Posted on Thursday, September 7, 2023
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're seeking a highly skilled and experienced Senior R&D Process Engineer to pioneer the development of processes enabling the application of diamonds in AI chips and power electronics. As an integral part of our seasoned team of mechanical, electrical, and materials engineers, you will play a key role in advancing the development of the reactive ion etch process and plasma-activated bonding process. An ideal candidate brings expertise in vacuum processes and a track record of on-time, within-budget project delivery through effective cross-functional teamwork.


  • Develop RIE and other surface treatment processes for single crystal diamonds to meet the requirement for technology applications.
  • Develop diamond to Si wafer bonding process and associated processes to prepare the to-be-bonded surface including plasma etching/activation, and deposition of the intermediate layers.
  • Design and execute DOE to optimize the process to achieve high quality, low cost, and good manufacturability.
  • Develop process control schemes and create comprehensive documentation for the operation team to ensure a smooth production ramp.
  • Engage with equipment vendors to facilitate tool acquisition, installation, and qualification.
  • Drive the identification and resolution of technical issues and implement corrective actions as needed
  • Collaborate closely with cross-functional teams, across multiple disciplines to address challenges and ensure seamless coordination and execution of critical projects


  • Minimum of 5 years of experience in vacuum process or related roles in the semiconductor, HDD, MEMS, or related industry.
  • Strong technical background in vacuum processing technologies and equipment.
  • Hands-on experience on RIE, IBE and/or PVD/CVD thin film deposition.
  • Solid understanding of surface and substrate roughness, cleanness, flatness, and warpage characterization metrologies, including AFM, WLI, profiler, CSAM, and CLSM.
  • Skilled in statistical data analytics, including DOE, JMP, SPC, APC and FMEA, and experienced in Lean Manufacturing methodologies and practices.
  • Effective communication and ability to thrive in a cross-functional development team.
  • The position requires the successful candidate to be onsite at Fremont and San Jose facilities.
