Packaging Mechanical Engineer

About the job

About the role Own the thermo-mechanical design of the advanced packages our AI accelerator silicon ships in. A multi-die 2.5D package is a stack of materials that all want to expand at different rates, under a lid, under load, cycling through hundreds of watts — and your job is to make it stay flat, stay bonded, and stay intact. You'll model warpage and stress through reflow and assembly, design the lid, stiffener, underfill and TIM stack that controls them, set the mechanical rules our OSATs build to, and own the socket and load mechanics where the package meets the cooling solution. You'll correlate every model against real measurement, and you'll be the person who knows whether a design…
