Job summary

Onto Innovation seeks an Optomechanical Systems Director to lead next-generation optical metrology systems for semiconductor manufacturing. You will drive innovation in optical architectures, ensuring nanometer-scale measurement capabilities for AI-driven process control and yield optimization.

Lead cross-disciplinary teams, oversee validation, and shape product capabilities across UV to IR, while traveling internationally about 20% of the time. A PhD/MS in Optical Engineering is preferred.

Qualifications

• 15+ years of experience in optical system design, preferably in semiconductor metrology or inspection.
• Proven leadership in managing technical teams and delivering complex projects.
• Experience with laser-based systems, spectroscopic techniques, and precision alignment.

Responsibilities

• Lead a team of optical engineers and Opto Mechanical Engineers in the design, simulation, and development of high-precision optical systems for metrology and inspection platforms.
• Architect optical subsystems for AOI products for semiconductor inspection systems, enabling smaller spot sizes, enhanced signal sensitivity, and advanced measurement precision.
• Collaborate with cross-functional teams to integrate optical designs into full system solutions.
• Drive the development of new technologies to cover UV to IR wavelength light sources, objectives, and imaging optics.
• Oversee design validation through lab testing, metrology, and performance metrics (e.g., MTF, SNR, wavefront error).
• Mentor junior engineers and establish best practices in optical design documentation, simulation, and prototyping.
• Interface with product management and customers to align optical capabilities with market needs and manufacturing constraints.
• Must be able to travel internationally to customer sites at least 20% of the time, with additional travel as business needs require.
