OptoMechanical Design engineer

To make electronics, you need chips, wafers, transistors, reticles, and... To make these, you must see, test and manufacture them at scale-faster and better than ever before. That's where KLA comes in. Whether you're early in your career or an experienced professional, you'll solve complex challenges, work alongside brilliant minds and help shape the future of technology. Group/DivisionThe KLA Services team consists of Service Sales, Marketing, Spares Supply Chain Management, Field Operations, Engineering, Product Training, Digital Solutions and Analytics, and Technical Product Support. Our services organization maximizes the value of our customers' KLA assets - with highly trained service and product support engineers providing installation services and 24/7 technical support and parts delivery through our extensive supply chain network. What You'll Do In this role, you will play a key part in advancing business priorities by delivering high-impact work across your area of expertise. KLA is seeking an Opto-Mechanical Design Engineer to develop precision optical and mechanical subsystems for advanced semiconductor inspection and metrology equipment. The successful candidate will work in a multidisciplinary environment to design, analyze, prototype, integrate, and validate high-performance opto-mechanical systems while collaborating closely with optical, electrical, systems, software, and manufacturing engineers. This role is ideal for candidates with a strong foundation in mechanical engineering, optics, and precision engineering who are passionate about developing innovative solutions for complex optical instrumentation. Successful candidates will possess strong mechanical and optical engineering fundamentals, experience with CAD and engineering analysis tools, and the ability to support the full development cycle from design through testing and integration. Expertise in geometric optics, optical alignment, precision engineering, FEA, and opto-mechanical design is highly valued, while experience with adhesive bonding, soldering, and cleanroom-compatible assemblies is considered a plus. Core 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, Computational Fluid Dynamics (CFD) and tolerance analyses to support design decisions. Support prototype fabrication, assembly, integration, testing, and troubleshooting, 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 to achieve system performance requirements. Develop optical mounting solutions that provide stability under thermal and mechanical loading conditions. Participate in design reviews and collaborate with cross-functional engineering teams. Support manufacturing, supplier interactions, and product release activities Preferred Technical Skills CAD & Mechanical Design Proficiency with Creo, SolidWorks, or equivalent 3D CAD software. Experience creating engineering drawings and applying GD&T principles. Understanding of tolerance stack-up analysis and precision assembly design. Optical Fundamentals Strong working knowledge of geometric optics, ray tracing principles, and optical alignment methodologies. Understanding of optical tolerancing and alignment sensitivity. Opto-Mechanical Engineering Experience designing optical mounts and precision opto-mechanical assemblies. Familiarity with optical and mechanical error sources and alignment stability considerations. Experience integrating lenses, mirrors, lasers, detectors, and imaging components. Analysis & Simulation Experience with FEA f
