This position requires a strong background in C#/.NET development, PLC, motion control, sensor/PCI card integration and industrial automation systems.

You will be responsible for designing robust, real-time applications running on Industrial PCs (IPCs), interfacing with a wide range of industrial components including servo motors, stepper motors, PLCs, cylinders, conveyors, robotic arms, and sensors.

Key Responsibilities:

• Design and implement real-time industrial machine control software in C#/.NET for Windows-based Industrial PCs.
• Integrate with various industrial hardware including servo motors, drives, stepper motors, PLCs (Siemens/Beckhoff/Mitsubishi), cylinders, conveyors, and robotic arms.
• Develop software modules for motion sequences, state machines, safety interlocks, IO control, and HMI interfaces.
• Collaborate with electrical and mechanical engineers to ensure cohesive integration between software and hardware components.
• Work with industrial communication protocols such as Modbus, OPC UA, EtherCAT, Profinet, etc.
• Implement diagnostics, logging, error handling, and troubleshooting capabilities in software.
• Participate in on-site commissioning, functional testing (FAT/SAT), and debugging of machines.
• Create and maintain documentation for code, interfaces, and user manuals.

Key Requirements:

• 3-4 years of hands-on experience developing machine control software in C#/.NET in an industrial environment.
• Proven experience with PLC programming and integration (Siemens or Beckhoff, or Mitsubishi).
