UT Technician - Field Based, US

Job summary

GWT’s Field Ultrasonic / NDT Technician is responsible for performing advanced non-destructive testing (NDT) inspections on wind turbine blades and composite structures using ultrasonic testing (UT) and supporting NDT methods. This role provides critical structural integrity data that supports blade life extension, root cause investigations, repair scope development, and return-to-service decisions. This position requires domestic and international travel, the ability to work at height and in confined blade spaces, and a high level of technical and safety discipline. Technicians work closely with field repair crews, engineering teams, and customer representatives to ensure data is collected, interpreted, and documented to the highest industry standards.
