Senior Reactor Design Engineer

Naval Nuclear Laboratory•West Mifflin, NY

About The Position

The Advanced Mechanical Design group is seeking a self-driven mechanical engineer to support new reactor core design development. The role offers an opportunity to contribute at an early stage of a new reactor design in a dynamic, collaborative environment. Near-term work includes developing and structurally evaluating the concept design for the program’s next reactor core, developing mechanical improvements to address existing fleet challenges, and supporting manufacturing development at the laboratories and manufacturing vendor. Evaluations may range from first-principles scoping tools to detailed analyses using structural analysis codes. The successful candidate will work with a diverse team of engineers at the Knolls and Bettis sites and communicate effectively with the team, other core design disciplines, and stakeholder organizations, including materials and manufacturing. Mentoring, training, and guidance are available. The position provides challenging assignments and opportunities to build technical skills and broaden experience. Naval Nuclear Laboratory supports the U.S. Navy’s submarine and aircraft-carrier fleets through naval nuclear propulsion technology, technical support, and operator training.
