PsiQuantum is hiring a thermal mechanical engineer in its system engineering department to support electro-optical sub-assemblies used in its quantum computer systems. The role involves FEA and CFD modeling with tools such as ANSYS or COMSOL, correlating simulations with test data, analyzing warpage, thermal expansion mismatch, fatigue, creep, and assembly failures, and recommending design or material changes. The posting asks for an M.Sc. or Ph.D. and at least five years of semiconductor modeling experience, with lab validation knowledge. The work is tied to hardware reliability for a silicon-photonics quantum-computing architecture.
