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 a Mechanical Designer to support the Gas Systems engineering team with the mechanical design and detailing of process skids, test-bench equipment and mechanical assemblies for pilot-line and facility projects in Zaragoza. The Mechanical Designer works under the lead of a senior designer, who drives the conceptual design, and is responsible for turning that direction into complete, fabrication-ready drawing packages.



The role offers strong technical exposure within a long-term engineering programme and the opportunity to deepen process-systems expertise through close collaboration with senior engineering.

Responsibilities

-
Mechanical Design & Modeling: Developing detailed mechanical designs, advanced 3D models, and 2D manufacturing drawings for gas handling and conversion equipment using SolidWorks. Ensuring design feasibility, analyzing constraints, and guaranteeing seamless integration with existing plant systems.
