Sr Production Crystal Growth Technician
About The Position
The Sr Production Crystal Growth Technician will be responsible for preparing, verifying, and documenting raw materials, dopants, seeds, and charge calculations. They will assemble and inspect hot zones, set up, operate, and monitor CZ growth systems for SGGG production, and support additional oxide systems. The role involves maintaining operational control of key growth parameters, identifying and responding to process drift or equipment instability, and executing controlled heat-up, growth, and cooldown sequences. The technician will perform in-process and post-growth evaluations, record process data, participate in root-cause investigations, and train/mentor junior technicians. Adherence to safety and high-temperature operating standards is crucial.
Requirements
- Minimum eight (5) years of experience in CZ crystal growth or high-temperature oxide manufacturing
- Proven ability to independently operate complex crystal growth systems in a production environment
- Strong knowledge of thermal management, melt behavior, and process repeatability
- Experience with controlled documentation, deviation management, and manufacturing discipline
- Demonstrated troubleshooting capability for crystal growth systems and infrastructure-related disruptions
- Mechanical aptitude for hot zone assembly and equipment upkeep
- Proficiency in data entry systems and Microsoft Office tools
- Strong attention to detail, safety awareness, and process ownership mindset
Nice To Haves
- Associate degree in Engineering Technology, Materials Science, or related technical discipline
- Experience with SGGG and/or similar high-temperature oxide materials
- Experience supporting transition from development to standardized production
- Experience mentoring less-experienced technicians
Responsibilities
- Prepare, verify, and document raw materials, dopants, seeds, and charge calculations per controlled procedures
- Assemble and inspect hot zones to ensure mechanical integrity and thermal symmetry
- Set up, operate, and monitor CZ growth systems for SGGG production; support additional oxide systems as needed
- Maintain operational control of key growth parameters to ensure repeatable execution within defined process windows
- Identify and respond to process drift, equipment instability, or infrastructure-related interruptions
- Execute controlled heat-up, growth, and cooldown sequences to minimize thermal stress and yield loss
- Perform in-process and post-growth evaluations in compliance with traceability and quality requirements
- Accurately record process data, deviations, and observations in controlled documentation systems
- Participate in root-cause investigations related to yield loss and equipment stability
- Train and mentor junior technicians; review setups for procedural compliance
- Maintain strict adherence to safety and high-temperature operating standards
Benefits
- Coherent Corp. Corporate EHS standards
- ISO 9000, 9001, 14001 and/or other applicable standards
