R&D Process Engineer, Advanced Bonding Process Development

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.

Responsibilities

-

Support customer prototyping projects to integrate single-crystal diamond with customer devices and demonstrate thermal and performance benefits.

-

Develop advanced packaging and bonding processes adaptable to diverse customer device designs, material stacks, package configurations, and integration requirements.

-

Evaluate, select, and optimize bonding technologies, including pressure/pressureless sintering, thermocompression, surface/plasma-activated bonding, and emerging methods.

-

Drive internal process development and validation, including cleaning, metallization, DOE-based bonding optimizations, process characterization, failure analysis, and reliability testing.

-

Manage end-to-end project execution, covering schedules, technical risks, cross-functional communication, customer updates, and technical reports.

Requirements

-

Bachelor’s or advanced degree in materials science, electrical engineering, chemical engineering, or a related field.

-

Experience in semiconductor packaging, advanced materials, process engineering, device integration, or related technical development is preferred.

-

Familiarity with bonding, thin-film deposition, surface preparation, metrology, failure analysis, reliability testing, or similar process technologies is desirable.

-

Strong problem-solving skills and willingness to learn new materials, tools, and processes.

-

Good communication skills and ability to work effectively with cross-functional teams, hands-on, detail-oriented, motivated, and comfortable working in a fast-paced development environment.
