Senior Software Engineer; C#, .Net, C++

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.

KLA Instruments is our instrumentation division, which designs advanced metrology and inspection instruments used in both R&D and production across industries and academia. Our tools—ranging from optical profilers and nano-indenters to thin film and defect inspection systems—enable precise surface and material analysis. We partner closely with customers to enable R&D, improve yield, optimize processes, and reduce production costs through innovative hardware, software and application expertise.
