Lead Engineer – Reactor Thermal-Hydraulics and Computational Methods; Remote Eligible, U.S

Job Description Summary

This role contributes to company objectives in the field of reactor physics and technology. This role is intended for a current or future subject matter expert in the areas of computational methods development/coding, numerical analysis, and thermal‑hydraulics of reactor thermal‑hydraulic modeling tools. This role also supports software documentation and validation, user training, and customer interfacing for the GVH thermal‑hydraulics code TRACG.

The preferred work location for this role is at the GVH Nuclear headquarters in Wilmington, NC (hybrid work arrangements available), but permanent remote work arrangements are also possible.

This role is within the Reactor Physics Technology (RPT) team, which is responsible for the development, maintenance, analytics, technical consultation, and licensing stewardship of engineering computer codes, correlations, and methodologies related to Boiling Water Reactors (BWRs) and Small Modular Reactors (SMRs). RPT is also responsible for supporting customers with emergent questions in the areas of reactor neutronics, thermal‑hydraulics, and instrumentation physics and contributes to the nuclear and thermal‑hydraulic design of new fuel products.

Essential Responsibilities:

• Programming experience with Fortran and Python.
• Responsible for supporting the technical development, accuracy and uncertainty qualification, testing, verification, regulatory licensing, and maintenance of analytical methods required for evaluation of steady‑state and transient core/fuel performance of nuclear reactors.
• Work within an approved regulatory framework for nuclear software quality assurance for engineering computer programs.
• Prepare, document, and present technical data to internal and external customers.
• Contribute to and lead team process improvements to drive speed and simplification.
• Communicate with internal/external users of the methods through support, documentation, and training.
• Ensure work is performed with high quality in accordance with NRC rules and regulations, customer requirements, and business quality assurance standards.
• Drive a team culture based on teamwork, integrity, candor, transparency, and execution on commitments.
• Effectively communicate and coordinate activities with other team members on engineering/technical issues.
• Assist and provide support to the team technical leader and functional manager to plan, status and execute projects.
• Support the interface with various regulatory agencies (NRC, DOE, etc.) as appropriate.
• Honest and straightforward with a high level of personal integrity.
• Detail oriented and accountable for results.
• Strong interpersonal skills and demonstrated ability to work in a team.
• Displays a strong drive for continuous improvement.
• Displays an engaging, can‑do, optimistic attitude.
• Excellent oral and written communication skills.
• Strong analytical capabilities, problem solving skills, and process skills.

Required Qualifications:

• Bachelor’s degree from an accredited university or college in computer science, computational methods, thermal‑hydraulics, nuclear engineering, or a closely related technical discipline AND minimum of 4 years of experience in nuclear methods development/neutron transport/lattice physics/nuclear cross section generation

OR

• Master’s degree from an accredited university or college in computer science, computational methods, thermal‑hydraulics, nuclear engineering, or a closely related technical discipline AND minimum of 2 years of experience in nuclear methods development/neutron transport/lattice physics/nuclear cross section generation

OR

• Ph.D. from an accredited university or college computer science, computational methods, thermal‑hydraulics, nuclear engineering, or a closely related technical discipline with a thesis in computational or numerical methods or nuclear thermal‑hydraulics modeling

Desired Characteristics:

• Ph.D. in computer science, computational methods, thermal‑hydraulics, nuclear engineering, or a closely related discipline.
• Prior experience with thermal‑hydraulic methods (TRAC, GOTHIC, COBRA, ISCOR, etc.)
• Working knowledge of nuclear reactor core licensing, technical…
