The Principal Optical Design Engineer reports to the Director of Engineering, Laser and Optics.

You Will Make an Impact By:

• Leading the design and development of high-precision optics and optical systems, including complex multi-element assemblies, such as scan lenses and objectives
• Translating system-level requirements into optical architectures, designs, and specifications
• Performing optical modeling, tolerancing, sensitivity analysis, error budgeting, and trade studies to achieve demanding performance requirements
• Partnering with optical systems, mechanical, electrical, laser, manufacturing, and other engineering teams to integrate optical designs into complete systems
• Driving designs through fabrication, precision assembly, alignment, metrology, integration, and performance verification
• Working with suppliers and manufacturing teams to ensure designs are practical, manufacturable, and scalable
• Providing technical leadership through design reviews, feasibility studies, troubleshooting, and data-driven engineering decisions
• Mentoring engineers and serving as a technical authority in optical design and system development
