• Hands-on experience in thermal management using CFD or FEA.
• Proficiency with at least one CFD tool: Ansys Icepak, Fluent, Simcenter FloTHERM, Comsol Multiphysics, CFD++, or similar.
• Proficiency with at least one FEA tool: Ansys Mechanical, Abaqus, or similar.
• Solid grounding in heat transfer, fluid mechanics, solid mechanics and material behavior.
• Experience importing and simplifying CAD (Creo, SolidWorks, NX, DesignModeler, Space claim).
• Strong communication and reporting skills.

Responsabilidades

• Build and run conjugate heat transfer (CHT) simulations at system, board and component level.
• Model the thermal behavior of SoCs, PMICs, batteries, displays and other heat-dissipating parts.
• Run transient analyses of power profiles and support thermal throttling and power budget strategy.
• Evaluate cooling solutions: heat spreaders, graphite sheets, vapor chambers, TIMs and airflows.
• Run thermo-mechanical stress and warpage analysis on PCBs, solder joints, packages and enclosures.
• Predict solder joint fatigue and reliability under thermal cycling.
• Couple CFD temperature fields into FEA for multiphysics evaluation.
• Turn simulation results into clear design recommendations for cross-functional teams.
• Correlate models with lab data (thermocouples, IR thermography, thermal chambers).
• Help define thermal test plans and DVT/PVT validation.
• Run DOE, sensitivity studies and optimization.
