CFD Engineer Specialist

Primary Responsibilities

• Develop new and innovative Computational Fluid Dynamics (CFD) simulations related to nuclear power plant components.
• Collaborate in small teams focused on the development and execution of complex multi-physics flow simulations, including conjugate heat transfer.
• Apply developed and developing capabilities to directly impact design processes and minimize the need for hardware testing.
• Provide actionable component-level and/or system-level design recommendations to Design Responsible Engineers by interpreting complex analysis results.
• Participate in product design and development teams, presenting analysis results to engineering peers and management.
• Enhance concept designs based on limited requirements or functions and develop mature requirements by gaining an understanding of the system, structure, or components.
• Transform concept designs into license ready designs through critical thinking, literature research, collaboration with team members from other disciplines and vendors, and any analysis permitted by project milestones.
• Support the preparation of design deliverables, presentations, and communicate design progress in stakeholder meetings.
