Mechanical Engineer – Nuclear, Reactor Systems

This is a fully remote position, open to applicants in United States.

📋 Description

• Design and create mechanical systems and components tailored for the reactor environment, encompassing motion systems, actuators, linkages, structural elements, and safety-related mechanical assemblies.

• Assist in the development of hardware for reactivity control, mechanical actuation, and system-level motion interfaces.

• Execute design trade studies, develop concepts, and select materials.

• Conduct structural and thermal analyses through hand calculations and finite element analysis tools.

• Perform tolerance stack-ups, apply GD&T, and carry out precision mechanical alignment studies.

• Assess fatigue, wear, friction, vibration, and reliability performance metrics.

• Produce manufacturing, assembly, and integration documentation.

• Formulate and implement test plans for components and assemblies.

• Assist with hardware bring-up, test execution, failure analysis, and design iterations.

• Identify and collaborate with suppliers for machined parts, actuators, bearings, materials, and assemblies.

• Ensure components adhere to dimensional, functional, and reliability standards.

• Facilitate design-for-manufacturability and design-for-assembly reviews.

• Collaborate with engineers in nuclear, thermal-fluids, materials, and systems disciplines.

• Confirm that mechanical designs comply with nuclear safety, reliability, and performance standards.

• Contribute to system-level integration across various reactor subsystems.

• Manage projects from inception through to deployment and ongoing operations.

• Enhance internal engineering processes, documentation, and tools.
