About the Role

This Software Engineer position at Terex Corporation involves developing and maintaining PLC control systems for safety-critical and SIL-rated mobile/off-highway machinery applications. You will design and develop CODESYS-based visualization (HMI screens), Operator interfaces, Diagnostic screens, and Alarm management. Your work will also involve creating and reviewing Functional Design Specifications (FDS) and developing applications using IFM controllers.

Key Responsibilities

• Develop, program, and maintain PLC control systems for safety-critical and SIL-rated mobile/off-highway machinery applications.
• Design and develop CODESYS-based visualization (HMI screens), Operator interfaces, Diagnostic screens, and Alarm management.
• Create and review Functional Design Specifications (FDS).
• Develop applications using IFM controllers (CR series / ecomatmobile).
• Testing & functional validation of code.
• Develop and maintain a strong understanding of IEC 61131-3 programming standards.
• Work independently and on-site without supervision to support machine breakdowns.

Skills & Qualifications

• Strong understanding of IEC 61131-3 programming standards, including Function Blocks Diagram (FBD), Sequential Function Chart (SFC), Structured text, and Ladder Diagram (LD).
• Knowledge on Engine diagnostic tools and communication protocols primarily on CAN, J1939 & EtherNet/IP standards.
• HMI coding, creating good authorization control, and writing scripts for animating the real-time process.
• Good diagnostic skills on basic electrical systems to understand issues, identify requirements, and support at site independently during machine breakdown.
• Ability to read Electrical Schematics, Machine I/O's, BOM, etc. to have a basic understanding on system level.
• Bachelor's degree in Computer Science, Electrical Engineering, or related field.
• Proficiency in programming languages such as C, C++, or Python.
• Experience with simulation setup, testing, and validation of software.
• Knowledge of AC/DC Motors, Drives, VFD's, Control switches, Switch gears, and basic electrical components from design level.
