Hours:

Approximately 20-40 hours/month, as-needed and project-driven The Opportunity Mercer Controls is looking for a sharp, experienced PLC Programmer to pick up project work as it comes in -- no fixed schedule, no long commute, just solid pay for solid programming. If you're a controls pro who wants extra income on your own terms and can jump between Modicon, Siemens, and Allen-Bradley platforms without missing a beat, we want to talk to you. Workload runs 20-40 hours a month depending on what's active, so this is a side gig, not a second job -- though for the right person, it could grow into more down the road.

We design, build, and service custom control systems for municipal infrastructure and utility customers. As we continue to grow, we are focused on being the most responsive and most trusted controls company in Texas.
