Headquartered in San Francisco, California, Diamond Foundry is a technology firm that specializes in the production of lab-grown diamonds and high-performance single-crystal diamond wafers. The company leverages zero-emission, proprietary plasma reactor technology to manufacture synthetic gems for the luxury jewelry market as well as diamond substrates for semiconductor applications. Additionally, it supplies ultra-thermal conductivity solutions to optimize power efficiency in advanced microelectronics, electric vehicle systems, and artificial intelligence hardware.

Diamond Foundry is seeking a Principal Laser Process Engineer to oversee the deployment and optimization of high-power laser machines across our various facilities. You will coordinate the development of new ablative processes by working with cross-functional teams of mechanical, electrical, automation, optical, software, and systems engineers to improve and deploy these technologies company-wide. In addition to performing hands-on experiments and developing cutting-edge processes, you’ll be helping mentor team members in performing rigorous, well-designed experiments and making fact-based decisions.

Responsibilities

  • Optimize high-power ablative laser processes to deliver micron-precision dimensional modification of diamond at high yields and throughput.
  • As a principal engineer, you will not only perform hands-on experiments but also mentor team members in using lab and production equipment to generate data-driven process improvements.
  • Lead key projects focused on equipment and automation improvements to support scalable manufacturing.
  • Serve as a subject matter expert, overseeing laser and related processes while optimizing process controls and data collection to drive continuous improvement.
  • Revolutionize high-power ablative systems to create world-leading throughput and precision performance.

Requirements

  • Advanced degree in Materials Science, Applied Physics (materials, laser, or optics focus), or Engineering with a minimum of 8+ years of relevant experience.
  • Expertise with applying optical fundamentals, laser materials processing, and resolving technical problems in a fast-paced manufacturing environment.
  • Experience in rigorous experimentation, documentation, and data-driven process improvements.
  • Experience with mass production of diamond, semiconductors, and/or ceramics is a plus.
