- Familiarity with:
- PLCs (Allen-Bradley, Siemens)
- HMIs and SCADA systems
- VFDs, instrumentation, and field devices
- Prior experience designing control panels for industrial or municipal applications
Work Structure

- Moves quickly on smaller projects without heavy oversight
- Communicates clearly and proactively with the team
- Helps reduce bottlenecks in design and submittal turnaround
