Mechanical Engineer

Senior Mechanical Engineer – Nuclear Power Uprate Projects

This Senior mechanical engineering role focuses on supporting power uprate projects at existing nuclear power plants. The position requires at least five years of relevant mechanical engineering experience and an accredited bachelor's degree in mechanical engineering. You will lead the development of design inputs, validate scoping documents for system evaluations, and perform engineering reviews to demonstrate the technical feasibility of power uprates.

You will provide technical leadership on equipment specifications, hydraulic calculations, and datasheet development, while guiding designers and collaborating closely with plant staff, engineering teams, and vendors. The role demands strong judgment, the ability to make sound decisions with limited information, and significant experience in the design of new construction or retrofit projects for power generation or heavy industrial facilities.

• Provide mechanical engineering support to develop design inputs for power uprate projects at existing nuclear power plants.
• Validate scoping documents for system evaluations to ensure completeness, accuracy, and alignment with project objectives.
• Perform detailed engineering reviews of work products to demonstrate the feasibility of power uprate concepts and associated plant modifications.
• Lead the development of equipment specifications and datasheets for valves, tanks, pumps, and balance-of-plant equipment.
• Perform and review hydraulic calculations to support system design, equipment sizing, and overall plant performance evaluations.
• Develop design input requirements and communicate them clearly to designers and other engineering disciplines.
• Provide technical direction and oversight to designers during detailed design activities, ensuring adherence to engineering principles, codes, and standards.
• Review and check engineering reports, drawings, and calculations related to uprate activities and required plant modifications.
• Develop, prepare, and check Piping and Instrumentation Diagrams (P&IDs) for accuracy, functionality, and compliance with design requirements.
• Lead the overall design and layout of piping systems, including pipe sizing, routing, material selection, and pipe support design.
• Select appropriate mechanical equipment and prepare inquiry packages and technical data sheets for procurement.
• Apply significant knowledge of mechanical engineering design principles, as well as applicable codes, standards, and regulatory requirements, to all project work.
• Use engineering software such as FATHOM, PEPSE, or similar tools to support hydraulic and system performance analyses.
• Collaborate effectively with plant staff, design engineering personnel, and vendors to resolve technical issues and advance project objectives.
• Exercise sound engineering judgment and make informed decisions with minimal information, balancing technical, operational, and regulatory considerations.
• Support and contribute to power uprate implementation by considering engineering, operations, and licensing impacts in design decisions.
• Prepare clear, concise technical documentation and reports that support design bases and licensing needs.
• Communicate complex technical concepts effectively to multidisciplinary teams and stakeholders.

• At least 5 years of related mechanical engineering experience, preferably in the commercial nuclear industry or similar power generation or heavy industrial facilities.
• Accredited bachelor's degree in mechanical engineering.
• Significant experience with design of new construction and retrofit projects for power generation or heavy industrial facilities.
• Strong knowledge of mechanical engineering design principles and…
