Responsibilities

Own and improve crystal-growth processes from charge preparation and furnace setup through growth, cooldown, inspection, and disposition, with a focus on quality, yield, throughput, and safe operation.

Lead a development-heavy portfolio for oxide and garnet materials while providing production-sustaining engineering support for deployed growth methods, including process stability, yield, quality, and equipment capability.

Apply advanced understanding of thermal fields, temperature gradients, pull or translation rate, rotation, atmosphere, pressure, melt chemistry, crucible and hot-zone configuration, and seed orientation to control crystal quality and reproducibility.

Provide technical leadership and hands-on support for Czochralski, Bridgman-Stockbarger, Float Zone, and Skull Melting processes; evaluate method selection and parameter windows for materials and product requirements.

Plan, execute, and analyze structured process experiments and DOE; translate results into controlled work instructions, recipes, process specifications, and training materials.

Investigate growth, material, and equipment excursions using data and root-cause methods; define and verify corrective and preventive actions with Manufacturing, Quality, Maintenance, and Engineering partners.

Use process and characterization data to identify trends in defects, inclusions, stress, cracking, composition, optical performance, and other relevant material attributes; recommend practical process improvements.

Support furnace and ancillary-equipment capability, including preventive maintenance priorities, calibration, controls, sensors, vacuum or inert-gas systems, RF or induction systems, and troubleshooting of equipment-related variation.

Establish and maintain process-control plans, risk assessments, change-control records, and technical reports; communicate results, risks, and recommendations clearly to cross-functional teams and leadership.

Support transfer of new or improved processes from development to production, including qualification runs, acceptance criteria, operator training, and sustained process monitoring.

Promote a strong EHS culture by following applicable procedures and identifying hazards associated with high temperature, vacuum, pressure, inert gases, RF/induction power, and materials handling.

Bachelor's degree in Materials Science, Ceramic Engineering, Chemical Engineering, Mechanical Engineering, Physics, or a closely related technical discipline.

At least 9 years of direct, hands-on experience in crystal growth, crystal-growth process development, or high-temperature materials manufacturing.

Direct experience growing oxide and/or garnet materials, or demonstrably transferable experience with comparable high-temperature oxide crystal-growth systems.

Advanced working knowledge of crystal-growth process physics and parameter control, including the relationship of thermal profile, melt behavior, atmosphere, growth rate, and equipment configuration to crystal quality and yield.

Demonstrated familiarity with Czochralski, Bridgman-Stockbarger, Float Zone, and Skull Melting techniques; depth in the methods used at the site will be evaluated during selection.

Experience planning and interpreting experiments, analyzing process data, and applying statistical or structured problem-solving methods to improve capability and reduce variation.

Experience troubleshooting furnaces, controls, instrumentation, vacuum/inert-gas systems, and related growth equipment in a manufacturing or development environment.

Ability to write clear technical documentation and communicate effectively with operators, technicians, engineers, quality personnel, and leaders.

Proficiency with Microsoft Office and data-analysis tools used to document and evaluate process performance.

Ability to work onsite in Budd Lake, New Jersey. Position level, reporting relationship, travel expectations, work schedule, compensation range, and any export-control eligibility requirement are [TBD] pending business and HR confirmation.
