- Demonstrated experience designing, programming, testing, commissioning, and troubleshooting PLC- and HMI-based industrial control systems.
- Working knowledge of instrumentation, process control, feedback loops, interlocks, permissives, alarms, sequencing, and industrial communication networks.
- Ability to create and interpret control narratives, functional specifications, I/O lists, P&IDs, electrical drawings, network diagrams, test protocols, and operating or maintenance documentation.
- Experience with structured software development, source/version control, peer review, defect tracking, release management, and controlled change processes.
Nice to have
- Experience with Rockwell Automation Studio 5000 / RSLogix, Siemens TIA Portal, Schneider Machine Expert, or comparable PLC platforms.
- Experience with industrial HMI/SCADA platforms such as FactoryTalk, Ignition, or GP-Pro EX.
- Exposure to C, C#, Python, SQL, scripting, APIs, data historians, edge computing, or industrial data platforms.
- Exposure to simulation, model-based systems engineering, digital twins, data analytics, machine learning, or AI-assisted engineering workflows.
- Experience with high-purity gas systems, semiconductor equipment, hazardous processes, functional safety, or regulated manufacturing environments.
