Mechanical engineer experienced in FEA simulations

Within Mechanical Engineering Group (MEG) of the Instrumentation Services and Development Division (ISDD), you will be part of a multidisciplinary team of engineers and technicians responsible for the design and development of high-performance scientific instruments used on our beamlines and accelerator complex of the ESRF. These cutting-edge projects involve ultra-high precision mechanics, opto-mechanics, vacuum technologies, and advanced cooling systems.

Working closely with senior experts and scientists, your role will focus on predictive modeling and performance analysis of our mechanical systems through simulations and calculations.

Your main responsibilities will be to:

• Perform Finite Element Analysis (FEA), multi-physics simulations, and analytical calculations to support the design and optimization of instruments.
• Contribute directly to design reviews and collaborate with physicists and engineers throughout the development process.
• Deliver technical reports and communicate results clearly to project teams and scientists, both in written form and presentations.
• Occasionally represent the group in scientific conferences.

Your key missions:

• Thermal and thermo-mechanical simulations of components exposed to high heat loads: X-ray optics, heat absorbers, temperature-controlled assemblies, etc.
• Structural and vibration analysis to ensure mechanical stability and dynamic performance: high-precision mechatronic systems, vacuum chambers, support structures, and opto-mechanical devices.
• Computational Fluid Dynamics (CFD) studies of cooling systems.

In the short term, your main objective will be to support the design of complex opto-mechanical instruments through Finite Element simulations.

In the medium term, you will expand your scope to include thermal and dynamic modeling using tools such as MATLAB/Simulink.
