Principal Semiconductor Materials Engineer

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 hands-on Semiconductor Materials Engineer to design, fabricate, and characterize advanced semiconductor devices in a highly collaborative lab environment. This role is rooted in cleanroom experimentation, thoughtful iteration, and a deep understanding of semiconductor materials & device physics. The ideal candidate is curious, self-driven, and motivated by ownership and impact - someone who enjoys working closely with teammates, taking responsibility for device performance, and tackling technical challenges, including materials integration for high-power and RF device applications.

Responsibilities

• Design and optimize semiconductor materials & associated device structures with a strong focus on fabrication feasibility, process integration, and performance
• Lead and collaborate with engineers in the cleanroom to fabricate devices and associated test structures
• Drive design-fabrication-characterization iteration cycles by adapting processes and designs based on experimental results
• Define, execute, and refine in-depth electrical characterization of fabricated devices to understand underlying carrier dynamics
• Analyze, interpret, and report device measurement data to identify performance-limiting mechanisms and guide improvements

Requirements

• MSc or PhD in Materials Science, Physics, Electrical Engineering, or a related field, with 4+ years of experience designing, fabricating, and characterizing semiconductor devices
• Extensive hands-on experience with semiconductor microfabrication (layout experience required i.e. L-Edit, KLayout, etc), including ownership of fabrication processes in a cleanroom environment
• Deep understanding of semiconductor device physics, including transport mechanisms, interfaces, and reliability
• Strong expertise in device characterization and experimental data analysis; experience with device modeling or simulation (e.g., TCAD, COMSOL, ANSYS) is a plus
• Ability to work effectively in a collaborative, inclusive, and accountability-driven team environment, with excellent interpersonal and communication skills, and a proactive, self-directed approach to work
