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

$150,000 - $180,000 a year
