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 Do

In 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.

• 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, vacuum systems, design of inspection equipment or similar instruments, motion controls, electronics, tooling & test fixture design, supplier management, new product introduction, manufacturing support
• Strong written and verbal communications skills
• Desire to contribute to team efforts to accomplish overall objective.
• Strong organizational skills with ability to multi-task, detail oriented.
• Ability to adapt and persevere in the fast-paced semiconductor industry
