the posting

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 are seeking an on-site R&D Test Engineer to join our AI Chips team. This role will work closely with the thermal/mechanical/reliability lead to execute thermal testing, coordinate reliability testing, design and develop custom test hardware and fixtures for customer prototyping of single-crystal diamond applications on AI customer chips, and generate engineering insights that guide customer engagements and product development.

The ideal candidate is a hands-on thermal or mechanical engineer with strong technical problem-solving skills, a collaborative mindset, and the ability to support fast-paced customer and internal development programs.

This position will be located out of our San Jose office.
