Description
Diamond Foundry Inc. is solving the thermal limitation at the foundation of today's most exciting tech industries -- AI & cloud compute, electric-car power electronics, and 5G/6G wireless. We have managed to produce the world's first single-crystal diamond wafers and are now on a mission to put a diamond behind every chip. We are the rare unicorn that has grown fast and profitably. We received $515m in funding and are executing a multi-$B expansion plan for one of the greenest forms of tech manufacturing: converting greenhouse gas into diamond wafers using zero-emission energy. We’re looking for an ambitious Mechanical Engineer to take responsibility for designing capital equipment and facilities systems, working across multiple engineering disciplines. You'll be working with an experienced team of mechanical and electrical engineers to take a pragmatic approach to equipment and facility design. You’ll be responsible for whole projects, pulling in the talents of others when needed. This position will work out of our South San Francisco location.
