Nuclear Core Design Engineer information

What are the key skills and qualifications needed to thrive as a nuclear core design engineer?

To thrive as a Nuclear Core Design Engineer, you need a strong background in nuclear engineering, reactor physics, and thermodynamics, typically supported by a relevant engineering degree. Proficiency with simulation and modeling software such as MCNP, SCALE, or CASMO, and familiarity with regulatory codes are essential. Strong analytical thinking, attention to detail, and effective teamwork set standout professionals apart in this field. These skills ensure safe, efficient, and regulatory-compliant reactor core designs, which are critical for nuclear plant operation and public safety.

What are some common challenges faced by nuclear core design engineers during new reactor projects?

Nuclear Core Design Engineers often encounter challenges such as balancing safety requirements with optimal reactor performance during new projects. They must navigate complex regulatory standards, work with interdisciplinary teams, and ensure that their designs account for fuel efficiency, thermal limits, and long-term reliability. Close collaboration with safety analysts, operations staff, and regulatory bodies is essential to address evolving project needs and unexpected technical issues. Staying current with technological advancements and adapting designs to new materials or methodologies is also a key part of the role.

What is the difference between Nuclear Core Design Engineer vs Nuclear Reactor Engineer?

AspectNuclear Core Design EngineerNuclear Reactor Engineer
Primary FocusDesigning and optimizing nuclear reactor cores for safety and efficiencyOperating, monitoring, and maintaining nuclear reactors during operation
Required CredentialsEngineering degree, often with specialization in nuclear engineering, certifications in reactor safetyEngineering degree, nuclear engineering background, reactor operation licenses
Work EnvironmentDesign labs, research facilities, engineering officesReactor sites, power plants, operational control rooms
Industry UsageUsed during reactor design, development, and safety analysis phasesActive during reactor operation, maintenance, and troubleshooting

The main difference is that Nuclear Core Design Engineers focus on designing and optimizing reactor cores before and during construction, while Nuclear Reactor Engineers are involved in the operation and maintenance of reactors once they are active. Both roles require nuclear engineering expertise but serve different stages of the reactor lifecycle.

What does a nuclear core design engineer do?

A Nuclear Core Design Engineer is responsible for designing, analyzing, and optimizing the arrangement and performance of fuel assemblies within a nuclear reactor core. Their work ensures the reactor operates safely and efficiently while meeting regulatory requirements and power output goals. This involves complex calculations, simulations, and collaboration with other engineers to assess fuel utilization, thermal limits, and overall core behavior during various operating conditions.

Company rating: 7.9 out of 10

Based on 59 frontline employees who took The Breakroom Quiz

197th of 487 rated machine equipment manufacturers


Job description

Moog is a performance culture that empowers people to achieve great things. Our people enjoy solving interesting technical challenges in a culture where everyone trusts each other to do the right thing. For you, working with us can mean deeper job satisfaction, better rewards, and a great quality of life inside and outside of work.


Job Title:

Mechanical Design Engineer

Reporting To:

Manager, Design Engineering

Work Schedule:

Onsite - Phoenix, AZ

Mission & Impact

The Mechanical Engineering department at Moog Gilbert is looking for a motivated mechanical engineer to join a team that designs and packages spacecraft electronics. You will own the mechanical elements of integrated avionics units end to end: hardware design and electronics packaging, structural/thermal analysis, documentation, and environmental testing - and you'll see your work directly contribute to mission readiness and customer acceptance. If you bring strong CAD experience with hands on hardware design, we'll train you on Moog's tools and processes (e.g., ANSYS Workbench, SolidWorks, Teamcenter). You do not need every preferred skill to apply; strong candidates typically meet ~80% and show willingness to learn.

What You'll Do


Mechanical Design for Spacecraft Avionics: Design and develop spacecraft avionics assemblies using SolidWorks 3D CAD software. Produce dimensioned and annotated drawings of piece parts and assemblies per ASME Y14.5.
Structural and Thermal Analysis: Develop closed-form and finite element model solutions (using ANSYS Workbench) to address and assess structural and thermal requirements of the design.
Documentation of Results: Produce detailed design reviews and analysis reports documenting design, structural, and thermal analyses.
Environmental Test Planning and Execution: Develop detailed test plans for hardware per customer requirements for vibration, shock, and thermal testing. In-person support of environmental test efforts for integrated avionics units.
Manufacturing Support: Assess mechanical integration/assembly issues and develop solutions to manufacture complex electronics assemblies. Nonconformance assessment and disposition.
Collaborate Cross Functionally: partner with systems, electrical design, manufacturing, test, and program management to meet schedule, cost, and technical goals.

Core Qualifications (Must-Have)


2+ years in a Mechanical Engineering role with emphasis on design and/or structural analysis.
Proficiency in 3D CAD design software (SolidWorks preferred).
Practical experience designing mechanical parts and assemblies.
Experience with closed-form or finite element analysis of mechanical assemblies (thermal and structural).
Strong ability to communicate ideas and results verbally and written.

Preferred Qualifications (We Will Train Where Needed)


Familiarity with spacecraft hardware and requirements.
Experience with electronics packaging and design.
Proficiency in SolidWorks 3D design software.
Proficiency in Finite Element Analysis (ANSYS preferred).
Understanding of Steinberg fatigue analysis of PCB assemblies.
Experience in Teamcenter PLM software.
Experience with random vibration, shock, and thermal vacuum requirements and testing. Previous support of environmental testing a plus.

Growth & Development


Structured onboarding with mentorship and exposure to multiple spacecraft programs.
Targeted training on Moog specific tools/architectures (ANSYS, Teamcenter)
Clear technical progression toward senior mechanical engineering role.
