Mechanical Design Engineer – Process Media and Vacuum Systems; Pipe & Instrumentation Diagram

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.

In this role, you will play a key part in advancing business priorities by delivering high-impact work across your area of expertise. The Mechanical Design Engineer will own the system architecture for process media and vacuum systems in advanced semiconductor equipment, including gas, water, LN2, and vacuum distribution. This role is responsible for developing and maintaining key system documentation such as P&IDs, device lists, interface definitions, and related architecture documents, while working across mechanical, electrical, software, manufacturing, service, and reliability teams.

This engineer will also perform CAD work for the overall routing architecture, directly support detailed mechanical design, and guide contractors in routing piping/tubing and related hardware. Familiarity with MBSE is a plus.

• Own the architecture for gas, water, LN2, and vacuum distribution systems.
• Develop and maintain P&IDs, device lists, interface definitions, and requirements allocations.
• Perform fluid flow and thermal simulations.
• Create CAD models and layouts for overall routing architecture and hardware integration.
• Perform hands‑on mechanical design and guide support teams to perform CAD routing for cables, piping and associated hardware.
• Lead architecture tradeoffs and guide selection of major components such as valves, pumps, regulators, filters, gauges, manifolds, and sensors.
• Define system requirements and allocate them to impacted subsystems and technical owners across mechanical, electrical, software, manufacturing, service, reliability, and regulatory functions.
• Help define interfaces, interlocks, and sequencing concepts needed for safe and effective system operation (SEMI-S2, ASME, PED,…).
• Work across functions to support system integration, design reviews, troubleshooting, and productization including full documentation for high volume production.
• Support prototype build, system bring‑up, testing, and debugging of routing, distribution, and integration issues.
• Interface with vendors and internal stakeholders to communicate requirements clearly and help ensure technical solutions meet performance, quality, and documentation expectations.
• Prepare and support technical content required for requirements, concept, and detailed design reviews.

• Degree in Mechanical Engineering or related field.
• Strong experience with complex gas, water, cryogenic, and/or vacuum distribution…
