Field Service & Commissioning Technician – Water & Wastewater

This is not a desk job – and that is the point. You will be one of the people who makes engineered systems work in the real world. As one of INFRASTRUCTURE DYNAMICS’ primary field representatives, you will travel to project sites across the lower 48 states, work directly with contractors, operators, and customers, and support installation, startup, commissioning, troubleshooting, service, and warranty activities.

This role carries real responsibility. You may be the first person to spot a field condition that could become a larger problem, determine what can be resolved on site, and clearly flag what needs engineering support. Your observations and experience will feed directly back into engineering and product improvement. If you like working with your hands, solving problems under real‑world conditions, taking ownership from arrival through resolution, and learning across pumps, controls, instrumentation, treatment systems, and fabricated infrastructure, this is an opportunity to grow with a company that wants field experience to help shape what we build next.
