Senior Machinist

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 seeking a skilled and detail-oriented Senior Manual Machinist / Precision Assembly Technician to support the manufacture, assembly, testing, and improvement of high-precision air bearing spindle systems. This position combines traditional machining skills with precision mechanical assembly, measurement, testing, troubleshooting, and documentation. The successful candidate will machine, fit, assemble, inspect, and test precision mechanical components to tight tolerances. The role requires the ability to work independently from engineering drawings, process documentation, and assembly procedures while maintaining the highest standards of quality and workmanship.

• Operate manual machine tools including engine lathes, vertical and horizontal milling machines, surface grinders, drill presses, and honing, polishing, lapping, and finishing equipment.
• Perform fitting, alignment, assembly, and adjustment of high-precision air bearing spindle assemblies and related subassemblies.
• Measure and inspect components using precision metrology equipment including micrometers, calipers, dial indicators, bore gauges, height gauges, optical measuring equipment, and precision test instruments.
• Assemble components to micron-level tolerances while ensuring proper fit and functionality.
• Conduct testing, performance verification.
• Analyze measurement and test data and make necessary mechanical adjustments to achieve performance specifications.
• Maintain accurate production records, inspection data, and test documentation using computer-based systems.

• High school diploma or equivalent required.
• Technical school, apprenticeship, or equivalent machining experience preferred.
• Strong understanding of machining practices, tolerances, fits, and geometric relationships.
• Ability to read and interpret mechanical drawings, GD&T, assembly drawings, process documentation, and bills of materials.
• Experience with air bearing systems.
• Experience assembling spindles, motors, precision stages, or rotating equipment.
• Familiarity with semiconductor, aerospace, optics, medical device, or precision manufacturing industries.
• Knowledge of balancing, vibration testing, and performance…
