Job Title: Mechanical Design Engineer


Job Description

Join our dynamic Mechanical Engineering team as a Mechanical Design Engineer, where you will play a pivotal role in the development of Small Nuclear Reactor systems. You will be responsible for the engineering design and development of mechanical systems, structures, and components. This includes Reactor Internal Structures, Steam Generator System, Helium Circulator System, Graphite Core Components, Reactor Cavity Cooling System, and Nuclear Auxiliary Systems. Your work will involve concept development, evaluation, and analysis to ensure systems meet technical specifications and requirements.


Responsibilities

  • Develop mechanical and physical concepts, design, and support the development of processes for nuclear products with a focus on safety.
  • Identify, collect, and document requirements, interfaces, design basis, and criteria by coordinating with stakeholders and systems engineers.
  • Plan and perform analysis to ensure systems and components perform their intended functions and meet technical specifications.
  • Perform computations using hand calculations and analytical tooplmls for structural, thermal, hydraulic, and other calculations.
  • Develop innovative mechanical solutions for pressure vessels, reactor internals, nuclear fuel, and high temperature materials like graphite.
  • Integrate design activities across engineering team members, partners, and suppliers.
  • Create and maintain CAD-generated engineering models of reactor structures, systems, and components.
  • Support the assessment of systems for manufacturability, assembly, and integration.
  • Write and develop design documentation including design basis documents, technical reports, calculations, and drawings.
  • Develop Verification and Validation (V&V) plans for analytical tools and support toolset qualification.
  • Perform work in accordance with quality procedures to ensure project quality requirements are met.
  • Provide independent reviews and acceptance reviews of engineering deliverables and data.
  • Maintain a professional demeanor in all forms of communication.

Essential Skills

  • Bachelor’s degree in mechanical engineering or related engineering discipline from an accredited institution.
  • Proficiency with engineering hand calculations.
  • Experience in designing and developing mechanical or fluid systems, assemblies, or components.
  • One plus years of hands-on experience in hardware or manufacturing processes in a production environment.
  • Experience with Computer-Aided Design (CAD) and product lifecycle management (PLM) software such as UG/NX, Solidworks, Pro-Engineer, Teamcenter, or Windchill.

Additional Skills & Qualifications

  • Experience with commercial nuclear power plant operations.
  • Professional experience in design, qualification, licensing, and construction according to industry standards.
  • Experience with NRC regulations and licensing requirements for safety-related systems.
  • Hands-on experience with graphite or non-metallic components, fabrication or assembly sequencing, and tooling development.
  • Experience with procurement and manufacturing oversight of pressure vessel or large metallic components.

Work Environment

The role is based in an office environment, where collaboration with a diverse engineering team is key to success.

Compensation:$85
