Mechanical Engineering Intern

Hadron Energy specializes in developing, designing, and researching micro modular reactors that provide carbon-free power. The Mechanical Engineering Intern will support mechanical design, drafting, analysis, documentation, testing, and design optimization for reactor components and Balance of Plant equipment while collaborating with multidisciplinary engineering teams.

Responsibilities:

• Support mechanical design and drafting of reactor components, assemblies, systems, and Balance of Plant equipment
• Develop and update 3D CAD models, engineering drawings, assemblies, and design documentation
• Assist engineers with component design assessments, trade studies, and design optimization activities
• Support development of dimensions, tolerances, material specifications, and component interface requirements
• Assist with basic mechanical engineering calculations involving loads, stresses, heat transfer, fluid systems, or component performance
• Work with senior engineers to incorporate design changes and engineering feedback into CAD models and drawings
• Support design-for-manufacturing and assembly (DFMA) activities to improve manufacturability, simplicity, and cost
• Assist with preparation and maintenance of bills of materials (BOMs), component specifications, and technical documentation
• Support engineering reviews, design verification activities, and resolution of technical action items
• Research components, materials, manufacturing processes, and applicable engineering standards
• Coordinate with structural analysis, materials, manufacturing, procurement, and systems engineering teams as required
• Assist with prototype development, testing, vendor interactions, and component qualification activities
• Maintain organized engineering files and documentation in accordance with Hadron's engineering and quality processes
• Present technical work and project progress to engineering team members and leadership
