The Opportunity

We are looking for an experienced Freelance PLC Programmer / Commissioning Engineer to support a major warehouse automation and intralogistics project in Germany.

The project involves highly automated material-handling systems, including conveyors, sortation, AMRs, robotic/cobot applications and warehouse control systems.

This is a hands-on role covering PLC programming, equipment integration, testing, commissioning, troubleshooting and go-live support.

• Develop and modify Siemens PLC software using TIA Portal
• Commission and troubleshoot automated warehouse systems
• Support integration of conveyors, sorters, material-handling equipment and AMRs
• Develop equipment and robot interfaces / handshakes
• Configure and troubleshoot HMI / diagnostics
• Execute FAT, SAT, I/O and functional testing
• Support site startup, production ramp-up and go-live
• Troubleshoot PLC, network, sensor and equipment issues
• Work closely with electrical, mechanical, robotics and WCS teams
• Support customer acceptance and technical handover

What We're Looking For

• Strong S7-1500 experience
• S7-1200 / WinCC experience
• Experience with distributed I/O
• Programming knowledge in ST, LAD and/or FBD
• Strong hands-on commissioning and troubleshooting experience
• Experience with FAT / SAT / site startup
• Ability to work independently on customer sites

Experience in one or more of the following:

• Intralogistics
• Warehouse automation
• Manufacturing logistics

Experience with conveyors, sortation, pallet transport, AS/RS, shuttle systems or material-flow systems is highly relevant.

Nice to Have

• AMR integration — MiR, Geek+, Locus, Omron, ForwardX or similar
• Robotics / cobots
• Siemens Safety PLC
• Beckhoff TwinCAT
• WCS / WMS interfaces
• AS/RS
• Shuttle systems
• AutoStore

AMR experience is highly desirable but not mandatory — strong Siemens PLC + intralogistics + commissioning experience is the priority.

This is a hands-on commissioning role. Regular travel to customer/project sites within Germany is expected, particularly during commissioning and go-live phases.

Right to Work: Candidates must have valid EU/German work authorization and be legally able to undertake freelance work in Germany. Visa sponsorship is not available for this project.

If you are a PLC Programmer, Controls Engineer or Commissioning Engineer with strong intralogistics experience, feel free to reach out directly.
