• Initially supporting the reactor licensing process in the United States

By partnering with them, we have the opportunity to contribute to a rapidly growing scaleup, aiming to become a leading technology provider in global energy solutions.

Committed to innovation and sustainability.

Mechanical Systems Designer Responsibilities

• Designing, developing, and optimizing mechanical systems and components for nuclear power plants, research reactors, and other applications.
• Creating detailed technical drawings and collaborating with engineers and regulatory agencies.
• Ensuring designs meet nuclear safety, performance, and regulatory standards.
• Using CAD software (AutoCAD, SolidWorks, CREO) to develop 2D and 3D models, perform mechanical analyses, and support prototype development and testing.
• Conducting material selection, stress analysis, and thermal analysis for optimal performance under high‑radiation and high‑temperature conditions.
• Adhering to industry regulations and codes, including ASME BPVC, NRC guidelines, and ANSI standards.
• Assisting in prototype development and testing, troubleshooting nuclear mechanical systems.
• Preparing technical documentation, including design specifications, engineering reports, and BOMs.
• Revising designs based on feedback (testing results, manufacturing input, regulatory requirements), maintaining organized design files and version control.
• Supporting the product lifecycle management (PLM) process, including design updates and safety improvements.

Candidate Profile

• Education: Master’s degree in Mechanical Engineering, Nuclear Engineering, or related field.
• Experience: 2–5 years in mechanical design for nuclear applications, power plants, or industrial settings.
• Preferred certifications: CSWP, AutoCAD certification, or equivalent.
• Proficiency in CAD software: AutoCAD, SolidWorks, CREO.
• Knowledge of mechanical design principles for nuclear applications, including material properties and manufacturing processes.
• Understanding of nuclear reactor components: cooling systems and radiation shielding.
• Familiarity with ASME BPVC, NRC regulations, and ANSI standards for nuclear mechanical design.
• Experience with finite element analysis (FEA); CFD for nuclear applications is a plus.
• Experience in tribology, seals, and welding.
• Strong problem‑solving and analytical abilities.
• Effective communication and teamwork skills.
• Attention to detail and project management skills; ability to manage multiple projects and meet regulatory deadlines.
• Preferred: PhD or advanced engineering degree.
• English (written and oral).
• Soft skills: passion for engineering, ability to build relationships and influence at all levels.
