#Design #Mechanics #Stellarator

We are looking for talented mechanical engineer to design and simulate new products, parts, equipment, or mechanical machines within the Liquid Metal Department - and supervise their manufacturing to support the long-term project of construction and integration of the stellarator.

Your main responsibilities will be:

*Mechanical design

  • Define and size mechanical solutions to meet the required specifications of custom-made parts for the on-site construction of first-of-a-kind machines /prototypes taking into account manufacturing constraints, operating environment (such as vacuum, temperature)
  • Conceive innovative designs and realize their detailed 3D Computer Aided Design (CAD) models.
  • Coordinate with her/his team members to integrate the input and output data of each project: integrate and interface the different parts of the design as required (mechanical, electrical, thermal, chemical, nuclear, material and/or vacuum perspective)
  • Generate computer models suitable for simulation, fast prototyping and other R&D and commercial purposes; integrate feedback from simulations and tests to iteratively optimize designs
  • Perform stack-up analyses (fits, misalignments)
  • Create and update the definition data: bill of materials, drawings of parts and assemblies, technical notes

*FEA modeling

  • Carry out multi-physics numerical simulations of supplied 3D CAD models (Structural Mechanics, CFD, Heat Transfer, etc...)
  • Update and maintain simulation results, in coordination with the update and maintenance of design files
  • Integrate and interface the different parts of the design as required (mechanical, electrical, thermal, chemical, nuclear, material and/or vacuum perspective)

*Manufacturing

  • Participate when needed in the search for suppliers of components and/or manufacturing companies and collaborate with them on technical aspects
  • Supervise and/or participate in the in-house or outsourced construction of parts, equipment or mechanical machine

Requirements

Please do not hesitate to apply even if you don't meet all our requirements. Superheroes do not exist - but people with passion and talent do!

*Education and professional experience

  • Master’s or Bachelor’s degree + equivalent experience in mechanical engineering or related field
  • Experience in machine design and/or FEM simulations of complex systems and in manufacturing

*Languages

  • Fluent in English (C1)
  • Knowledge (B1 or higher) of French is a plus

*Technical skills

  • CAD design software such as SolidWorks, Inventor…
  • ANSYS, COMSOL Multiphysics or other finite element software
  • Knowledge of numerical modelling of scientific or industrial relevance
  • Understanding of the mathematical basis of FEM modelling
  • Coding in Python, Matlab or other programming language, as well as knowledge in machining techniques, is a plus
