KLA Sr Mechanical Design Engineer - Wafer Positioning Stages 

United States, California, Milpitas 

532634780

The Mechanical Design Engineer will perform mechanical design of parts, assemblies, and tooling using Creo and generate drawings with GD&T for high performance wafer positioning/motion stages and wafer chucks. They will conduct design reviews, procure prototypes, and work with vendors for various parts and assemblies. The engineer will drive prototype testing, system integration, and stage servo tuning. They will test and qualify stages to ensure they meet performance and reliability requirements. They will create documents and procedure formanufacturing/assemblyof various systems and assemblies to ensure successful transition to manufacturing.

The Mechanical Design Engineer will also perform analysis and simulations, such as structural, thermal, vibration/modal FEAs, motorcurrent/voltage/powercalculations, etc. This position also requires working with other engineering groups such as controls engineers, systems engineers and manufacturing engineers to ensure seamless integration and to optimize performance.
