About the role
Thermal Engineer What you'll do: • Developing and running thermal models of conduction, natural convection, and forced air cooled systems. • Providing design feedback via plots and screenshots of thermal behavior and air flow, along with recommendations for how to improve performance. • Designing convective thermal solutions including fans, heatsinks, and vapor chambers, along with conductive thermal solutions including TIMs and TECs. What you have: • 5+ years of experience with thermal analysis and modeling of complex systems including silicon packages, PCBs, and fans. • Proficiency modeling CFD in Siemens FloEFD including transient and steady state analysis. • Understanding of CFD model optimization for reducing run time (meshing strategy, feature resolution, understanding how different components affect the thermal stack, etc). • Experience debugging complex models with multiple boundary conditions including solar loading, pressure inlets/outlets, and fixed temperature cabinet walls. • Experience in designing, speccing, and implementing passive and active thermal management solutions. • B.S. in Mechanical Engineering or related field. • Strong understanding of heat transfer principles, fluid dynamics and thermodynamics. • Experience in designing advanced thermal management solutions such as heat pipes, 2D vapour chamber, 3D Vapour chamber, etc. • Good experience in selection and application of right thermal interface material ( gap filler pad, gels, grease, paste, phase change materials, epoxy etc.) Nice to have • Experience with Multiphysics analysis techniques such as thermal expansion in structural simulation, outputting model results into optical analysis (STOP), etc. • Experience designing thermal solutions for automotive components. • Deep understanding of the thermomechanical properties and failure modes of glass, laminated composite structures, ceramics, polymers, metals, and adhesives. • Solidworks modeling experience Application for Thermal Engineer successfully submitted!
