PLC - Python - Robotics

I am looking for an experienced software developer to help me with a project that requires programming knowledge of PLC and Python. The project will require working with existing code and the programmer should be comfortable with that. In addition to PLC and Python, no other programming languages are required for this project. Experience with robotics design and hardware design would be helpful but not essential. The project should be completed in a timely manner and I am confident that the right developer can help me achieve my desired results.
