Thermal Mechanical Engineer

The role

You will perform structural and thermal simulations to optimize the design of electro-optical sub-assemblies. This work impacts the performance and reliability of quantum computer sub-systems.

What you will do

• Develop detailed FEA/CFD models of components, packages, optical-electronic modules, and system-level assemblies
• Correlate FEA results with experimental measurements, prototype test data, and hardware observations
• Perform warpage and deformation analysis for multi-material assemblies
• Develop thermal cycling and mechanical fatigue models to predict long-term reliability
• Identify mechanical risk drivers and recommend design, material, or process changes
• Analyze failures related to electro-optical assembly design and provide solutions
• Perform general design activities such as requirements management, materials selection, FMEA, and tolerance analyses
• Develop end-to-end simulation workflows to automate processes
• Document and communicate results through technical reports, design reviews, and executive summaries

Required qualifications

• M.Sc., or Ph.D in Mechanical Engineering, Electrical Engineering and Physics or related field
• 5+years of hands-on modeling and simulation experience in the semiconductor industry
• Strong understanding of thermal conduction and convective heat transfer methodologies
• Deep knowledge of solid mechanics principles, including stress, strain, fatigue, creep, constitutive models of elastic, visco-plastic, and plastic materials
• Proficiency with simulation tools such as ANSYS (Mechanical, Icepak and Fluent), COMSOL, or equivalent, including nonlinear and transient analyses
• Working knowledge of lab-scale validation techniques

Nice to have

• Experience with Ansys AEDT and Ansys Sherlock
• Understanding advanced semiconductor packaging, solder joints, and reliability modeling techniques
• Knowledge of common optical system specifications and optical component specifications
• Exposure to SOC thermal mechanical analysis
• Exposure to optical structural analysis
