Senior Mechanical Design Engineer

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.

The Film and Scatterometry Technology (FaST) division delivers industry-leading metrology solutions essential to advanced semiconductor manufacturing. Its portfolio includes systems for measuring film thickness, critical dimensions, composition, and resistivity—key to developing and scaling next-gen IC processes. FaST partners closely with customers from early R&D through high-volume production, ensuring performance and process alignment.

What You'll DoIn this role, you will play a key part in advancing business priorities by delivering high-impact work across your area of expertise.

The Sr. Mechanical Design Engineer is responsible for developing innovative mechanical design solutions that meet demanding performance, reliability, and manufacturability requirements. This role spans the full product lifecycle—from requirements definition and feasibility through prototype validation and manufacturing release—and involves close collaboration across engineering disciplines.

Responsibilities will include:

Driving requirement specification

Conduct feasibility studies

Conceptual and detailed design, detailed drawings, using 3D solid modeling (ProE/Creo)
Conducting various analysis, such as fluid, thermal, vibrational, and FEA modeling

Understanding of Geometric Tolerancing (GD&T)
Detailed tolerance stack-up analysis

Hold design reviews throughout design process

Procurement of prototype parts

Prototype assembly and testing

System integration and testing

Create assembly and test procedures

Documentation release and handoff to manufacturing.

These tasks will require working with other engineering groups such as Optics engineers, Systems engineers and Manufacturing + Service engineers to ensure flawless integration and test at the subsystem and system level.

Work closely with and manage suppliers to ensure all design requirements are specified and achieved.

Address and resolve product issues through the product phases.

Design challenges may also include:

Precision design with large tolerance stack-ups Ultra-high vacuum design

Qualifications Desired In-depth understanding of manufacturing processes such as machining, welding, sheet metal forming and 3D printing

Driving requirements specification

Solid knowledge of precision machine design

Basic knowledge of vacuum systems

Solid understanding of statics, mechanics of materials, fluid flow and heat transfer

Experience in 3D solid modeling (Creo or Solidworks preferred.)Familiar with manufacturing processes including machining, sheet metal fabrication, welding fabrication and castings.

Strong mechanical engineering fundamentals, including design principles, machine elements, materials, fabrication methods.

Experience/knowledge in several of these areas: opto-mechanical systems,…
