Device Engineering Intern

Diamond Foundry
Bay Area, California, United StatesinternshipVerifiedPosted 27 Apr 2026

About the role

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 summer intern to support semiconductor materials preparation and advanced characterization in a highly collaborative lab environment. This role focuses on sample fabrication alongside in-depth analysis to understand material structure and properties, and 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 for high-power diamond-based electronics.  

This position would operate out of our Stanford office and our South San Francisco office.

Responsibilities

  • Design and optimize semiconductor materials & associated device structures
  • Collaborate with engineers in the cleanroom to fabricate devices and associated test structures
  • Lead in-depth characterization of devices using techniques such as TEM, SEM/FIB, and XPS, and correlate results to electrical performance
  • Develop and execute sample preparation workflows (e.g., cross-sectioning, FIB lift-out) to enable high-quality characterization
  • Analyze, document, and communicate experimental results to guide process and device improvements

Requirements

  • Ability to work effectively in a collaborative, inclusive, and accountability-driven team environment, with strong communication skills and a proactive, self-directed approach to work

  • MSc or PhD (in progress or completed) in Materials Science, Physics, Electrical Engineering, or a related field, with experience in semiconductor materials or devices

  • Hands-on experience with semiconductor microfabrication and subsequent materials and/or electrical characterization

  • Understanding of semiconductor device physics, including transport mechanisms, interfaces, and reliability

  • Experience with device or materials characterization and experimental data analysis; familiarity with modeling or simulation tools is a plus
