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 robust knowledge of nuclear codes and standards as well as hands‑on experience with project management, manufacturing and quality assurance within a highly regulated environment.

Contract Review: Perform customer contract technical review including associated specifications and drawings, and identification of potential product or manufacturing risks. Participate in contract level status meetings and quote level design development meetings with customers as applicable. Prepare and submit contract level documentation, which may include general assembly drawings, specification compliance reports, instruction manuals and others as required.

Conduct research, perform calculations, and create technical designs for custom nuclear components, ensuring alignment with both customer requirements and internal manufacturing capabilities.

Manufacturing Support: Develop detailed plans for manufacturing, including weld and braze design, bills of material and drawing packages.

Project Management: Plan and manage project scopes, including design proposals, progress reports, prototype manufacturing, environmental qualification, data package review and submission.





Engineering Collaboration: Work closely with manufacturing and quality teams to ensure proposed designs are feasible, cost‑effective, and compliant with nuclear safety and regulatory standards.

Problem Solving: Investigate mechanical failures, troubleshoot production issues, assist manufacturing team in development of tooling, equipment and process improvements and provide technical support to departments as required.
