What We’re Looking For

We are looking for a hands‑on Siemens PLC programmer and developer, not someone whose experience is limited to monitoring automated equipment or making minor adjustments to existing PLC programs. The successful candidate should be able to independently develop PLC logic, troubleshoot complex control systems, and support automation projects from initial programming through commissioning. The most important qualifications for this position are: Strong Siemens SIMATIC Manager STEP 7 programming experience. Hands‑on development experience with Siemens S7-400 controllers, with S7-300 experience also acceptable. Ability to develop and troubleshoot PLC programs independently. Basic SCADA integration and troubleshooting experience. Willingness to travel up to 50% for field service and customer support. Candidates with extensive experience in other PLC platforms but no hands‑on Siemens SIMATIC Manager STEP 7 development experience would not be the strongest fit for this position.

Physical Requirements

Frequently required to walk, sit, use hands and fingers, and reach with hands and arms. Occasionally required to stand. Frequently lift or move up to 25 pounds and occasionally up to 40 pounds. Ability to work in industrial and manufacturing environments during service visits and commissioning activities.
