ATR Fitter 1st Class

Idaho National Laboratory is hiring a Fitter to work on our Advanced Test Reactor (ATR) Maintenance team. Our team works a 4x10 schedule located out of our ATR facility with every Friday off. You will perform maintenance and installation of piping, tubing systems, and components.

The Advanced Test Reactor at Idaho National Laboratory is one of the most unique and consequential facilities in the world. As the nation's most powerful research reactor, ATR drives breakthroughs in nuclear fuel development, materials science, and national security-work that directly shapes America's energy independence and defense capability. The systems that keep ATR operating do not maintain themselves. That is where you come in.
