Non-destructive testing or NDT contract jobs include a variety of positions with titles like technician or engineer that focus on testing materials and components as part of a quality control process. In this field, you may look for signs of corrosion, record test results, define the parameters of tests, and coordinate with other personnel as needed. Many NDT contract jobs have specific additional requirements unique to the situation or location. For example, these jobs may require a security clearance so you can work in government facilities or the ability to memorize and follow radiation safety guidelines while working in dangerously radioactive areas. As such, flexibility and the ability to memorize procedures is essential to your success in this role.
