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

About RAPIDThe RAPID division is the leading provider of reticle inspection solutions for the semiconductor industry. We deliver advanced inspection systems to both mask shops and semiconductor fabs, ensuring consistently high lithography yields and enabling cost-effective manufacturing.

Role Overview We are seeking a highly motivated Senior Mechanical Engineer to join our RAPID engineering team, supporting the development of next-generation semiconductor capital equipment. This role requires a strong technical foundation combined with an ownership mindset—from concept through manufacturing handoff.

The ideal candidate thrives in ambiguous environments, brings clarity to requirements, and leads complex engineering efforts end-to-end.

As a Mechanical Design Engineer, you will develop sophisticated precision mechanical and opto-mechanical inspection systems. You will take full ownership of the design process—from requirements definition and feasibility studies through detailed design, prototyping, testing, and manufacturing release.

Key Responsibilities Lead end-to-end mechanical design and development, from requirements definition through manufacturing release

Translate ambiguous or high-level requirements into clear, actionable engineering specifications

Perform and guide detailed engineering analyses, including:

Structural analysis

Modal and vibration analysis

Thermal analysis

Fluid flow modeling

Design and optimize systems with a focus on vibration isolation and damping performance

Drive concept development, engineering studies, and design decisions, balancing performance, cost, and manufacturability

Own subsystem or product-level deliverables, ensuring technical quality, schedule adherence, and accountability

Collaborate cross-functionally with systems, manufacturing, suppliers, and service teams

Support design reviews (RDR, CDR, DDR), validation, and system integration

Lead manufacturing handoff, including documentation, vendor engagement, and issue resolution during builds

Preferred Qualifications Experience in semiconductor capital equipment or similar high-complexity hardware systems

Familiarity with:

Vibration damping and isolation techniquesGD&T, tolerance stack-up, and precision engineering

Manufacturing processes (machining, sheet metal, welding, etc.)Experience leading…
