• Contribute to internal standards, best practices, and technical improvement efforts

Job Requirements

Experience: 3-6+ years in industrial automation, with a track record supporting or leading control system projects from design through startup.

Technical Skills:

• Proficient in PLC programming software, with a strong understanding of core instruction sets and IEC 61131-3 programming languages
• Solid understanding of how PLCs operate and communicate with external devices, control systems, and industrial networks
• Ability to debug medium-to-complex PLC programs and build routines or basic systems from scratch
• Proficient in HMI software - screen development, tag database creation, and basic HMI/SCADA application development
• Ability to create functional specifications from P&IDs, system diagrams, customer specs, and stakeholder discussions
• Experience configuring and troubleshooting I/O, remote I/O, VFDs, instrumentation, solenoid manifolds, network switches, and other bus network devices
• Ability to support system architecture and controls design for simple to moderately complex automation solutions
• Experience with startup, commissioning, plant-floor troubleshooting, and customer site support
• Strong customer interaction skills and the ability to work independently onsite

Nice to Have:

• Experience with multiple PLC or HMI platforms (Allen-Bradley, Siemens, Ignition, Wonderware, and others)
• Experience with plant-area HMI models (areas, cells, units)
• Experience with specialized libraries: process libraries or vertical market libraries
• MES, database, or enterprise-level SCADA/DCS experience (a plus for senior-level candidates)
• Experience in OT cybersecurity, secure network design and implementation
• Relevant certifications a plus (e.g. PE, PMP, CSIA, UL508A, GICSP), but not required
