Thenuclearcompany Staff Mechanical Engineer at The Nuclear Company to lead design, analysis, and maintenance of complex mechanical systems for nuclear power plants and advanced reactor projects. Provide technical guidance and resolve mechanical issues using engineering software and codes.

Responsibilities

The Staff Mechanical Engineer will be a technical lead responsible for designing, analyzing, and maintaining complex mechanical systems and components for nuclear power plants (operating or a new build) or advanced reactor projects. They will work with a multi-discipline team of engineers in the design, analysis, and evaluation of systems and components using engineering software, including support to lead engineers. They apply advanced engineering principles and engineering codes & standards, such as AMSE and ANSI, to develop solutions that meet strict safety, regulatory, and quality standards. They will resolve technical issues for operating nuclear power plants, new plants, and other nuclear and non-nuclear projects. This role supports Corporate initiatives as well as ongoing construction projects.
Design and analysis of mechanical components and systems.
Prepare engineering calculations, drawings and specifications.
Prepare or review engineering modification packages.
Provide technical guidance to junior engineering staff.
Diagnose mechanical equipment failures, support root cause analyses, and implement corrective actions.
Conduct calculations and analyses to ensure the structural integrity and performance of mechanical systems.
Review vendor documentation and technical specifications.
Participate in design reviews and technical meetings.
Interface with engineers in other disciplines such as civil/structural, electrical and instrumentation and controls (I&C).
Support the implementation of quality assurance and quality control programs.
Prepare technical reports and documentation.
