Mechanical engineer
Renaissance Fusion
Office
Grenoble, France
Full Time
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
