Sr Mechanical 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 RAPID division leads the industry in reticle inspection solutions, helping ensure high lithography yields and cost-effective semiconductor manufacturing. Its systems support both mask shops and fabs by detecting defects early in the process, enabling faster, more reliable production.

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.

This mid-career mechanical design engineer will focus on sustaining programs for RAPID. Obsolescence is the key driver for the success of the RAPID legacy systems which are still in HVM. The candidate will play a pivotal supporting role for sustaining the design, fabrication and performance characterization of opto-mechanical modules, precision mechanical mechanisms, mechanical packaging, racks and chassis, and mechatronic systems. They will build technical relationships with vendors. They will have the opportunity to learn and eventually own the design process, including requirements specification, feasibility studies, analysis including FEA modeling, thermal, CFD, conceptual and detailed design, detail drawings, design review presentations, procurement of prototype parts, support prototype testing and system integration, and handoff to manufacturing! They will also own the process of taking projects from design concept through manufacturing build and will detail and address all issues thru the product phases!

• Create innovative designs involving a combination of the following: precision mechanisms, Ultra High Vacuum systems, opto-mechanical design, vibration isolation, and electronic packaging

• Develop a deep understanding of tolerance analysis, GD&T, error budgeting, flow up and flow down of requirements.

• Develop skills in finite element analysis, creep and stress relaxation, modal analysis.

• Perform meaningful thermal analysis: heat transfer, temperature gradients, thermal transients, thermo-elastic analysis

• Build vendor relationships: component fabrication, manufacturing process transfer, qualification.

• Select materials and resolving fabrication methods.

• Excellent interpersonal skills to be able to work with engineering, manufacturing and new product introduction team members in a concurrent environment.

• Demonstrate good understanding of physics and mechanics.

• Mechanical design, testing and troubleshooting.

• Excellent communication and team working skills are required.

• Familiarity with mechanical manufacturing processes including machining, sheet metal fabrication, welding, etc.

• Must be proficient in 3D solid modeling CAD. ProE/Creo preferred

Minimum Qualifications

Doctorate (Academic) Degree and 0 years related work experience; Master's Level Degree and related work experience of 3 years; Bachelor's Level Degree and related work experience of 5 years
