Senior PLC Engineer

1. PLC Architecture & Development Design, program, and debug PLC applications using Keyence Ladder Logic and Structured Text for complex, multi-station industrial machines. Develop modular, scalable, and maintainable PLC code with clear documentation and state-machine driven logic. Implement reliable IO control, sequence logic, motion control, interlocks, alarms, and features. 2. Standards, Best Practices & Code Quality Establish and enforce internal PLC programming standards, naming conventions, documentation practices, and version control workflows. Perform code reviews, mentoring, and technical coaching for junior PLC or automation engineers. Ensure all PLC logic follows safe, deterministic, and production-ready design principles. 3. System Integration Collaborate closely with the software team working on PC-based control, ensuring smooth communication between PLC and PC systems (TCP/IP, Ethernet/IP, OPC/other protocols). Coordinate with electrical team on wiring, IO mapping, safety circuits, and panel design inputs. 4. Machine Commissioning & Troubleshooting Diagnose complex automation issues involving sensors, actuators, motion devices, safety systems, and communication interfaces.Support production, maintenance, and customer engineering teams in solving high-impact problems. Able to travel internationally on short notice based on project needs, including machine commissioning, on-site debugging, FAT/SAT, and customer support. 5. Project Execution & Leadership Work with project managers and the software manager to define PLC-related timelines, deliverables, and risks. Ensure all PLC control design meets customer requirements, machine functional specifications, and safety standards. Provide clear technical documentation: control sequence charts, IO lists, state diagrams, and alarm/error handling logic. Requirements Degree in Electrical, Mechatronics, Automation, or Control Engineering (or equivalent). Relevant PLC or automation certifications are a plus. Minimum 7–10 years of hands-on PLC programming experience in industrial automation. Experience with large-scale, multi-station, complex machines. Strong experience with Keyence PLCs. Experience with other PLC brands such as Siemens, Mitsubishi, Omron, or Allen-Bradley is a plus. Experience with machine commissioning, FAT/SAT, and overseas project support. Exposure to PC-based automation environments and MES/OEE integration is preferred. Skillset(s) Requirement Technical Skills: Strong hands-on experience in Ladder Logic and Structured Text programming. Ability to implement machine IO control, interlocks, alarms, and safety systems. Knowledge of industrial communications (Ethernet/IP, TCP/IP, Modbus, OPC, etc.) for PLC-to-PC integration. Ability to define and implement PLC standards, naming conventions, and modular code structures. Understanding of cycle timing, machine states, alarm/error signals, and production counters for OEE/MES integration. Familiarity with motion control, sensors, actuators, servo/stepper systems, and safety devices (E-stop, safety doors, relays). Experience in troubleshooting, debugging, and optimizing PLC systems. Attributes Strong leadership skills; able to mentor junior engineers and enforce best practices. Excellent analytical and problem-solving skills under pressure. Strong communication and collaboration skills, able to work with software, electrical, mechanical, and customer teams. Ability to manage deadlines and adapt to changing project priorities. High level of ownership, responsibility, and commitment to quality standards. #J-18808-Ljbffr
