Job description

CFD Engineer Specialist

The CFD Engineer Specialist will support engineering and licensing requirements, leading to the licensing and construction of the first SMR-300 plant. The engineer will use, and have the opportunity to learn, various methods and software to perform the analyses. The Engineer will be part of a team executing a U.S. Government cost‑shared development program requiring the efficient completion of engineering assignments, including coordination with other engineers in U.S. and offshore operating centers.

Location: Camden, NJ (On‑site)

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.
• Author and review technical reports, calculation packages, and licensing documentation in compliance with NQA‑1 and NRC regulatory frameworks (e.g., RG 1.203) to support the reactor's Preliminary and Final Safety Analysis Reports (PSAR/FSAR).

Requirements

• Advanced degree in Mechanical or Nuclear Engineering with a focus on thermal‑hydraulic analysis and design.
• 5+ years of experience in CFD and thermal‑hydraulics.
• Proficient in ANSYS (Fluent, CFX, Workbench), STAR-CCM+, meshing tools, and SpaceClaim.
• Strong knowledge of heat transfer, fluid dynamics, and CFD turbulence models.
• Familiarity with two‑phase flow modeling.
• Programming skills in Python, C++, or Java for automation and post‑processing.
• Excellent analytical, problem‑solving, and computer skills.
• Strong technical writing, communication, and organizational abilities.
• Detail‑oriented with a focus on accuracy and error‑free work.
• Eligible to work under 10 CFR Part 810.
• MS or PhD in Mechanical Engineering, applied mechanics, or closely related field of engineering (preferred).
• Industry experience using CFD simulation to support product development.
• Experience working with engineers and fabricators to develop designs and drawings.
• Experience with SolidWorks, AutoCAD, and ANSYS software.
• Knowledge of ASME Section III compliance and NRC regulatory frameworks for code validation is a major plus.
• Experience working in the nuclear industry.

Compensation

• Annual compensation based on skills and experience ranging from $95,000 to $115,000.

Benefits

• Industry‑leading medical, dental, and vision coverage with a generous employer premium contribution and Day 1 eligibility.
• FLEX Program – Hybrid work opportunities available for eligible roles, where business needs and role requirements allow.
• 401(k) retirement plan with up to a 5% company match and immediate vesting to support long‑term financial security.
• Paid time off and 11 paid holidays to support rest, balance, and recharge.
• Wellness program offering rewards for participation in company‑supported health initiatives.
• Commuter benefits supporting mass transit and commuter parking options.
• Company‑paid life and AD&D insurance for added peace of mind.
• Education assistance to support continued education and professional growth.
• Employee support and voluntary benefits, including an Employee Assistance Program and optional coverage such as disability, legal, identity theft, and insurance programs.
