Opto-Mechanical Design Engineer

About the role

KLA is looking for an Opto-Mechanical Design Engineer to develop precision optical and mechanical subsystems for advanced semiconductor inspection and metrology equipment. The engineer works in a multidisciplinary environment, designing, analyzing, prototyping, integrating and validating high-performance opto-mechanical systems with optical, electrical, systems, software and manufacturing engineers. The role suits candidates with a strong foundation in mechanical engineering, optics and precision engineering.

Key responsibilities

• Design and develop precision opto-mechanical components, assemblies and subsystems.
• Create 3D CAD models, detailed drawings, BOMs and engineering documentation.
• Perform structural, thermal, vibration, CFD and tolerance analyses to support design decisions.
• Support prototype fabrication, assembly, integration, testing, troubleshooting and documentation release.
• Partner with optical engineers to align and integrate lenses, mirrors, lasers, detectors and other optical components.
• Maintain optical alignment and positioning tolerances at the micron level and develop stable optical mounting solutions.
• Participate in design reviews, support manufacturing, supplier interactions and product release.

Required profile

• Minimum of 5 years of related experience with a bachelor's degree, or 3 years with a master's degree, or equivalent experience.
• Preferred: PhD in Mechanical, Optical, Aerospace, Physics or a related field; or 0-3 years of industry, research or lab experience with a master's degree.
• Strong foundation in mechanical engineering and precision system design.
• Ability to work in a multidisciplinary engineering environment.

Required skills

• CAD: Creo, SolidWorks or equivalent, engineering drawings and GD&T.
• Geometric optics, ray tracing, optical tolerancing and alignment.
• FEA for structural and thermal analysis, vibration and modal analysis, basic CFD.
