Mechanical Engineer

The Mechanical Engineer will be responsible for the design, analysis, and creation of documentation to support production of specialized nuclear fabrications, ensuring they meet strict safety, quality and regulatory and customer-imposed standards. These instruments are critical for monitoring and controlling reactor core conditions—neutron flux, temperature, and pressure to ensure safe and efficient operation.

Key responsibilities for this role include performing Engineering analysis, developing manufacturing process plans, reviewing designs and shop capabilities and coordinating with departmental teams to ensure projects are completed on time and meet all requirements. The Mechanical Engineer will work closely with our Sales and Applications staff to support major nuclear utilities as well as emerging SMR (Small Modular Reactor) operators. This role requires strong knowledge of nuclear codes and standards as well as hands-on experience with project management, manufacturing and quality assurance within a highly regulated environment.
