Job Summary & ResponsibilitiesAt Onto Innovation, you will play a key role in developing next-generation optical metrology and inspection systems used in advanced semiconductor manufacturing. As a Staff Optical Engineer, you will lead the design and development of optical subsystems that enable precise measurement of nanometer-scale features in logic and memory devices.
You will contribute to innovations across the full optical stack-from source and illumination design to imaging and detection-supporting AI-driven process control and yield optimization in leading-edge fabs.
- Lead the design, analysis, and validation of advanced optical systems and modules for semiconductor metrology and inspection
- Develop optical architectures spanning UV to IR wavelengths, including sources, illumination, imaging optics, and detection strategies
- Perform optical modeling and simulation (e.g., Zemax, Code V), including tolerancing, stray light analysis, and performance optimization
- Define specifications and collaborate with external suppliers to develop and qualify optical components and assemblies
- Drive prototyping, integration, and experimental validation of optical subsystems
- Develop calibration methodologies and procedures to ensure measurement accuracy and system stability
- Create documentation, test instructions, and integration workflows to support manufacturing, service, and field applications
- Collaborate cross-functionally with mechanical, electrical, software, systems, and algorithm teams to deliver fully integrated solutions
- Provide technical leadership, mentor junior engineers, and contribute to optical technology
QualificationsRequired- MSc or PhD in Optical Engineering, Physics, or a related field
- 7+ years of experience in optical system design and development
- Proven experience with optical simulation tools such as Zemax or Code V
- Strong understanding of optical system performance drivers (e.g., aberrations, polarization, scattering, noise, tolerances)
- Hands-on experience with optical system prototyping, alignment, and testing
- Experience working in cross-disciplinary engineering teams
- Proficiency in data analysis and automation using Python or MATLAB
- Demonstrated ability to own projects, define milestones, and deliver results
Preferred- Experience in semiconductor metrology, inspection, or lithography systems
- Knowledge of advanced optical techniques (e.g., scatterometry, interferometry, ellipsometry, lithography, imaging systems)
- Experience working with suppliers and managing lens development
- Familiarity with high-precision calibration and metrology techniques
Compensation & Growth• Base Salary Range:
$115,200.00 - $172,800.00, offered in good faith and based on experience, location, and qualifications.
- Additional Rewards: Annual bonus opportunities and potential long-term incentives tied to both company and individual success.
