Senior Mechanical Design Engineer, Precision Motion Stages

About the role

KLA, a semiconductor inspection and metrology company, is looking for a Senior Mechanical Engineer to design a next-generation stage for high-vacuum platforms used in eBeam inspection. The work covers nanometer-level accuracy, stability and noise control, from concept through validation and sustaining, in close collaboration with controls, systems and manufacturing teams.

Key responsibilities

• Design, develop and maintain the mechanical architecture of multi-DOF ultra-precision motion stages for high vacuum, including structures, flexures, precision motion mechanisms and bearing, guide and actuation selection.
• Specify vacuum- and UHV-compatible materials and hardware with low outgassing and contamination control, and thermal management and drift compensation.
• Integrate metrology and feedback such as laser interferometers and high-resolution encoders, and handle structural dynamics, damping and vibration/noise isolation.
• Design parts and assemblies in Creo/SolidWorks with GD&T, run structural, thermal and vibration/modal FEA and tolerance stack-up analysis, and build, test and troubleshoot prototypes.
• Work with controls, systems and manufacturing engineers to integrate the stage and improve performance, manufacturability, reliability and serviceability.
• Manage supplier technical engagement for precision parts and subassemblies, and embed safety-by-design while developing service and production tooling.

Required profile

• Degree in Mechanical Engineering or a related field with experience in motion systems, precision mechanics or mechatronics.
• Minimum of 3 years' experience with a doctorate, 6 years with a master's degree, or 8 years with a bachelor's degree.
• Nice to have: experience with feedback systems (laser interferometers, high-resolution encoders, linear motors, air bearings) and with dynamic X-Y sub-micron stages tested with accelerometers and impact hammers; semiconductor capital-equipment design experience.

Required skills

• Creo/SolidWorks or similar 3D CAD, with several years of experience.
• Structural, thermal and vibration/modal FEA.
• Design-for-manufacturing across machining, sheet metal and castings.
• Working knowledge of data-analysis tools such as Python or MATLAB.

What we offer

• Base pay range of $141,300 to $207,233 annually.
• Possible performance incentives, medical, dental, vision, life insurance, 401(k) with company match, ESPP, tuition reimbursement, EAP, paid time off and family care leave.
