• Program and configure using Siemens PLC platforms (S7, TIA Portal, WinCC or equivalent)
• Support system integration, testing, and commissioning across a major site's automated handling infrastructure
• Troubleshoot and resolve control system faults during commissioning and post-handover support phases
• Collaborate with mechanical, electrical, and project engineering teams to ensure systems meet performance and safety requirements
• Produce and maintain technical documentation, including control philosophies, I/O lists, and functional specifications
• Support continuous improvement and reliability initiatives as the system transitions into live operation

About You

• Degree qualified in Electrical, Electronic, Mechatronic, or Controls Engineering (or equivalent trade + experience pathway)
• Proven hands-on experience with Siemens PLC programming (S7-300/400/1500, TIA Portal) — essential
• Experience with SCADA/HMI systems (WinCC or similar)
• Background in materials handling, conveyor systems, or large-scale automated logistics systems highly regarded
• Comfortable working on a live, high-profile infrastructure project with strict safety and quality standards
• Strong fault-finding and commissioning experience — able to work through complex control system issues under pressure
• Excellent communication skills, able to liaise across engineering, project management, and client stakeholders

Why Apply

• Be part of the team delivering critical automation systems for a brand-new, large-scale infrastructure project — genuine legacy project experience
• Work with a global benchmark name in automated logistics and materials handling
• Long-term career pathway as the project moves from delivery into ongoing operations and support
• Exposure to large-scale Siemens-based automation systems, sought after across major logistics and infrastructure projects globally
