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/Division The Semiconductor Products and Customers (Semi PC) business unit designs, builds and sells KLA's product portfolio to help chip manufacturers meet high-quality standards for technologies like AI, data centers, automotive and electronic devices. Our inspection, metrology, and analytics systems detect and monitor defects across logic and memory chips, specialty semiconductors, wafers, reticles, advanced packaging, process equipment and materials. We also develop technologies for specialty processes, IC substrates, and PCB manufacturing, including etch and deposition, component inspection, and imaging and analytics. The RAPID division leads the industry in reticle inspection solutions, helping ensure high lithography yields and cost-effective semiconductor manufacturing. Its systems support both mask shops and fabs by detecting defects early in the process, enabling faster, more reliable production. 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. The Mechanical Design Engineer will support a major redesign of an existing semiconductor inspection module involving Ultra-High Vacuum (UHV), High Voltage (HV), precision mechanical assemblies, and complex electro-mechanical interfaces. The engineer will be responsible for mechanical design, analysis, documentation, prototype development, assembly support, supplier engagement, and product lifecycle support. The candidate will work closely with systems, electron optics, electrical, manufacturing, process, and supplier teams to deliver robust and manufacturable designs while maintaining system performance, reliability, serviceability, and cost objectives. Responsibilities Develop mechanical designs for UHV and HV subsystems, assemblies, and supporting hardware. Create detailed 3D CAD models, assemblies, engineering drawings, and BOMs. Apply GD&T principles, tolerance stack-up analysis, and error budgeting methodologies. Support redesign efforts for existing products with emphasis on reliability, manufacturability, and serviceability improvements. Conduct engineering analyses including structural, thermal, vibration, and finite element analysis (FEA). Participate in design reviews and support release of production documentation. Work with suppliers to develop fabrication methods, resolve manufacturability issues, and improve component quality. Support assembly, integration, qualification, and troubleshooting activities. Investigate failures and drive root-cause corrective actions. Collaborate across Mechanical, Electrical, Systems, Electron Optics, Manufacturing, Supply Chain, and Service organizations. Support prototype builds and product introduction into manufacturing. Desired Skills and Experience Good understanding of mechanical engineering fundamentals, physics, and precision engineering. Experience designing assemblies operating in vacuum, UHV, or cleanroom environments. Knowledge of high-voltage system considerations including insulation, creepage, clearance, and electrical interfaces. Experience with GD&T, tolerance analysis, and precision mechanical design. Familiarity with vacuum-compatible materials, cleaning requirements, and contamination control practices. Working knowledge of machining, sheet metal fabrication, welding, brazing, and precision manufacturing processes. Experience supporting prototype builds, troubleshooting, and qualification testing. Strong communication and teamwork skills. Proficiency with Creo/ProE or similar 3D CAD platforms. Experience with FEA and engineering simulation tools. Minimum Qualifications Doctorate (Academic) Degree and 0 years related work experience; Master's Level Degree and related work experience of 3 years; Bachelor's Level Degree and related work experience of 5 years About KLA We provide advanced inspection tools, metrology systems, process solutions, and computational analytics that make electronics possible, tackling complex challenges. From electron and photon optics to machine learning and data analytics, we seek perfection at the most fundamental level of matter in the universe. If you want to make electronics that push industries forward and make the world a better place, join us.
