• Strong experience in optical and multiphysics simulation of complex physical systems
• Ability to couple multiple physical domains (optical, thermal, mechanical, fluid)
• Solid understanding of laser and optical physics
• Experience in model validation, uncertainty quantification, and data-driven refinement
• Strong programming skills in Python, MATLAB, or C/C++
• Experience with simulation tools such as COMSOL, ANSYS, Zemax, CodeV, or FRED
• Advanced written and verbal communication skills in English

Preferred Qualifications

• Proven experience developing and maintaining Digital Twin models
• Familiarity with MDO workflows (UQ, DoE, ML training) and metamodelling techniques
• Experience with HPC batch schedulers and automation scripts
• Familiarity with Monte Carlo techniques
• Hands-on R&D testing experience with laser systems or optomechanical assemblies
