Materials Process Engineer

Diamond Foundry • Bay Area, CA

2d • Onsite

About The Position

Diamond Foundry is seeking a Materials Process Engineer to help develop and scale a proprietary advanced material used in diamond manufacturing. The role involves hands-on work across molding and extrusion, material characterization, and engineering interfaces with diamond and glass substrates. The engineer will help move a novel material from laboratory experiments toward high-volume production, working alongside laser, optical, and manufacturing engineers. The position is based onsite in Fremont, California, five days per week. The role is described as entry-level, though higher-level candidates may also be considered.

Requirements

• BS or MS in Materials Science, Chemical Engineering, Physics, Chemistry, or a related field.
• Entry-level experience of 0–2 years; internships count.
• Internship or direct laboratory experience in glass characterization or molding.
• Familiarity with moderate-temperature processing such as glass or polymer molding and extrusion, surface treatment, and safe handling of toxic materials.
• Experience characterizing thermal, optical, and structural properties using techniques such as DSC, viscometry, UV-Vis, FTIR, XRD, and SEM/EDS.
• Experience using designed experiments and analyzing data with JMP, Python, or Google Sheets.

Nice To Haves

• Experience with chalcogenide or other specialty glasses.

Responsibilities

• Run moderate-temperature molding processes and help design and fabricate molds, tuning temperature, pressure, and surface finish to reduce defects.
• Run extrusion trials and measure how temperature, pressure, and die design affect flow, surface quality, and dimensional consistency.
• Characterize thermal, optical, and flow properties before and after processing, and track changes across reuse cycles.
• Clean and functionalize diamond and glass substrate surfaces, including through plasma treatment, and evaluate adhesion and interface quality.
• Run designed experiments and use the results to develop process improvements.
• Document process improvements in SOPs.
• Follow EHS practices for toxic materials.

Benefits

• Opportunity to enroll in health insurance, flexible spending accounts, retirement savings plans, life and disability insurance programs, and programs providing paid and unpaid time away from work, subject to eligibility.
• Employee discounts to VRAI.
• Benefits begin as early as the first day of employment; medical and vision coverage are retroactive to the start date, while dental and voluntary benefits take effect after enrollment.
