Sr. Mechanical Design Engineer - Wafer Positioning​/Motion Stages

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.

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.

KLA's Central Engineering organization is made up of nine Centers of Excellence (CoEs) spanning disciplines like automation, motion control, sensors, platform design, and packaging. Each CoE contributes not only technical deliverables but also deep expertise, best practices, and advanced tools that elevate both what we build—and how we build it.

In this role, you will play a key part in advancing business priorities by delivering high-impact work across your area of expertise.
We are looking for a Sr. Mechanical Design Engineer to join our Central Engineering team in Milpitas! As an engineer specializing in multi axis motion systems for wafer scanning with nanometers level vibration and accuracy, you will be at the forefront of creating fast, precise, reliable, and efficient electro-mechanical systems!
