Job Description
Build and prove the systems that bring America's first advanced nuclear fuel fabrication facility to life. As a Commissioning Test Engineer at TRISO-X in Oak Ridge, TN, you'll lead the complex, high-stakes testing that demonstrates our facility systems perform exactly as designed and are ready for safe operation. Working with considerable independence under the general direction of the Commissioning Manager, you'll own the toughest elements of the systematic testing program — developing test procedures, directing and performing component and system testing, and rigorously verifying that mechanical, electrical, instrumentation and control (I&C), and process systems meet every design specification. You'll also lead the critical system turnover activities that move facilities from construction to commissioning and from commissioning to operations, serving as a technical anchor who mentors less experienced engineers and partners closely with Responsible Engineers, Operations personnel, Maintenance craft, and QA inspectors to resolve complex technical issues.
