Lead optimization and scaling of plasma CVD manufacturing processes, troubleshoot systems, analyze data, and collaborate with teams for improvements.
Summary Generated by Built In
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 highly skilled and motivated Senior Process Engineer with deep expertise in Chemical Vapor Deposition (CVD) to lead the development, optimization, and scaling of advanced plasma-based manufacturing processes. In this critical, hands-on role, you will focus on improving process performance, long-term stability, and product yield within a high-tech, data-driven manufacturing environment.
The ideal candidate will have a strong foundation in process engineering principles, with a demonstrated ability to troubleshoot complex systems, analyze large datasets, and drive root cause investigations. You will collaborate closely with cross-functional teams—including equipment engineering, materials science, product development, and operations—to translate experimental insights and research findings into robust, high-yielding, and scalable production processes.
This role requires both a strategic mindset and strong execution skills, as you will be responsible not only for optimizing existing processes but also for identifying and implementing innovative improvements. You’ll lead process qualifications, design and execute DOE experiments, and work to ensure process reliability and repeatability at scale.
The position offers a unique opportunity to contribute directly to the advancement of cutting-edge CVD technologies in a fast-paced and collaborative setting, where your impact will be visible in production outcomes and product quality.
Responsibilities
- Lead the execution of process optimization initiatives across plasma-based CVD manufacturing equipment, with a focus on throughput, stability, and quality.
- Analyze operational and experimental data to identify trends, correlations, and root causes; generate actionable insights to enhance process control and product performance.
- Design, implement, and track experiments (including DOE-based approaches) to validate improvements and support production scaling.
- Interface with cross-functional teams (R&D, equipment, quality, and product) to introduce new materials, tools, or methods into the production environment.
- Create and maintain technical documentation, including process specifications, standard operating procedures (SOPs), and engineering change notifications.
Requirements
- Bachelor’s (5+ years), Master’s (3+ years), or PhD (1+ year) in Chemistry, Chemical Engineering, Materials Science, Physics, or a related field, with experience in a process engineering role—preferably involving CVD or similar technologies.
- Hands-on experience with complex semiconductor-style plasma CVD manufacturing equipment.
- Proficiency with statistical analysis tools and data visualization (e.g., JMP, SQL, Tableau). And, experience designing and analyzing experiments (DOE, SPC).
- Excellent problem-solving skills and ability to work in cross-functional projects in a fast-paced, production-driven environment.
- Eagerness to learn, grow, and take on new challenges in a dynamic and fast-moving work environment.
