Job description

Principal Crystal Growth Process Engineer

Attalon is a leading technology partner to the global aerospace and defense industry, specializing in the physics of light. With over 500 employees in the U.S., Attalon engineers critical optical, laser, and coating technologies that enable systems to see farther, target faster, and survive the harshest environments. From high-energy directed laser systems to satellite optics and hypersonic thermal protection, Attalon equips the warfighter with the advantage of precision.

As the Principal Crystal Growth Process Engineer, you will lead the operation and optimization of crystal growth equipment, including bulk‑growth from a melt and solution‑based crystal growth processes. You will support the design and improvement of production equipment and processes, lead equipment or process transfers, and drive initiatives focused on troubleshooting, cost reduction, cycle‑time improvement, process stability, and metrics tracking. In addition, you will create and maintain process documentation and play a key role in developing new processes and products that meet internal and external customer requirements.

Responsibilities

• Identifies and monitors critical crystal growth process parameters, addresses factors that impact process control, yield, and throughput.
• Creates/maintains crystal growth procedures, SPC charts and related paperwork.
• Investigates data to establish correlations & trends, improvements, and root cause failure analysis for existing processes.
• Utilizes fundamental understanding of materials science and crystal growth to develop new growth processes to meet internal and external customer requirements.
• Leads the implementation of processes/technology from R&D to manufacturing.
• Supports manufacturing operations in capacity expansion and supplier qualification while maintaining quality and meeting product specifications.
• Generates scientific and technical ideas, contributes to the Intellectual Property Portfolio of Attalon by writing disclosures and patents. Participates in scientific meetings
