakdowns, shutdowns, outages and other time-critical interventions.

• Follow applicable HSE, cybersecurity, change-control and customer site procedures.
